Why Lightweight Aero Bikes Are The Future | GCN Tech Show Ep. 79

Why Lightweight Aero Bikes Are The Future | GCN Tech Show Ep. 79

– Welcome to the GCN Tech
show, this week we’ve got confirmation of a new bike,
a super light seatpost, a Greg LeMond tribute act, or kind of. – And our weekly talking point which is, why light-weight
aero bikes are the future. – Are they? The future is light-weight. And aero. Oh. (upbeat electronic music) – Why light-weight aero, or is it, aero climbing bikes are the future? – Yeah, 2019 is already the year of the light-weight aero
bike, but why are we seeing so many light-weight aero race machines? For the last few years the
focus has all been about the aerodynamic road race machine, that’s all well and good, but
there’s no denying about it, they weigh more than the climbing
bikes that we tend to see out there. But why now are we starting to see the light-weight aero bikes, Oli? – Well, I think if you speak
to any aerodynamics expert worth their salt, that saying
comes from Roman soldiers being paid in salt, fact,
then they will always say that a heavier aero bike is
faster than a light-weight non-aero bike over any terrain. Even over mountainous or hilly courses. – [Jon] Aero trumps weight. – Generally speaking most aero
bikes are around a kilogram heavier than their non-aero
climbing equivalent. And they typically save
around 20 watts of aero drag at 45 kilometers an hour. Although, this aero drag
saving can be more or less depending on the model, but
20’s a pretty consistent number. And this means that even on
a course with the profile of a queen stage in a grand
tour, aero trumps weight. You will go faster on
paper on the aero bike than the light-weight bike. – Yeah, the only situation, really, where a light-weight
bike has that advantage has to be on a summit
finish or a hill climb, something like that. Because, lets face it,
there is a caveat that if the climb is, say, five
percent gradient or less, then the aero bike, on paper,
will be faster, won’t it? – Even when climbing
aero bikes can be faster on shallow gradients. Drag is proportional to square of speed. Which means that the power
required to overcome that drag is proportional to the cube of that speed. Which means the faster you
go, the amount of power you need to produce becomes
exponentially higher. And so, at the speeds
that competitive amateurs, good club riders, and
professionals ride at, aerodynamics, it’s hugely important. – Yeah, that’s all well and good, Oli, but pro riders and team
leaders specifically, have consistently shunned the aero bike in favor of a light-weigh
bike, haven’t they? You can’t deny that. Think Movistar, you
get guys like Quintana, always riding the ultimate not the aero’d. And then Trek-Segafredo,
team leaders there like Bauke Mollema, pretty
often rides the Émonda instead of the Madone. – Yeah. – Just a couple of examples. – Yeah, I mean there’s loads,
but the heavier aero bike has definitely been a
tough sell to team leaders and a lot of pro riders. So having spoken to pro
mechanics, pro riders, and bike designers about this very thing, I think there are some reason for it. – Yeah, first up, a kilo of
weight is a lot more tangible than 20 watts of aero drag, because you can instantly
feel that, can’t you? What’s the first thing you
do when you get a new bike? – Pick it up, feel how heavy it is. – Yeah, that’s what
everybody out there does. Beginning of the season
you see every pro rider, they’re just picking it
up, and they always ask us, actually, at races, how
much does their bike weight if we gone and weighed it? It makes a massive
difference to them mentally. – Second is tradition. Us cyclists are a
traditional bunch, right? And it often takes us a
while to adopt new tech, even if there is a
measurable benefit to it. Now, a good example would
be everyone laughing at riders wearing skin suits
in road races a few years ago. But they soon quickly
stopped laughing when Johan Vansummeren won
Paris-Roubaix wearing a skin suit in a road race, rather than a time trial. And then Cav won the world championships also wearing a skin suit. The next week, well, everyone
was wearing skin suits. – Yeah. You went down the shops wearing
one as well, didn’t you? – Gainsburys. – Oh, cheesy. (laughter) What about then, the
demands of road racing? I mean, I think that plays a
big part in this, doesn’t it? Because, lets face it, the
team leaders, the winners, generally are drafting for a
great of the race, aren’t they? You know, they’re riding
in the middle of the packs, so those aerodynamic gains don’t
really effect them as much. – Well, interestingly though,
there have been studies on this, they do, so there is
still an aerodynamic benefit to riding an aero bike behind teammates. And in the bunch. But it is less. – Yeah, and I guess really,
quite often, a race is won on a climb, something like
that, or following an attack, so a lighter bike has that
instant advantage, doesn’t it? Because you see those
attacks go on a steep part of a climb or, I don’t know,
somewhere out of a corner, something like that. And having that lighter bike
it’s going to be quicker to accelerate, isn’t it? – Yeah, lower inertia of a lighter bike, and I think it’s at those
decisive moments in the race, they feel that the lighter
bike gives them an advantage. – Yeah. – So, on the one hand, there’s
an undisputed advantage to riding an aerodynamic bike. But, people psychologically
seem to feel that they’re just a little bit too heavy, so. – Enter the light-weight aero bike, or the aero climbing
bike, for a better word? I don’t know. Either way, both
professionals and consumers have obviously been demanding this, to have an aerodynamic
bike that’s also light too. Bike brands this year have
been all releasing them, haven’t they? – Everyone’s making one. – Who’ve we had so far this year? In fact, it started last year. – It was a couple of years
ago, it started first, really, I think, with the BMC Teammachine. Then we had the S-Works Tarmac, and the Focus Izalco Max,
that came out at the end of last year. – Pinarello F12. That at first, we didn’t
really think it was an aero climbing bike,
but at looking at it– – [Oliver] Oh, yeah, it’s definitely a– – [Jon] Yeah (laughs). Wilier Zero SR. – Yeah, Wilier Zero. We’ve had the Cannondale,
new SuperSix EVO. And the new SCOTT Addict come out. – Well, what do they all look like, Oli? – They all look the same (laughs). – Integrated cockpit, check. – Slightly downward top
tubes, often as well, check. – Aero tube shapes.
– Aero tube shapes throughout, and dropped seat stays. They all have dropped seat stays. – [Jon] And an aerodynamic
seatpost as well. Or slightly–
– De-shaped seatpost, tick. – [Jon] Tick, yeah. – The generally consensus
is that these new bikes are as light, in some
cases slightly lighter, than the previous generation
of pure climbing bikes. But also significantly more aerodynamic. But not quite as aerodynamic
as a full on aero bike like the Trek Madone. Now, I did some testing
a couple of years ago and we actually found that
the new specialized Tarmac was around 15 watts
faster than the previous non-aero Cannondale SuperSix
EVO at 45 kilometers an hour. Which is a significant saving. But, not quite as fast as
the full on super aero bikes like the Madone, or
the Venge, for example, which were around 20 to 25 watts faster at 45 kilometers an hour. So, it’s kind of interesting
to see that we’ve got that balance being struck. – Yeah, could we have reached
then peak carbon bike? Is this the optimum blend
of light-weight and aero? I mean, you love both, I’m not
that fussed about aero bikes. I like to have a really
nice light-weight bike. – I love an aero, I love aero bikes. – You obsess over it. But also over weight. Anyone who’s watched your
climbing videos will know that. – No, I think I’m really cool. But let us know what you
think in the comments. Which would you prefer? Full on light-weight, full on climbing? Or a full on aero or this half way house? This blend of both. Let us know, and let us
know which one you think looks the best as well
out of the new bikes that all look the same. – Yeah, also, by the time
this video has gone out there’s probably a new one
already been released, so. – There probably is (laughs). – Let us know what you
think about that one too. Now, after all that
light-weight chat, Oli, I’ve been scouring around on
the internet trying to find some light-weight components
for us to perv over, if you like. And a company I’ve found out
there is a Spanish company called Darimo, and they’ve
got something called the T1 Loop seatpost, just check that out. – I know, oof, look at
that, it’s 90 grams. 90 grams, right? 31.6 diameter. Handy. And it’s 400 millimeters long. – You’re not going to get a
much bigger seatpost than that, either, are you? – I just can’t fathom how
they’ve made it that light. But it’s got a really
light-weight carbon shaft, and then the way that the
clamping mechanism works at the top for your saddle,
is a bit unconventional. So they actually use Dyneema
cord to keep the weight down, which is the same material
as you may have seen on burred spokes as well. – I think they use that in
sailing as well, don’t they? Quite a bit, that sort of thing. So, yeah, it just wraps
around and then when you tighten up those bolts it does it’s magic. I love things like that,
I want to check one out. Right, moving on now to a
completely different area. With the Tour De France just days away, Mavic have launched a special
Greg LeMond tribute range of clothing. Now, Greg LeMond himself, he
famously used Mavic wheels and components in that 1989 Tour De France that he won by the slimmest margin ever. Just eight seconds. With a subtle nod to that victory margin, they’ve got a jersey,
a cap, and some socks, with some pretty discreet
eight logos on there. Just a nice little touch I think. Big fan of that. – In other news, the SCOTT that we spotted at the (mumbles) has been
confirmed, and we mentioned it in our main talking point as well. It’s the new SCOTT Addict
RC, and it’s been officially launched ahead of the Tour. So you can expect to see
the Mitchelton-SCOTT riders aboard this. The bike looks kind of
like a skinnier version of the SCOTT Foil. And a big feature of it
all the heavy integration. Particularly around the cockpit. There was loads of information in this on the press information that we saw. And interestingly, they’ve
gone with a one and a half inch steerer, which the SCOTT Foil also had. This is a slightly wider
diameter steerer tube, it’s also found on Giant’s and Canyon’s. A lot of bike brands still
use a one and a quarter inch steerer, but, yeah,
interesting it’s got that. – Yeah, it’s going to be nice
and stiff at the front end, isn’t it? And I think it looks really clean, now. Total and utter integration. Like you say, in the press
pack it was absolutely full of information on it. But one of the interesting things as well is that they’ve done away
with all of the stem bolts that you can visibly see. I nearly said physically,
well, it is physically as well I suppose. So they’ve got a magnetic
cap which goes over the top just to really clean that up. And of course, it’s stiffer as well, apparently 15 percent stiffer around the bottom bracket area
than it’s predecessor. – There you go.
– Yeah. Hopefully you’re going to check
that out at the Tour De France. You’re going there soon, aren’t you? – Can see one, yeah. – Yeah. (drilling)
(bell dinging) – It’s now time for screw
riding upgrades, buy upgrades. Where you submit evidence of
the upgrades that you’ve made to your equipment or
bikes, for a chance to win the ultimate prize, the
GCN eddy water bottle. – One that I’ve not had my lips around. – Well, you can have that one if you want. – That’s a bit weird. That’s a little bit weird. – Some of ’em are. – Fair enough. Right then, last week, I need to announce the winner actually,
don’t we, of last week? You’ve really thrown my
train of thought off. Either way, it was Joao, and
it was his wife’s fantastic Colnago build, that one
was an absolute stunner. And, in fact, Joao, then sent me email detailing more and more
stuff about that bike, it was great, including pictures of it when they actually bought it
rather than the finished item. Either way, get in touch
with us on Facebook to arrange delivery of the GCN
camel back eddy water bottle. Congratulations.
– Well done. – Right then, the first
contender this week is, Theo, from Cape Town in South Africa. – Right. – Theo, bought a 2011 Giant
TCR road bike second hand a few years ago on Gumtree,
and never began to imagine how well it would treat him. Theo, did many races with
the bike and couldn’t seem to justify after so many great
rides, why he should trade it in for a newer model. The only problem Theo had,
was that it started to show it’s age with a few scratches
and bits of wear and tear. Time was running out. Now was the time to give
the bike a full makeover and a bit of surgery. Custom paint, internal routing,
polish out all the scratches on cranks and rear derailleur,
and a new gold chain was agreed on.
– Yes, gold chain. – After surgery, it
definitely felt younger, and now has a few more years ahead. Theo, can’t wait to start
training with his new machine. – Right, let’s see it then. – Right, here’s the old TCR, advanced SL. They were lovely bikes, weren’t they? – Yeah, nice bikes.
– Absolutely lovely. Look at that paint job (gasps). Theo, very naughty.
– That is very nice. – Yeah, that is, isn’t it?
– Nice. Great job. – That is fantastic looking bike. What’s that bar tape? Has he got some fancy
pearlescent mirrored bar tape? – Strange bar tape going on there. – Strange, but, I’m strangely attracted to it. – That paint job’s brilliant. I love it, that’s great. – Side on, that looks just
like a blue bike, doesn’t it? Metallic blue.
– Looks like he’s polished his cranks and stuff as well. – Yeah, cheeky.
– Given it a polish. – Right (laughs), go on then. Who’s Theo up against this week? – Theo is up against, John,
from Sheffield, in UK. – That’s just down the road from where you’re originally from, isn’t it? – It is, yeah. – Maybe you know him. I feel
sorry for you, John, if you do. – I bet John looks good
on the dance floor. Anyway, every year while
helping his dad tidy his garage, John, got the usual
discussion about his dad’s old 1990s British Eagle
touring bike, at the back, covered in dust, unloved,
unridden for over 15 years. And, well, he’d ask his dad,
can I have it and restore it? And the answer was firmlier no. – Go away. Something like that imagine. – But, just before Christmas this year, apparently, no, he was like, yeah, go on, you can restore it. Christmas miracles do happen. – Father Christmas. – And so, half a year
later, after he’s been restoring this bike,
trawling the internet for bargain parts and tinkering in his garage, and modernizing it, and turning
it into a racier looking machine. This is the result. Look at that.
– Oh, my. – Look at that frame.
– Yeah. Good work with the decals. Decals, stickers. – [Oliver] Look at that blue. – [Jon] Nice to find some of those, bet you found them on eBay. – [Oliver] Look at that. – [Jon] That looks good now, doesn’t it? – [Oliver] I like the orange and the blue with the Dedacciai Bar Tape,
that’s nice, isn’t it, that? – [Jon] Look he’s got orange skewers, orange bolts in the pannier rack. – [Oliver] Those prime wheels. They’re a good value set
of wheels, they look smart, don’t they? You know, don’t break the bank,
looks smart on that build. – [Jon] Yeah, he’s got
an orange Garmin mount, or Wahoo mount, whatever
it is on the bars. – [Oliver] GP4000’s as well. – [Jon] Yeah, look at
the saddle, that’s blue, a little orange stripe through the middle. I tell you what. – [Oliver] The color coordination
is through the roof there. – Blue and orange always looks good. Cantilever brakes. – Well, make sure you lock that
up if you go down eccy road. Anyway, Theo or John?
– Yeah, who’s it going to be? Vote up there, top right hand corner. And remember to submit your bikes into the screw riding upgrades, buy upgrades, by using the uploader tool
down there in the description. Bike of the week time now,
and you will remember that last week there was a
very special head to head, it was the Lotus 110 super bike, up against the Wilier Zero
SLR, new bike that came out. And unsurprisingly, or
surprisingly, actually, for me, was the Wilier, yeah. That won. – [Oliver] Yeah, I’m a
bit surprised by that. – I mean, we will have these head to heads every now and then when
we deem it necessary, because we’re the enforcers
of this, aren’t we? – Speaking of which,
Jon, I deem it necessary. – Oh, right, okay. – We should have a foursome. – Right? Go on, I’m intrigued. – So, all the new aero light-weight bikes. The Pinarello F12, right,
versus the new SCOTT Addict RC, Cannondale SuperSix EVO,
and the Wilier Zero SLR. Chuck ’em all in, all four. – Yeah, you decide, up there, vote away. – Which looks the best? – I think that’s the first
time we’ve done a four thingy up there, init? Bike vault time now, and
I hope you know the drill. But if not, a quick reminder,
if you want to submit pictures of your bike to hopefully
go into that bike vault and get rated either nice or super nice, make sure you use the
uploader tool found there in the description below. And, Oli, what happens, mate,
if they get rated super nice? – If they’re super nice then, Jon, will ring the bell. – Correct. I guess I’m ringing the
bell again this week. – Yes, yes you are. – Good to have you back, mate. Right, okay (laughs), the
first one in this week, it comes in from, Isidore. They’re from the third rock from the Sun. What that means? It’s a television
program, it’s a C4 Joker. Ever seen one of those before? – [Oliver] Yeah. Once. Bizarre looking piece of
cycling history, isn’t it, that? – [Jon] They were all the
rage for about two weeks in about 1994. – [Oliver] Well, it is
very Saturday morning TV paint scheme on it, isn’t it? It’s very Live And Kicking. – [Jon] This is what we
said earlier on about the carbon, you know how all
bikes used to look the same? And then when carbon came
along we got funky shapes. This is funky. – Yeah. But what on Earth is that
foam thing hanging from the top tube with like Velcro? – I don’t know. – What’s that about? Isidore, let us know what that is. This has potential, doesn’t it? – It does, yeah.
– It has massive, massive potential. But I’d love to give it a super nice, but it’s just– – [Oliver] Just that foam,
the Velcro thing going on. What is that? That’s unforgivable. We can’t just let that go. – You can’t!
– We can’t let that go. That sets a dangerous
precedent if we let that in, because of that. It’s nice. – Yeah, surely you go
pockets on your jersey. Right, who’s next? – Right, we’ve got Eric from Boston. In the US of A. – Oh.
– Oh, look at that. – [Jon] That’s nice,
Colnago Master, isn’t it? – [Oliver] And again. Orange and blue. Like a bit of orange and blue. – [Jon] Yeah, it looks good, always. – [Oliver] Very nice. – [Jon] Straight away we can
see, valves not lined up. Not the best angle to take it at. – [Oliver] Little big chain ring combo. Not got it in the Biggie Smalls. – The biggie? Don’t ever say that again. Don’t ever bring Biggie into the tech set, well, you can actually, I quite
like that, it was well done. – Biggie Smalls is what we want. – [Jon] Bit of a scratched up seatpost. Isn’t it Controltech seatposts? – [Oliver] There is potential there. – [Jon] Again, potential, bottle
cage only on the seat tube, not on the down tube. There’s a few things here going on. That I’m just not happy with. – [Oliver] It’s a very nice
bike, but, there’s just… – It’s a nice bike. It is a nice bike. Right, next up is, Sam,
on the shoreline trail in Mountain View, California. Apparently, Sam, took the long way home. Whenever I hear that, long way home, I always think of, is it Supertramp? – [Oliver] It is, yeah. – [Jon] They play that, don’t they, at the end of cricket innings? Or batsman’s innings. Yeah, Supertramp. Either way, it’s a specialized. Big stem. Reflective bar tape? – Well, he’s used a flash, hasn’t he? And then that’s brought
out the reflective element on the bar tape, but it also
emphasizes the gold chain. – It does. We always have a winner, don’t we? Every week. – I like that.
– Yeah, Envy wheels. Do you know what? That actually reminds me,
when I lived in Antwerp, believe it or not, they used
to have sunsets like that in Belgium. Yeah, on the river there, on the skelder. Yeah, that is really nice. Yeah, yeah, super nice, right. (bell ringing) Okay. – Next up we have got, Chuckie, in Hong Kong. I do hope this is not, Chuckie, as in child’s play Chuckie. But, Chuckie, has
(laughs) sent us a video. This is GCN Tech show
first, a video submission to the bike vault. – [Jon] Let’s have a look– – What a good shot.
– The camera work. Look at this, this is
well edited, isn’t it? – [Oliver] Do you think he wants a job? – [Jon] Oh, Chuckie. (laughter) The Chuckmeister. – [Oliver] Yeah, oh, look at that. – [Jon] Look at that. This is brand new, this is like an advert for the bike, isn’t it? – [Oliver] Yeah. (gasps) GP fat tubeless. Tubeless 5000’s, look at that, oh, come on. – Look at that. That’s beautiful, init? – Super nice.
– Chuckie. – Super nice.
– Yeah, super nice, just for the fact it’s in a video. – GCN Tech show first. Brilliant.
– Saw it here first. (bell ringing) – And finally, it is
Paul from RAF Cosford, or rather, just outside of RAF
Cosford, with his Dolan bike. It’s a lovely looking bike. – [Oliver] Is that in the Black Country? Is it in the Black Country? – [Jon] Yeah, yeah, it’s just
near Wolverhampton, yeah. – [Oliver] Paul from near Wolverhampton. RAF Cosford. – [Jon] Yeah, lovely looking
bike that, init, though? Again, orange and blue. – [Oliver] Yeah, oh, look at
that Hawker Siddeley Hunter in the background, though. – Oh, you know your aircraft. Now, incidentally, there
was just 415 of those Mark 6 Hunters produced. And 380 of them went to the RAF. The greatest number of any Hunter variant. – Well, that’s completely
correct that, Jon, but this variant actually
had improved flying controls over previous versions
of the Siddeley Hunter, making an ideal acrobatic aircraft, serving with various
display teams including the Black Arrows and Blue Diamonds. It also had the Rolls-Royce Avon engine with it’s 10,150 pounds per square ton output, and dogtooth wing leading edges. It was armed with 30mm ADEN cannons, and bombs or rockets which were
mounted on underwing pylons. And the RAF Hunter F
Mark 6S entered service in October, 1956. – [Jon] Blimey, you
really do know your stuff. Weren’t some of the later ones, as well, the wings were actually modified slightly to be able to carry heavier loads as well? – [Oliver] Yeah, that’s
correct, they were. And they actually saw
service right up until 1963, and still in 1980s as a
training role as well. – [Jon] Well there we are. A
little bit of history there. Beautiful looking airplane. – [Oliver] Siddeley Hunter a super nice? – [Jon] Yeah, definitely,
and as for that Dolan, I like that as well, it’s
nice and clean, isn’t it? Bowls lined up vertical, big chain ring. You know, middle of cassette– – [Oliver] Something I’ve not seen before. – Go on.
– Color coordinated saddle bag. – [Jon] Oh, yeah, and also bottle cages. One orange, one blue. It kind of does the job, doesn’t it, that? – [Oliver] I mean, mismatched bottles, shall we let that slide? – [Jon] I can let that slide because of the beautiful backdrop. And also it’s just a clean
looking bike, isn’t it? – [Oliver] That is, yeah, nice. – [Jon] Yeah? Super nice. (bell ringing) I’ve enjoyed that finishing bike, yeah. Get involved, submit your
bikes to the bike vault, use that uploader tool. – Or airplanes. We like them too. – Airplane vault. (laughter) Nearly time for the end of the show now, but we just thought we’d go
through a few of our favorite comments underneath the
videos of last week. First up, one aimed at me where I turn that fixed wheel bike, you
know, the conversion one, you know what I’m talking about. Elliot Flowers said, referring to me, I’ve seen this guy in a video
painting sash window frames. That’s just weird. Unless you’ve been filming
me, or someone else has. – Send us a link to this video. – I want to see it, what’s he look like? – Yeah, and on a video of Hank riding in the rain. – [Jon] No, he’s presenting in the rain, he was presenting the Pro Bike, wasn’t he? – [Oliver] Yeah, and it says, poor James, suffering in the rain, some
one get this man an umbrella. – [Jon] No, he loves it, doesn’t he? – No, he doesn’t really mind the rain. – Yeah, he doesn’t mind,
yeah, doesn’t care one bit. And underneath last weeks
show, Callum Gill, said, the ultimate car for a
cyclist or mountain biker is a 90s or 00s Subaru
Outback or Forester. Oh, I dunno. Actually, yeah, my mate
had an Impreza Estate, that was terrible for bikes. But yeah, Forester, I think
Ed Clancy had one of those. Twin turbo.
– Did he? – Yeah. What would be your ideal car? – Well, this is purely speculative, and the manufacturer in question
will have to send me one so that I can confirm
this, but I would speculate that the best car would be a McLaren 570S as used by Bahrain Merida. – Yeah, good point. Or it could well be the
Jaguar that Team Sky used a couple of years ago, that
was highly practical as well, wasn’t it? – F-TYPE R with the V8. – Yeah, specially scooped
out boot, wasn’t it? So a wheel could get in there. Something like that.
– Yeah. You can put a C sucker
on the back can’t you? – You’re right, yeah, you could. Right, anyway, do stay
tuned to the channel ’cause we’ve got loads of great content coming up, haven’t we? Because you’re off to the Tour De France. – I am, I’m going now, actually. – Are you? Okay, all right, mate,

100 comments on “Why Lightweight Aero Bikes Are The Future | GCN Tech Show Ep. 79

  1. The aero fad is great, it means the market is flooded with lightweight superbikes going for cheap, send em my way! For anyone who sees through the spin, your body is the biggest drag, get yourself smaller for free aero gain.

  2. The Specialized was a nice bike, but that goes against the precedent for high photo-quality, which ironically, precedent was a concern for the C4 because of some neoprene…some inconsistency there, boys…

  3. Please. Make a review about the new Trek Madone SLR 6 Disc Speed. You will find interesting. Greetings from Santiago de Chile.

  4. The way I see it, a lightweight aero bike is just the natural progression from having lightweight and aero bikes. Weight is obviously important, drag is also obviously important, and sacrificing either for the other means giving up speed—even if an aero bike is faster in 90% of situations, you're still going to have that summit finish up the Mortirolo where if you decided to ride the Propel instead of the TCR, you're going to get dropped by the guy on the Helium or the SuperSix. But if you've got one bike that is both lightweight and aero, then you don't have to give up anything.

  5. This is balogni everyone knows the future is Drum roll 🥁 the flintstones leg powered vehicles.

  6. Aero bikes or climbing bikes and any skin suits are pretty useless if the rider has a weak endurance and strength. Training is much more important.

  7. Olliepedia's knowledge on aircraft there…almost like you were reading it off a website 🤨🤔🤣

  8. Hi Jon & Ollie, great show – keep it up!! Would the Lapierre Xelius SL range be considered as a light aero bike?? Thanks

  9. : There are some interessting details at 13:56. Like he drilled holes in the frame to route the cables internally now(before they were external) and the way the brake cable for the rear break goes around the head tube.

  10. I'm quite heavy (although have lost 3kgs this year!- just about half a lightweight climbing bike)and have the aerodynamic profile of a massive potato. I want a straight forward bike- the new supersix evo might mean I can pick up the old model cheap- happy days!

  11. What's better if you are 2nd wheel? I suspect all those aero gains are neutralised if you're in a group whereas weight is not – so the best bike could be a light weight one with a rider who knows when to attack!

  12. Always these discussions ignore the simple reality of the unending variable of the rider. No matter how light or how aero, the physiology of the engine (the rider) will always determine the level of gain. So for all the tech assistance gained by high priced, ridiculously researched 21st century offerings, they are still only as useful as the capabilities of the rider. Marketed to the masses the truth is, nearly all these things benefit the very smallest percentage of riders. Spend $12000 on technology or 12000hrs on training? We all know the answer but if it ever caught on, the industry would go broke over night

  13. I just got a new carbon road bike, it is super light but as you said it is very similar to all the bikes you mentioned. It has an integrated cockpit and stem, slightly sloping top tube and it is aero. But I love it, it handles brilliantly and due to its super lightness, it can climb really well and descend even better so I think this new design found on the Pinarello Dogma F12 is brilliant because it is like an all-round road bike that is good at climbing and descending.

  14. One reason the team leaders will chose a climbers bike is the time they spend in the peloton out of the wind. It will deminish the benefits of aerodynamics.

  15. The third rock from the Sun is the 🌎 Earth. It’s not a TV reference but rather since she didn’t want to disclose her location.

  16. I prefer round tube titanium or steel bikes. I just like that classic look better. These new carbon bikes look like a major pain in the ass to take care of.

  17. Black country= Quarry Bank (bonk), Old Hill, Brierley Hill, not RAF Cosford!!. The Black Country made chains for ships like Titanic. Need a video on how to "aero" my Brompton!!. Keep em coming guys !!!

  18. Light & aero, I'm sold… sort of. However, if Trek comes out with the rumored threaded bb 2020 Emonda, I'll go for light weight.

  19. GCN should do a poll on what riders really look for when they go out (multiple choices allowed). Beautiful scenery? Challenging climbs? Strava segment hunting? Increased average speed? I would imagine the latter would actually be surprisingly low in many cyclists priorities.

    Also, if youre getting faster times on Strava segments without upgrading to newer, more aero equipment then isnt that the solid gold proof that youre improving as a rider…surely thats more satisfying than knowing its down to your new aero bits and bobs?

    Just dont get the aero thing for amateur cyclists….sorry

  20. Can't believe the Lotus bike lost out to the Willer. The Willier is just another bike that will be forgotten in a few years while the Lotus bike is a piece of history.

  21. My 2015 Giant Propel weights 6.9 kg, and that last 100g is all functional weight that makes the bike faster than the lighter option. And my saddle of choice only comes in 172g. I suppose I could sand off the paint.

  22. the bar tape at 14:00 is just reflective bar tape. it is this exact product:

    i use it, it has no grip, but undoubtedly is the most eye-catching. worth the money

  23. C’mon Ollie, obviously a McLaren Senna is the best for the job. That’s what they should send you.

  24. Uhm Pinarello made the F8 xlight lightweight aero bike for Froome in 2016. He won the TdF on it. GCN even featured it in a video.

  25. There are several good non aero frames out there. Most tour riders and a lot of amateurs use one with aero wheels and equipment in general. So how much does an aero frame help over a non aero frame with aero equipment? Key is “with aero equipment”. Ex. aero wheels, bars, rider with aero helmet, etc. on both frames. Big question because it is so common to use non aero frames with deep dish wheels etc.

  26. lightweight aero bike for most things but if I was doing something like the Fred whittion lightweight climbing bike

  27. Team leaders are supported by teams, most of their time is spent in the wheels. When they attack they need acceleration to drop their opponents.

  28. Why does this aero vs lightweight argument matter for anyone except for professional riders? 1 kg difference in weight is nothing compared to an 80 kg person, especially if that person is hauling stuff, and the aerodynamic profile of any bike is nothing compared to the person riding it, especially if that person has a jacket on or something. The differences in performance you will see between these two types of bikes should be negligible except in the most extreme cases.

  29. Let's discuss how to make the rider more aero. The bike is not the issue, the sail on the bike is the non-aero part that needs addressing.

  30. I’m a statistician. I would like to build or see a manufacturer test, measuring effects of normal slowing and acceleration on energy consumption with aero and lighter non-aero bikes. Not sure of results, but Strava data with watts might be enough to perform the test. Does numerous starts and stops of real road biking make the lighter bike the better option? 🤔🤷‍♂️

  31. A bike is not "20-25W faster at 45kph" I think the word is "efficient". That been said, yes, the future for security and desing limits will be aero and lightweight but the differences will be noticeable in the pro peloton, not in the average speed of a recreational cyclist.

  32. 2:17 – "The power required to overcome that drag is proportional to the cube of that speed… so the amount of power you need to produce becomes exponentially higher."

    No! Not exponential! You said it yourself – it's polynomial!

    (Studying math ruined everything.)

  33. Ive had a lightweight aero bike for 3 years its nothing really new. Tbh i just like the look and the handling but uts not faster once you whack on the lights and tool bags and bottles etc. The watrs are a few in the real world.

  34. Of course the answer is aero.

    All you 'traditionalists' who insist a bike should have round tubes and caliper brakes are holding the rest of us back.

  35. Light weight. Expecting my $5000 Aussie dollars will build me a sub 6kg bike. It would not buy a nice Aero bike.

  36. Ollie, if you were asked to repeat your Everesting attempt, would you use an aero lightweight bike (from any manufacturer) and try to break your previous record? 😁

  37. Yep, but those aero bikes available on the market gives only marginal gains, because of manufacturers must comply with UCI rules, so that is why we are working on true aerodynamic bikes with customized bike frames at 10x times cheaper price since no need for lightweight unless someone compete at top level 😉

  38. I find it ironic that the focus bike that was showcased in the video in the bike vault had trouble with camera focus at the end.

  39. i think if someone gave me a super bike, i wouldn't be fussed if it was aero, lightweight, or climbing …

  40. I'd personally go for something in between when it comes to the aero battle. A bit of aero and a bit of light climbing wieght… As for aero bikes, I do agree they look almost alike. But if I have to pick one, I'll go for the new 2019 Cervelo S5. Such a beautiful machine. I'm considering placing my life savings on one!

  41. #askgcntech I have a sportive coming up in 1 week time, should I change my soon to wear out tyre or not? The 90km sportive is mainly flat if it helps.

    My concerns are the feel of the new tires and if it needs a break in period

  42. A person makes up 80% of the drag experienced while cycling. 45 Kph is roughly equal to 465 Watts of power on the flat (80Kg Rider + Bike). Saving 20 Watts as quoted would give the same speed at 445 Watts (= 44.25 kph). So roughly the time saving at 45 kph for one hour on the flat with no drafting or wind assistance, is approx. 750m. Going with the rough calculation that the saving is approximately 9 Watts at 30kph (30 kph roughly 155 Watts on the flat) You could gain up to 0.5 Kph with on your Pinerallo F12. However losing 10Kg in body weight will save you approx. 5W on the flat alone in rolling resistance at 30 kph, much more due to gravity when ascending. How many cyclists can sustain 30Kph on regular rides? let alone 45kph for a full hour. Yes Aero trumps light weight but for mere mortals the differences are minimal. So if you have an aero bike great, if not don't worry about it and ride your bike. It's all marketing hype.

  43. Light aero is good. If I was so worried about light weight, I would not carry this fat pack in front of me wherever I go.

  44. I have a lightweight aero bike for sale. Cheap. It broke right in the middle. Just snapped in two.

  45. I just spent all weekend in some California mountains riding up 10% grades at 4-7 mph. Then, I'd recover by mostly coasting down the descents. My only competition is myself on the previous ride. Aero bikes can sometimes look cool, but the classic look of a light climbing bike almost always looks better to me. Never underestimate a cool looking bike as a motivation to ride. In addition, I like working on my own bikes, and all the cables going through the stem seems like a giant pain in the ass. So, if I want a precise-running, easily tweak-able, cool-looking bike for getting up my favorite roads, an endurance/climbing bike is the most fun for me.

  46. TechShow is becoming my favorite of the GCN offerings! Dare I say it may soon top the GCNShow! Well done lads!

  47. The Specialized Tarmac is a climbing bike with aero attributes and it has a near untouchable winning record. It won stage 3 today and had a great spring campaign too.

  48. #AskGCNTech
    Hi I'm currently riding on an old Battaglin Stealth frame (size 60cm). The bike is a DIY bulit with the Battaglin frame, a Thompson fork, 105 (5700) 2×10 groupset and Vision Team 30 wheels… overall a god and comfortably bike 🙂

    But the frame is a bit to large for me… I'm 184cm tall and a frame size 54cm ore 56cm should fit me better… This also meens that the reach is a bit to long… but I'v kind of sorted it with a 80mm stem and a short reach handelbar.

    I'm on the lookout for another bike BUT I'm NOT that interested in getting a complete bike… I love the built and therefore looking fore another frame… And here comes the question 😉

    What kind of frame would be worth looking for??? I'm from Denmark so it's mostly flat open landscape and I'm an average rider… Should I look for an aero or a more "normal" frame? Alloy or Carbon dosn't matter 🙂

    Best regard Jannik

  49. Couldn't marketing be a factor aswell? If the brand produces an aero bike and a climbing bike it would be ideal to have a top sprinter on the aero and GC rider on the climbing bike. Then they sell loads of both.

  50. If manufacturers are constantly making bikes that weigh below the UCI limits, why not make them aero to add a little more useful weight rather than just filling the bottom bracket with a slug?

  51. I think that Roman soldiers being paid in salt is arguable. They were also paid a 'stipendum'. It could be surmised that salt was a ration rather than wages.

  52. Too lazy to look this up, but isn't there a weight minimum for UCI legal and other cycling organizations? I ask because it seems like that makes the tradeoffs potential easy to make – you take the most aero bike with the ridability/usability that meets the minimum weight, and then wait for the next technology marvel to give you a bike that would otherwise be lighter, and instead sneak in more of the heavier aero features until it's back are barely over the minimum weight…. no?

  53. Saddle bags are out, not clean looking. You should be able to easily carry what you need in your jersey pocket for rides under 100km

  54. I have never ever been out performed in 30 years of competitive cycling because a rider was on a better or lighter or more aero bike. Skill and fitness wins the day.

  55. just got back on a bike after 40 years, recently purchased a Trek fx2 in blue, like the show and picked up a few tips

  56. I love this channel and am beginning to morph (in my late 50's) from one who always used bikes as transport into one who is beginning to cycle for sport/fitness. I have moved to Waterford in Ireland and live in the comeragh mountains and we have some cracking hills here (it will always bust me when I am coming home with 20kg of food shopping in my panniers (specialised 'Source' hybrid) to be passed on a hill by decent amateur cyclists with super lightweight bikes to the sound of 'get a move on granddad!!!)
    I am nowhere near appreciating the differences between pure aero V lightweight but at least I am beginning to consider getting a road bike. Baby steps! (also I do long distance walks…..Pacific crest Trail in 2021 and then Ireland to China the following year (on a touring bike)

  57. Hang on, don't all the pros try to get next to the UCI min weight limit anyway?  So with all the tech out there can't aero bikes and climbing bikes in the pro peloton be the same weight anyway?

  58. With that whole "aero" thing, at what speed does that aero frame actually start to make a "real" difference ?
    Keep up the great work, Guys !
