Is Being Aerodynamic Uphill Important? | Ask GCN Anything Cycling

(funky music) – We’re going to start this
week’s Ask GCN Anything with a couple of questions
that we asked you lot this time last week. Namely, define chipper and chopper. We had quite a few answers,
but we’re gonna go for one definition for each, and
let us know if you agree or disagree in the comment
section down below. First up, Gryffes defines chipper. It says, it refers to a race
where the standard is so low, the prize is a fish and chip dinner. Calling someone a chipper
implies that’s the level of rider that they are. And James Ashcroft defines chopper. He says in the youth category,
they define it as someone who can’t ride their bike
properly and who is liable to cause a crash. Very interesting indeed. Okay, onto the first question
that we are going to answer here today, from Nate Nelson. Are there any differences
between a male and a female bike, besides the colours? Well, yes there are other differences and it’s mainly down
to sizing and geometry. So, a few bike companies
have done some research and also looked into a database called The Global Body Dimension Database, which apparently shows that, in general, women have got a slightly
shorter torso and reach, in comparison to their
leg length, than men. And so a lot of women-specific
bikes have a shorter top tube and also a shorter
stem, to take that into account. However, as with everything
in life, not everybody is the same, so even if
you are a woman, you might not be best built for
a women-specific bike. So always try before you buy. And if you want a lot more detail on this, you should watch this next
video, in which Lucy Martin asks, do you need a women-specific bike? – So, back to the initial question. Do you really need a women-specific bike? Well, the honest answer
is, it actually depends. I raced almost every
season on a men’s bike, but I can see how some women would really benefit from
having a women’s specific bike. Let’s face it. Everybody’s different
shapes, different sizes, regardless of gender, so you need a bike that basically just fits. And that may be a women-specific bike. – Okay, next up is a question from Rajan Chitrao, apologies again for the pronunciation. What should I buy as my first bike? A road bike, a Cyclocross
bike, or a mountain bike? Well, that is a very
difficult question to answer without knowing exactly what type of riding you are hoping to be doing. And I’m guessing from the
fact that you haven’t written it down, you’d actually
know, yourself, exactly what you want to be doing. So I would suggest going
for that middle ground of the Cyclocross bike,
or indeed, a gravel bike, because they’re very versatile machines. They’re pretty fast on the
road, albeit not quite as fast as road bikes, but they’re
also more than capable of handling some off-road conditions. Maybe not the gnarliest
descents in the world, but certainly gravel, fire roads, and also some single track as well. And if you really start to get
the feeling that it’s slowing you down slightly on the
road, and you want some more performance, you can always
buy a second set of wheels, with some slick tyres, or
just purchase the slick tyres on their own and put them on
the bike when they’re needed. Now, we did a day’s filming
a couple of years ago in Wales, where we explored
the differences between a gravel bike and a road bike. It really was great fun
indeed and it’s coming up in this next video. – You can punch it in, Dan. – [Dan] Sod off. (mystical music) (rock music) (rock music)
(Matt, laughing) – We should start the quickfire
round off with a question from Andrew Lord, who says,
when using a maintenance stand on a carbon bike with a carbon
seatpost, where’s the best place to clamp it? Well that is a very good question, indeed. You should always avoid
clamping any of the tubes on a carbon frame set
because they’re not designed to withstand that force from
the side, only to be strong in the direction they need
to be when you’re riding. The seat post one is a
difficult one, though, because some people say it is designed to withstand that force. Because, after all, there’s
a seat collar and clamp to prevent it slipping down. Other people say that if it
is a very light-weight carbon, you do risk damaging it. So there are a couple of
solutions, the cheapest of which is to buy a very cheap
steel or alloy seat post, which you simply put in when
you want to put your bike on the maintenance stand, or
the slightly more expensive option is to get one of those
stands that the pro mechanics use, where the fork dropouts
are secured at front and the rest of the
bike’s weight is propped up at the bottom bracket
and you can spin it round. So I recommend one of those
if you have the money. Next up, Gingercoastie says why are tubs faster than clinchers? Tubs being tubular tyres,
of course, that are stuck onto the rim as opposed to
clinchers, which you mount on and have a separate inner tube. I’m not exactly sure, Ginger, that they are necessarily faster. They might be in some cases,
but during my time as a pro I did a lot of research, online,
into what were the fastest rolling resistance tyres
and actually, some very fast clinchers, combined with
latex inner tubes were faster than the fastest tubular tyres. Now, I know a lot of people
out there feel like tubeless are faster, but don’t
necessarily have any evidence to back that up. The reason a lot of pros
still run with tubular tyres, is because of safety. If you puncture on one of
them, you can actually roll for quite a long time, and
of course on a mountainous descent with multiple hairpins,
you want to still be able to ride quite safely without
coming off, and clinchers aren’t so good for that. Next up, from Jorge Eduardo,
an aerodynamic position is useful on a climb, question mark. I saw Jan Ulrich use it on the two, 2004 Tour de France in
the Individual Time Trial on Alpe d’Huez, where he
had some clip-on bars. Well that depends on how fast
you’re riding up the climb. Jan Ulrich was probably
climbing incredibly fast up Alpe d’Huez, and once
you get over about 18 or 20 kilometres per hour, aerodynamics still has
quite a major part to play, as well as gravity and rolling resistance. So it just depends on how fast
you’re going up the climbs. Pier Juhng Hish, can super glue be used to fix tyre punctures? I tried it once and worked, but I’m not sure how long it can hold. At least it allowed me to ride back home. Amazing that you had super glue with you, but not a spare inner
tube to go in your tyre. I guess it does work, as
you’ve proven yourself. It’s not something that
I’ve ever tried, personally, although I think I might give it a go, just to try it out at some point. I know I have seen pro
mechanics that use super glue for the little nicks that
you sometimes get in tyres, to stop extra bits of
thorn, etc., getting in and puncturing the inner
tube, but now I will try that myself at some point. And finally, Douglass McCuiston
says, hello, do I need to change my front
derailleur if I’m changing my chainrings, using the same
size but different brand? And the answer to that is no. As long as the chainrings are
the same size, and they’re also round as opposed to some of the oval chainrings that you get these days, then you shouldn’t need
to do anything until it’s your front derailleur or,
indeed, the rest of your gears. Here’s a question which has been nagging Stephen Tovell for some time. What do soigneurs wrap
food in for the riders? Foil, parchment, or what? Well, actually, you’re pretty
close to the mark there. I did look it up a little bit earlier and we have featured
this stuff in some of our truck tours in GCN over
the past few years. They don’t use normal aluminium tin foil that you would use in cooking. I’ve tried that myself in the past when I’ve had nothing else at home. It does tend to get stuck
to home-made energy bars and to rice cakes, etc.,
and it’s quite difficult to unwrap, as well, in one
piece, which is not what you want when you’re in
the middle of the race. So, they get these packets
of eight-by-eight-inch parchment-lined aluminium foil boxes. You would’ve seen them, as I said, on GCN videos in the past. It’s just much easier to
unwrap, which is exactly what you want in a race. Now a soigneurs’ job is very interesting. They’ve got lots of tips and
tricks along these lines, which you might not normally think about. And many years ago, all
the way back in 2013, we followed Sophie from
Garmin Sharp, as the team was known at the time, to
see what goes into the life of a soigneur on a daily basis. – So we put two bottles, one of an energy drink, one of water. We have two bars in there, Clif bars, and then, one Blok. And then two gels, of our sponsor, Clif, and we add, a baby Coke. It’s kinda good today, good weather. And a fresh panini, we made this morning. The best part is right now at the feed zone (laughs) and massage, it’s good part, and the job in general,
is pretty good too. But the suitcases, I’m
gonna say is the worst one. – Our last question for
this week is from Rex 11. How do I find out if I’m
a climber or a sprinter? Somebody already answered it
for us, if you don’t know, then you’re a domestique, which is quite funny because
domestiques are generally people that are quite good
at everything, but don’t have one very specific strength. And it is quite easy to find
out what you are good at and not so good at, simply
by riding with groups or even doing races. You’ll quickly going to find
where your strengths lie. But you can also do some
testing in a laboratory or out on the open road with
the use of a powermeter. Four quick tests, which
include a maximum sprint test, a one-minute flat-out test,
five minutes, and indeed, 20-minutes, are going
to enable you to create a power profile. So when you compare those
test results to your weight, you’ll get a power-to-weight
ratio for each one, and then you can go onto a
site such as TrainingPeaks and you’ll be able to compare yourself to the very best at those
particular durations and find out where your strengths lie. But it’s not all about numbers. Take Mark Cavendish as an example. He never performed particularly
well in a laboratory, and there are loads of
people who’ve got way better sprint power than
he has, but he’s the best sprinter of a generation,
an arguably, the best sprinter of all time. Anyway, if you do want to find
out where your strengths lie and you have the use of a
powermeter, this next video is for you, because it goes
through exactly how to do all of those four tests. (funky music) – I feel I can safely say that I got everything out for myself and you only get that
one right the first time. That’s not something you want to repeat twice in the same ride. Okay now we’re ready to
start the five minute test. Now like the one-minute
one, if you’ve got a climb of five minutes in
duration on a steady grade then that would be absolutely perfect, but if you haven’t, do it
on a straight, flat road without any junctions,
and not too much traffic. – That’s it for this
week’s Ask GCN Anything. Don’t forget if you’ve got any questions which you would like us to
answer, you can leave them in the comment section below this video or on social media using
the hashtag #TorqueBack. Make sure you subscribe to
the Global Cycling Network if you haven’t done so already. You can click on the globe, which is somewhere on the screen right now. And then, you might want to watch one of the following two videos. In the left corner, my left, your right, just
down here, you can find a tour of the Katusha Team Truck from the 2016 Tour de France, where
you can see what the soigneurs and the mechanics have on board, and in the other corner
you can see Si and Matt trying to determine what the
best bike to use over cobbles: Cyclocross, road, or mountain bike.

  1. #Torqueback. Hi GCN my bike has a ratteling by the headset however i have checked my headset and it is tight enough also it has internal cable routing. Do you know what it could be? keep making great videos!

  2. How much of a difference am I liable to see moving from my vintage 10speed to a more modern bike? #TorqueBack

  3. hey GCN! i like the vids you make! first roadbike purchase is on hand, order a bike online (Canyon) or look around in local bikeshops for another brand? thanks in advance! #torqueback

  4. on races where flats are very common i.e. paris-roubaix why don't pros use tubeless tyres? or put sealant in their tubs? #TorqueBack

  5. Watts over aero but neither before skill.

    That is my saying. You need watts to be fast, then get aero, but skill with always prevail.

  6. Can you address tips for riding into head wind? Today was a typical beautiful sunny day in Kansas, with high wind speed at 31 mph or 49 KPH #torqueBack

  7. cycling weekly recently did a video of a 15 minute climb in vs out of the saddle at 300 watts. in the saddle was 2kph faster, but out of the saddle resulted in lower heart rate

  8. Idea for future video. Why should I care about wheel dimensions if it's the tire that's on the road? #Torqueback

  9. I spent a year in the UK with my family when I was 5. We bought my first real bike there and it was called a Chipper. Small kids bike version of the motorbike referred to as a Chopper

  10. Hello, why are you guys not following/covering track cycling? The worlds are right now and no word from you about it.

  11. If I change my chain rings into oval chain rings do I need to change the front derailleurs or just re position it ? #TorqueBack

  12. #TorqueBack I am doing my first multi-day event in June. It is the Dragon Tour in Wales, 3 days of riding. What would you recommend to do after each ride to make sure my legs are ready for the next day? Are there any specific stretches or indoor trainer activities I can do?

  13. I recently purchased a power meter and noticed that my indoor trainer power is MUCH lower than outdoor (about 50 watts for 20min FTP…). That is true across the board at different power range. Why? Any way to fix it? #TorqueBack

  14. Hey gcn I was wondering if you go faster with dura ace than ultegra if the awnser is yes then how much difference is it #torqueback

  15. #torqueback, has Dan never heard of Mario Cipollini? What's this nonsense about Cav being the best sprinter of all time?

  16. #torqueback what are the best media channels in English for keeping up with race news, particularly the world tour series? (internet, TV, YouTube, newspaper, etc)

  17. Hi im 14 and dont really have a cycling family. I have a track bike and rollers which is used for most of my training. Do i need to be training out on the road? #TorqueBack

  18. In answering the "what first bike" question, Dan has forgotten to consider the cost. Few people choose CX or gravel bikes to be their first because the price premium you pay for a little more flexibility is very high, and nobody wants to spend a fortune before figuring out how important (if at all) this cycling thing is going to be. Also, nobody starts out assuming they'll buy a second bike.

  19. Will you do more nutrition/cooking/recipes videos with team chefs this year, now that the grand tour are about to start ? #torqueback

  20. How do cyclocross pros collect all their power and other data given that they use multiple bikes in one race? Do they have a head unit and a powermeter on all of their bikes and if so, how do they combine this data to view the stats for the whole race?

  21. GCN, can you please give a a road racer or road bike. I really want to train and practice for the future race.

  22. I`ve struggled for years to find a saddle that`s comfortable after a 50 mile plus ride. I know that a saddle is a very personal item on a bike but how do you work out which width is right for you & is there a way on measuring it? (This is for a road bike).

  23. Any tips/techniques for breathing? I know I'm making hard efforts harder by not pacing my breathing. #torqueback

  24. #TorqueBack I've recently taken up cycling and as I begin to increase my ride lengths I have been getting quite a lot of lower back pain. Why is this and what can I do to sort it out?

  25. Im realitivly fit and average around 70miles a week but my question is why do I still get so many snot rockets and where do they come from? #torqueback #askgcn

  26. Instead of buying a maintenance stand for your carbon frame, you could make one out of an old Rotary washing line like I did. But it was never shown on hack/bodge of the week….

  27. #TorqueBack Ok i have an FTP question. I used to live in Switzerland and i had plenty of hills around me and my ftp was just above 250. I moved to Indiana, USA – mostly flat. My Garmin calculates my ftp for me and after a while here (9 months) it was down to below 200. Just recently (within the last few days) I was in North Carolina, riding up the Smokies etc so reasonable hills. My Garmin came back to me with an ftp above 250 again. I'm using a Stages power meter on the bike, so thats how the ftp is calculate, is my ftp not really being effected, is it all location depend????

  28. After a period of sickness and weight gain would you suggest your fat burning training or the longer endurance training sessions to get my fitness back?

  29. Hey GCN, how about time tagging the different questions? As much as I love the whole video sometimes I just want to quickly get to a specific question

  30. The outside of my foot goes numb on long rides, is this most likely down to my shoe for or clear position? #torqueback

  31. #TorqueBack
    How and when did GCN start? And how did you guys become GCN presenters? which were the first steps?

  32. Should I put bike bottle on down tube or seat tube?apparently seat tube more aero but more awkward to get bottle or should I invest in aero bottle and cage?

  33. #TorqueBack
    What is your opinion about Chinese wheels? Generally I Have heard bad things, but the company Yoeleo, seems to be allright. Have you heard about them before, and what should I be cautious off, when looking at them (chinese wheels),

  34. Is mtb allowed in tour de france? With Rigid bike 29er(XC) with the ratio of gears 53t and cassette 11t-25t (Rim brake)

  35. #TorqueBack…Why do professionals always have an 11-28 on their bikes??….How many races a year do they really "need" a 39×28??….I did see a bike you guys reviewed for Paris Roubaix that had a proper 11-23, for a race with no large hills. What's wrong with changing the cassette for races with "killer" hills???

  36. Q1: is it better to transport your bike if your going away for 2 years to another place or just buy a new bike on your destination then sell it before going back?
    Q2: if am going away for 2 years to study overseas, how should I keep my bike so that when I get back after 2 years it is still ridable?
    Q3: Which bike needs more maintenance, Carbon VS Aluminum VS Steel VS Chromoly specifically for RB?


  37. What are the best tubeless racing tyres for road riding? I would really like some 28mm and 25mm tubeless tyres to put on my racing bike but have never had tubeless tyres before and don't know which ones to buy. #TorqueBack #askgcn #torqueback

  38. Ask GCN. What is a race and what isn't? Delighted that cycling is so popular and each to their own but I do get irked by riders who do sportives and say that they're racing. The GFNY series and similar events are also a grey area. What do you guys think?

  39. I'm due to have reconstructive surgery on my ACL (knee…) so will be off the bike for a few months. Any tips for getting back in to it when I'm slightly more able-bodied? #TorqueBack

  40. If Froome and I would both climb at 200 watts for an hour (at the limit for me and a complete breeze for him) would we burn roughly the same amount of calories? #TorqueBack

  41. What kind of tape do they use on rider's in-ear monitor so it doesn't rip their ears off when they take it out ? Do they also have a mic to communicate to their DS ? #torqueback

  42. I cant understand when everyone says that its slower/harder to change out a disc equipped wheel. I have 2 road bikes which have discs. Other one has Focus' rat thru axles, which are in my experience faster to change out than standard quick releases. And the rotor "disalignment" is non-existant! #TorqueBack

  43. I'm 16 and very active and I have rode my bike and got 199bpm; 198bpm and 197bpm (top 3 that I had recorded) and I was wondering if this is dangerous or on the limit? #TorqueBack

  44. Why are all the GCN presenters men? Come on, suuurely there are some ladies who can get on the GCN bandwagon 🙂

  45. Is clamping my carbon bike on a bike carrier going to damage it? Are there any precautions i should take? #Torqueback

  46. Hello GCN, What is the Pros FTP average? And if your 35 years old and FIT, is it possible to reach such FTP? or it is a lifetime process? Thx #TorqueBack

  47. #TorqueBack It's always nice to be able to crack open a brand new pair of socks for a big event/sportive, but would you recommend doing the same with bibshorts? For instance, if taking on something like the Paris-Roubaix challenge where comfort is key, would you go with a boxfresh pair of bibs, or ones you've already "broken in"?

  48. #TorqueBack hey GCN thank you for all your vidéos, i will do my first Triathlon S size in 2 weeks, how to prepare my road bike for a tri ? Thanks !

  49. GCN #TorqueBack "Hi guys, how long can you spend Off the bike before your performance starts to suffer?"

  50. Just like a female might not need a female specific design, a male may find a female specific design suitable! I saw a picture of Arnie with a Liv MTB. Wish we could move away from non binary gender labels for bikes. Bikes don't even have reproductive organs 😉

  51. #torqueback if you brake too much on a downhill does the heat generated on the rim increase the risk of bursting your inner tube? How do I know when to let the rims cool down? How do the pro's manage this, maybe they don't brake? @@

  52. #torqueback when i come into the bottom of a steep climb fast, often I end up with not being able to find my cadence and torque to get a rhythm up the climb. I get better times when I approach it at a more moderate pace and get into a rhythm, even though I have less momentum. How do you manage sharp changes in gradient, especially when both gradients are quite long.

  53. 1. I want to change my rims with new, wider ones for 30mm tires. What would you buy: clincher or tubular (glued with tape, not glue)
    2. is it worth to add sealant fro. tubeless into tubular tyre?
