Visiting SRAM + Doddy’s New Bikecave | GMBN Tech Show Ep.37

– Welcome back to another
weekly GMBN Tech Show. Number 37 this week. Coming up on the show this
week we have some amazing news, but not too much about that for now. There’s a whole bunch of
other cool stuff coming up. So you’re gonna check
out my new bike cave. We go off to TF Tuned. You’re gonna see inside
the forks and shock on the bike build bike. And we’ve got an amazing
rewind story to tell you. [Whooshing] So first up in the news is
a slightly revised version of the Propain Rage downhill bike. The same bike, in fact,
as raced by Phil Atwill at the World Cup downhill races. Now, on screen now you can see a couple of different options of the bike. It comes in 27.5 inch wheels and 29. The 27.5 is available in three models, and the 29 is available in two models. And interestingly, the
29 is only available in sizes large and extra large. Propain feels it is not
appropriate for the shorter rider to basically get the benefit
of a bigger-sized wheel because there are too many small issues, i.e. tire buzz and things like that. Now it’s got a 63 degree
head angle upfront on there. It’s a full carbon construction. Really, really nice looking bike. But dare I say, it’s actually, I think, one of the nicest looking bikes
on the scene at the moment. Now the chainstays have
adjustable chainnstay length obviously to cater for different wheels, but also to cater for how you might want to ride that bike they’ve got a flip chip on them. Now interestingly,
there’s a reach adjustment on the front end of the bike there. So it’s a 12 mil, so plus and minus six millimeters of adjustment. So on a size XL, you get a
four four one, four five one, and four six one millimeter
options of your reach. So that’s quite a cool thing. And we have seen that, actually it was kind of pioneered by the Santa Cruz guys with
their headstock system on their bikes when I was testing out his double XL size frame. So chainstay of course is four four five and four four nine in those two different settings. Very adjustable and very
cool looking bike, I think. So next up is just a little bit more news on those Michelin DH22 tires we referred to back in
show 30 a few weeks back that we’d seen on Sam Hill’s bike. Now of course it’s a downhill tire. It’s not one of their Enduro tires. But we do think he might
be using their Magic X, which is their super soft compound rubber that’s notoriously grippy. Now Sam obviously is being
shed in the EWS on these tires, and he loves ’em. Now if you look on screen now, it’s a screen grab from
Cam Zink’s Instagram page. And he says they’re the “Baddest
tire you’ve never ridden!” Now increasingly we’ve seen
these appear more and more and they’re not yet on
the Michelin website, so we do think a launch is imminent. I for one, really want to try that tire. I think the shoulders
honestly look incredible. Michelin of course have a good pedigree in the sport of mountain biking. They’re famous for the old Comp 16’s which were later called the DH16’s and the Comp 24’s. Again, they were later called the DH24’s. Two of the most popular tires. And they were really, really
ahead of their time back then. So it’s going to be interesting to see how the tires have changed for Michelin so keep an on the scene for
Michelin tires coming soon. Now next up is news of
a new bicycle company called Trust Performance. Now although they haven’t
currently got a bike out, if you just look at this it’s
a holding page for their site. Now, personally, I’m really
excited about this because the three people behind this are proper industry heavy-hitters. So you’ve got Dave Weagle, who’s very famous for
the Dave Weagle link, the DELTA System. Lots of very good suspension
design and tech there. Then there’s also Jason
Schiers, who’s ex-ENVE. So he’s behind all the
carbon fiber development. And finally there’s Hap Seliga, who’s the founder of online
retailer Performance Cyclist. So you put those three
together in a mixing pot, I think you’re gonna see
something new suspension-wise is certainly going to be carbon fiber an very exciting looking. So lookout for this in the
next coming week or so, I expect you’re gonna see a very cool bike being launched. And next up is news about
the Saracen 2019 range. Of course, Saracen being a
brand as ridden by Danny Hart. Now first up, I want to talk
to you a little about the Myst which is a downhill bike. It’s now available in a sort of a wallet-friendly aluminum
build which is fantastic. Same geometry. Same sort of thing that Danny rides. And of course it is
available in the carbon in a couple of different options. So there’s the Myst, the Myst AL, the Myst Team, and the Myst Pro. So there’s various different options there to suit every wallet, but also there’s a 27.5
and a 29 inch version. They’re completely different bikes. It’s not the same with
different flip chips and stuff like that. Now the thing that’s
especially cool about these is they are the same bikes as ridden by Danny Hart and the World
Cup Madison Saracen Team. There’s no different. They’re not riding a fancy version. They are riding the production
one that you can buy, so that’s a really, really
cool thing from Saracen. Now next up I’ve got a couple
other cool bikes, as well. In particular, is the Mantra. And that’s what’s on screen now. Now, that Mantra LSL stands
for Long, Low, and Slack. It’s a hardtail. Runs 130 mil fork, 27.5 inch plus tires. It looks really cool. But actually, the one I
prefer is the kid’s version, or the youth model. And that’s got 26 inch wheels, so it’s making use of all
our 26 inch componentry and stuff that we’ve had for so long, but actually finally putting it on a really good bike intended for kids. The whole bike looks fantastic to me. It just looks great for, no, as a matter of fact,
it’s not just kids, just anyone on the smaller side. Making the most of a
really well-designed bike. Now the last one up from
Saracen is the Traverse. Now Traverse has always been
a model in the Saracen range. Lots of friends of mine used
to have those in the mid 90’s. But thankfully this is
a lot better than that. So it’s a 29 inch wheel bike. Runs a 100 mil travel out
back and 120 up front. It very much seems to be the sort of the new fashion creepin in with a trail bike with less travels. So it’s basically got
the cross-country travel, but it’s designed to be
a bit harder hitting, a bit more sort of robust
whilst retaining that agility. So it’s a single pivot. It is linkage driven. It is really playful, and it’s got boost. I think this is a really
cool looking bike. It’s nice to see Saracen staying really up to date with things. Now finally last week
I popped over to SRAM for a meeting about some cool stuff we’re going to be making with them soon. And I just took a few pictures. We weren’t really allowed
to see too much over there cos they’ve got serious
prototype stuff on the way. But we did have a little
snoop around the factory. And it’s very cool. So, on screen we’ve just
some of the shots I took on my phone while we were there. And in particular, I
was blown away by seeing where the SRAM cassettes come from. Now, of course they are very expensive, but for good reason. They all start life as a
lump that’s over four kilos. Absolutely massive lump
which is cold forged into a bell shape before it is machined into what you and I know as cassettes. Now of course that’s a big lump of steel that’s machined right down. It’s very, very intricate. And then of course there’s
the aluminum upper sprocket which is just a work of art. Combined with two pieces together with that XD driver body. And it looks amazing. And it’s really cool to
actually see this process happening while we were there. And you can certainly see by
how labor-intensive it is, just how expensive they are. And I actually, I think it was cool kind of all brought back
into sort of relation there. It was also cool to see
the different generations of the original XX1 derailleur. So on screen now you’ve got the original boxy sort of mock up,
I guess you’d call it. Then there’s the first sort of prototype which was a usable sample, and then, as you can see, it
refines all the way through to the production option there. There’s something else
that caught my attention was an old cabinet from the Sachs days. Sachs is a company that SRAM ran actually in their old factory now, and of course Sachs was one
of the biggest employers in the town of Schweinfurt where SRAM are based in Germany. And in fact Schweinfurt are
actually really famous for being the ball bearing
hub of the world, really, so that’s where ball bearings came from. And as such, in World War II actually, it was bombed heavily because it would have had such
a dramatic effect on production of machinery
that used ball bearings. But anyway, so also looking through that cabinet of cool old stuff in it, I spotted something that looked to me like an electronic drivetrain
from Sachs, and it was. So it was Speedtronic. I do vaguely remember
seeing these years back. It was 1994 when they first came out. Had to go back and do a bit
of homework to find this out. It was a seven speed electronic
shifting system from Sachs. Of course it didn’t really go anywhere, but it just goes to show
that whatever’s going on now it has been done before. It has been experimented with. They just really didn’t
have the technology. And as we’ve seen on Nino Schurter’s bike, there’s some very cool
stuff coming from SRAM. And finally we’ve got have a little look at the huge SRAM tech truck. This thing is so cool. It’s probably the ultimate
bike haven of the world cos you can be driven anywhere. And at some point soon, I’m gonna have a look around in it, give you a very cool truck tour. So keep an eye out for that one. Okay, so now it’s time for Bike Cave, and as I promised last week, I’m just gonna throw you
to myself this morning. I’m gonna just gonna apply the coffee. Now, you’ll have to excuse my tired eyes. A little tour around my own bike cave. Welcome to my pretty
much finished bike cave. I’m quite happy with this now. We’re living in a house at last. It’s taken a couple years
to renovate this place, build this entire part of it
which I’m pretty proud of. And the workbench itself
you’ve pretty much seen. It’s a bit of a utility area, as well. I’ve got the washing machine down here and a sink also useful
for cleaning bike stuff, although I’m not sure my wife’s
gonna know about that stuff. Above the counter here, I’ve got this really cool
picture by John Tomac. Well, it’s sort of John Tomac in a race, and he signed it, “Doddy, Go Hard! Tomac.” Super proud of that because Tomac was always like an idol
of mine growing up. And also here’s my
custom bike, the AD 160, which was built by Jeff Steber. It’s my geometry ideas on end, and Jeff custom build it for me. In fact, that’s the bike right there. I will actually take that out, and I’m gonna give it a clean. It’s got pretty soft tires at the moment, so it needs a bit of love on there. But I’m gonna bring it back
to life and show you guys cos it’s a pretty trick bike and it’s way ahead of its
time when it was designed. Obviously I’ve got tons of
tires all stacked up here. Got the mud tires there
ready for the British winter. Got my tool cab, cables,
I’ve got all that stuff. That needs a massive sort
out because that is not good. But over this side, I’ve built this unit to specially house all
of my cycling clothing. So, it’s all stacked away
nice and neat inside, no. Neat-ish anyway, inside there. Got my GMBN jerseys and stuff. Used to be a red locker,
and I repurposed it. And also, I used the
last bit of my worktop just happened to be the perfect size just to fit all the
way along the end here. Alright, there’s a bit
of a gap at the top, but that’s a single piece
there, that’s pretty good. Got my helmets hanging up on there. That door goes into the house. I’ve got some helmet
hooks on the wall here. Kind of useful. Riding packs and stuff hang out there. Of course my Park work stand and my trusty Topeak Joe Blow Booster. That’s pretty much everything I need to work on my bikes and enjoy myself. So pretty sweet spot, but keep
sending your bike caves in. I love what you guys are doing. Honestly, it’s one of the
coolest sections of this show. I’m pretty sure the Dirt Shed
Show is quite envious of it. So keep ’em coming in. And don’t forget to use
our uploader service. The link to it is on the screen right now. It’s super easy to use. And there’s also a click through link below this very video in the description. Really easy to take those
pictures of your bike caves. Don’t forget to let us
know all the cool details so we can read them out
on next week’s show. Get ’em in guys. Now it’s time for Rewind. And this week unfortunately
I’m not going to be showing any of your guy’s amazing entries. We’ll make sure we go
XL on that next week. But I want to give you a
little bit of a lesson on something so cool this
has even blown my mind. So the bike on screen now
is known as a Yeti C-26. It’s a very, very rare bike. In fact, there’s only seven known bikes completed in existence. Now the reason this is so cool is because this particular one is little different from the main story. I’ll get there in a second. So originally this was
built for John Tomac. This one here is a replica. And Juli Furtado also raced one of these at the 1990 World Championships. So the frame itself is got the Yeti F.R.O. sort of basis to it. It’s got the curved seat and
chainstay loop at the back. They’re very famous for on there. And of course you can
see the drop handlebars. You can see those carbon main tubes and a whole bunch of other
amazing stuff like that. Shimano XT seat post. Did you even know that
Shimano made posts back then? Super, super rare stuff on there. Of course there’s a Tioga disc drive and a whole number of other amazing stuff. I think you’ll agree, it’s a pretty special looking retro bike. The thing that’s really,
really cool about this, so the name, the Yeti C-26,
comes from the designer of this who’s name is Chris Herting, so that’s the C in it, and he was 26 years of
age when he made the bike, hence the C-26. So, that’s the first cool thing. The second cool thing is the
face that the tube tolerances between the steel lugs
and Easton C-9 alloy carbon kevlar and carbon
fiber-wrapped tubes were so tight that when
they bonded it together you were never assured of
of enough bonding agent, or glue actually, being on the
tube to make that connection. So as they re-do the rest of the frame as they were building it, they could never be sure how
strong the frame actually was. And rumor has it that John Parker, so Mr. Yeti in those days, thanked God the entire way home from those World Championships just for the fact that Juli
Furtado’s bike did not break. And as soon as he got
that bike back to Yeti and retrieved all of the other ones the whole project was scrapped. So even though there was enough tube sets to build 50 bikes, only seven were actually produced. But the cool story is
actually what happened to the rest of those tube sets. Now, one original frame sold
for a remarkable $12,000 to a German collector on eBay. So it’s kind of no wonder
that something else didn’t really happen to these. And this particular bike has
got a quite a cool story. So there’s a collector
called Kevin Miller, and he’s quite a known collector
on the Retrobike forum. If you’ve never heard of Retrobike before, I urge you to check it out. It’s a very cool site. They’ve also got Facebook
and Instagram handles there. So check that out. The link to that is in
the description below this week’s tech video. Now he was desperate
to build one of these. And he somehow acquired some
of these original C-9 tubes from an unknown source in Durango, so some of those original tubes basically, and he also acquired an
original Yeti F.R.O., so For Racing Only frame, which he was going to use as the donor, in which case to cut the main tubes out and have these other
tubes bonded in place. So he sent that frame to Chris Herting, who basically built the original ones, and Chris turned it back
into an original C-26 frame. So it’s a reissue, but using
the original components. So it’s basically like a replica. And then it took him
the following two years to source all of the stuff on it. And just look at this thing. It’s mind-blowingly cool. Two years to get all that
stuff and build this bike. It’s a very, very special bike. And now it’s currently
living at Silverfish UK, and it’s owner Darren Mabbott, who if anyone knows this guy, he’s got a collection of Yeti bikes. In fact he’s got a couple of
Mammoth Cycle San Andreas. He’s got loads of cool stuff. I absolutely love the
story behind this bike. The amount of effort it
took to recreate this thing. And I can see why it’s
Darren’s pride and joy. I just want to say thank you to Darren for lending us the bike to
enable us to get these shots, which I think everyone will
agree, the bike looks unreal. So once again thank you to Darren to sending that bike to
us so we could get that. And thanks for all the
information about that story. Truly, truly brilliant that. So if anyone out there
knows of something else equally as amazing or
dated and retro as this, then let us know because
I think we’d like to do some more content like this. So maybe some longer form content, too. So, hit us up at the usual address, and of course, use the
uploader if you send us a bison to us. Use the hanshtag #Rewind, of course. Alright guys, now it’s time for Top Mods where you guys get to
send in video footage, photos, and stories of all
those cool modifications you’ve been making to your bikes. Whatever they are, even if you just changed the chain, take some pictures. Tell us about it. How was your experience? Was it good? Was it bad? Did it cost you a lot of money? Did it take you two days to do it? Whatever it is, send it in. We love hearing how you
guys work on your bikes, how you improve your bikes, and how you make them a bit
different from the others. Don’t forget to use our uploader service. The link is below this video. It’s super easy. Get your stuff in. So first up this week is from, um, An? Is it An? Is it an Ant? I don’t really know. It’s just A.N. “Hi, I’m from U.S.A. This year saw my bike go from rigid to hardtail to full suspension. I don’t have the money,
the room, and the time for another full bike, so this is the best option.” Right, so check this out. So in the first picture you can see a Surly with, well, there’s a hardtail setup at the moment, 29 inch wheels on there. Looking pretty trick actually. I do like those Surly’s. Nice low slung, quite
aggressive looking bike. And then the next shot, it’s turned into a Santa Cruz hardtail and the Surly’s up on the workbench there. So that’s pretty cool actually. He’s just basically
doing a full frame swap. So I guess maybe you might ride the Surly in winter conditions and the hardtail in summer, perhaps? Not really sure. But either way, I like
what you’re doing this. That’s cool to have
kind of a modular setup you can move around. Is that the same seat post? If it is, that’s super cool that you’ve literally managed
to get the good combination. He’s got the same cranks on there. The same wheels. Same forks. Same bar position even, it looks. That’s a good attention to detail. I really like that. And I do like your workspace,
as well, by the way. I like that you’ve got a bench
mounted work stand there. Got a nice Salsa. Is that a road or a cross bike? I can’t quite see there. But it looks pretty cool either way. So thanks for sending that one in there. Next up is from CJ in Adelaide, Australia. “I saw the video and loved the idea, so I used an old ice cream container to make the tongue guard. Keep up the great videos.” Nice, okay, yes, you made yourself one of those front mud guards
using a bit of a milk bottle, or in fact, an ice cream container. You just said that. I don’t why I said milk bottle. That’s cos I made one out
of milk bottle, I guess. And you’re using hashtag
#GMBNTECH, hashtag #GMBN. Always good to see. Nice one CJ, thanks for sending that in. Good work. You’ll also like this one. The next one is from Ben in Chepstow. “This weekend, I tried
a new maintenance job and revalved the damper
on my X-Fusion Sweep RL2. Like many others, I feel
the standard fortune doesn’t have very good
small bump compliance. I’ve been running with lower
pressure to compensate, but it’s a bit divey on the techy stuff. But shifting the second shim in a stack behind one of the small pivot shims, the early or low force
damping is reduced slightly. Even as this simple change is my first go at proper internal suspension tuning, some keen to see with the difference, and see what else I can
do with the shim stacks.” Now that’s a really cool
way around that, Ben. I see I need to consider
some stuff around myself. I like what you’ve done there. And yeah it makes perfect
sense that that shim, flipping it the other way around would just narrow it to
break away a little bit more. Good work. Nice selection of images, too. Always nice to see that. So thank you everyone
for sending those in. Some really good, top mods there. Keep ’em coming in. We love ’em. Alright, and now it’s
time for Tech of the Week. And as you can see here, we’ve got a few bits
and pieces to show you. So there’s a new Nukeproof bars here. These are the Sam Hill editions. They come in three different rises. Let’s just have a quick
look through these. So this one is the 20 mil rise. So full, 800 mil width. And as you can see by the cut marks here, Sam runs his at 750. Bang on. But I’m gonna run these at full 800. Like I said, there are three
different rises in these. There’s the 20. There is, bear with me in here. There is the big boy, which is a 38. That is the one I’m gonna run cos I really like a high
bar to roll them forwards a little bit more to try and get a little bit more reach out of my bike. And there’s a slightly lower one, as well. All of which look super cool. I think you’ll find very
nice looking bar there. And it has Sam’s personal
sort of twist on there, too. But there’s also the stems. So I did show you the
prototypes or stages of these a couple of weeks back
when we had those renders and we’ve actually got
the stems in the flesh. They come in three sizes. They come in 60. They come in 50 and 35. So that’s the 60. And they come in a range of colors. They come in red, blue,
black, and my favorite color, in fact the rest of these are
almost irrelevant in my eyes once I saw this other color. The red and black I think you’ll find do look really, really cool. And I know Dan Dan the
cameraman has got his eye on the red one to go on his nice new Orbea. But it’s all about this one. As far as I’m concerned, the copper. That is the most badass looking stem I’ve seen in a long time. 35 mil, that is the length I like to run. I think that it’s absolutely gorgeous. These retail for 59.95 and are available about
now, as far as I know. Super, super nice bit
kit from Nukeproof there. So there you go, there’s
three different bar options, three different rises, four different colorways in the stems, and the three length options there. So stems, about 60 quid and the bars, about 55 quid. Although, pretty sure you can
get ’em a little bit cheaper if you hunt around online. But nice, good, simple series of stuff. Good kit. Alright, now it’s time for Bike Build. Now earlier on, we went
over to TF Tuned Shocks. They’re an official suspension
tuning service center in the UK. They’re also a distributor for Bike Yoke. So went over there. Take the bike build over there. Okay at last we’re over
at TF Tuned Shocks. I’ve got the bike build shock
and fork in my hand here. This the bad boy here. Just taking these off, and Finn is going to be
the guy working on them. I think the aim is to make the
shock a bit more progressive, but more importantly, to make sure the fork matches that system of balanced feel, front and rear. Now let’s see what Finn
has to say on that. – I think that’s what you’d
expect from a brand new shock. – Yeah. No volume spaces in there. – [Finn] No volume spaces there. Standard, so we’ll change that. [Laughs] – So, first stop, Finn
basically took apart the rear shock. And although there there
was nothing wrong with it, he filled up with the biggest
volume spacers on there cos the way I would want to
ride that bike is quite hard, and I want it to feel quite progressive. As it is, it felt fairly linear, so we’ve gotten that to ramp up nicely and he put all new lube in there and loads of it, too. And he also changed the little valve core on the inside for what I say is a slightly more reliable one. Because sometimes you can
damage those with shock pumps, and I’ve done that in the past. But something that was
really cool that I saw there that I’ve not seen done before was the way the shock
was charged up inside. Now they had these special machines. So Finn is just about
to charge the pump up. Normally, well you can
do this with a syringe, but then often I’ve
seen this system before. Just tell us a bit about this. – This is an Andreani. It’s a vacuum bleeder, basically. So what it is does, it creates
a vacuum inside the shock and does that for about two minutes and then it’ll switch over
to a positive charge and it fires the oil in.
– Fills the shock up. – Fills it up. It’s nice and quick. And it ensures that
there’s no air bubbles. Cos what can happen is with the shim stack and with the piston. The air will sit inside that piston – You can get entrapped stuff. – So if you’re doing it by hand, you can only cycle it slowly by forcing the oil through there blows all the air out
of the system basically. – I guess the advantage working
with something like this is that you can plug that in and you can go work on something else while it’s doing it. – Yeah, I can plug this in, and then obviously if I need
to change the air can seals, this will sit there, do its thing, five minutes later come back to it. – [Doddy] That’s cool. – And it’s ready to roll. – Got three of ’em. The shock was put back on the bike and instantly just felt slightly smoother. I think it’s just, you know, fresh lube. All that sort of stuff. It’d been sat there not doing
anything for quite a while even though it was a brand new shock. The fork was the
interesting thing, though. So, TF Tuned were actually very, they praised the damping
system on that X-Fusion. They say it’s actually
quite a lot of good range of adjustment in both high
and low speed compression. So it’s really down to how
the fork’s gonna be ridden that defines the setup, but I wasn’t quite happy with the breakaway force on the fork. I wanted it to feel a bit more supple, and I also wanted it to ramp up more. Which of course that’s what
downs to the air leg on there. So, Finn stripped the fork down and had a good look at the inside, and something that was
immediately apparent was the air tube at the
bottom where it slides into the stanchion tube and into that sort of the air chamber. There’s actually quite a
bit of stiction with that and a bit of a knocking in the first, sort of, initial part of the movement. And we can actually wiggle
it around within there and you can feel it almost binding. [Inaudible Chatter] – [Finn] Quite often that can
be due to with the lubricant, although it’s got what
looks like something similar to red rum in there. It’s quite thin. A little bit watery. Let’s see what’s going on. – Now as he took the whole system apart, it was quite clear the part of the design it’s a rod that goes into
like a little ball joint to enable it to move, I
guess, if the fork was binding and it would allow the air tube to consistently move up and down the fork to continue working. Which I think we agreed was
really smart way of working, but the actual ball joint
itself had movement in it and the quad seal around that had quite a lot of stiction to it. So, while it was a very good
quad seal, it was very dry. So we sorted that out. We put a load of fresh
grease around there. And he put some different o-rings in there that got rid of that initial
sort of knocking movement. And literally, even just
cycling that air tube on its own into the stanchion tube you could see the fact it was it had such little friction compared to what it did to start with. And then, because of design of the fork, there wasn’t really any compatible option for volume spaces in there, but because it didn’t
have a negative spring, it had a coil negative spring on there so quite old school, but really reliable so it’s quite a good system. In modern forks, you
need air volume spacers and the reason you need those instead of putting oil in that chamber, is if you put oil in the chamber to raise the oil higher and change the air volume space in there, the problem you have is
the oil clogs up the ports between the positive
and negative chambers. Basically, it can’t equalize and it would never work properly. But because this fork had the
coil spring system in there, he covered in heavy-duty grease and then put it back together and then before we put
the air cap back in, I think we put 10 or
15 cc’s of float fluid in there to really make
the fork ramp up a lot more towards the end of travel. And put the fork back together, doing the weight test on the bike and it felt amazing. It feels really, really well balanced, front and rear, which is exactly what I
wanted the bike to feel like. So I’m super happy with that. And of course it bears a
couple of TF Tuned stickers, which any fork or any shock
that goes through there gets that sort of seal of approval once it’s been fully tested afterwards. Just a really cool process to see and see how those people are constantly churning these out everyday. Something else that was also quite cool that we didn’t capture on film just because of sound reasons is the fact that those guys as they’re working on the
forks and shocks there, they’re wired in, as well. They’re chatting to
consumers and customers and telling them how to solve problems with their own stuff at the same time as they’re working on stuff. And the stuff that all of
the technicians know there is second to none. It’s absolutely amazing to see ’em work. So now finally the bike
build bike is finished. So I’m gonna take it out this week. I’m gonna shoot the bike so you can see all of it in its nice, or its
natural habitat really. I’ve got a very cool
place I’m gonna shoot it. I’m gonna tell you a bit about the bike, and you’ll find out what

  1. Cnc milling/lathe is a labor intensive process? OMG! what a bunch of avg joe nonsense…. the Cassettes should be super cheap because it basically is mount/fix the material inside the cnc machine push the button and wait 10 min before it is finished. Honestly modern machines does not need any manual fixing of the one pice material as it can do it itself and then when it is done replace it with a new one… Omg I know I sound like a grumpy old man but you sound more and more like you want to make everything out to be so amazingly hard to make and expensive… What you are talking about was the norm back in the late 90s early 2000…

  2. any fork /shock maintenance vids would be cool. Oil levels, inspections and seal replacements. Great to see what goes on behind the scenes and all the attention to detail they go to.
    Lots of awesome content.

  3. in amazon you can buy a 35mm stem for 8€ here in spain, i have it in my bike and works very well, im not going to pay 60e por the same thing.

  4. Hi doddy, I always think who’s is the best mechanic you or Jon from gcn? What about a mechanic challenge between you an Jon? Think about it!!!!

  5. Was checking out a vid on an audio interface but had to blow it off when I saw the chez Dodd bike cave was up and running! Top work Doodles!!!

  6. Hi doddy my tyre was rubbing on my frame and I just thought this would cause paint to come off and tyre to wear but it seems as thought the tyres eaten through the metal, is rubber stronger than metal

  7. i have video fotage of my bike crash from when i was hit by a car i have pics of my cross country bike before and after as well as pics of my injuries on my arm and leg i can provide the full doscription to of what happend so is this somthink gmbn would be interested in to show on a show #askGMBNtech #askGMBN

  8. Grew up and went to school with Darren who owns the Yeti, he was 2 years above me but same year as my brother who was mates with him and I was good mates with his little bro. Remember him going on long road bike rides while at school and really getting in to his bikes but has no idea he'd turned his passion in to a great buisness. Brilliant to see he's done so well and brings so much to a past time I love so much myself.

  9. Awesome Yeti story, Doddy. Like you, I grew up watching Tomac race and saw him at least a half dozen times at NORBA events back in the day, primarily at Mt Snow, Vermont and another course down in the Catskills in NY.

    Never got his autograph [great cave btw!] but scored a Volvo-Cannondale team poster in 1994 with autographs from Alison Sydor, Sara Ellis, Tinker Juarez, and Marc Gullickson. Tinker was a wonder to watch but nobody rode with finesse like Johnny T. When I pull the poster out, I'll take a pic and send it your way. Love the show- keep up the great work!

  10. 9:45 I am guessing where you live, it is not very safe considering the way you have your bikes locked up. Thats sad you can't feel safe in your own home.
    Awesome you were able to get a bike made to your liking. I wish I could have got My Specialized Enduro with a lower seat tube and slightly steeper for better climbing, and a wider chainstay to fit 3.0 tires.

  11. #askgmbntech I have a Scott aspect 740 2017 model.
    Is it alright to add a 120mm fork to it. Aswell do you have any upgrade suggestions for the bike that will make it feel more aggressive 👍

  12. GMBN Tech is by far my favourite GMBN subsidiary of the brand along with anything Blake does Haha. Keep travelling, exploring and adventuring to different places. Keep digging for amazing tech both upcoming and old. Educate and continue to showcase what’s out there!

    Peace out my dudes and dudette (female presenter).

  13. Nice show, as usual. I didn't find the name of the bike in 26" by Saracen on their website, could you help me, I've a shed full of 26" wheels and stuff like that 😉

  14. what about doing a say 700 quid(or whatever you guys think would work best) build challenge between you and another gmbn presenter and then have us vote on who built the better bike?

    I've seen other non-cycling channels do this and it's very fun to watch

  15. The 2016 Mantra is what made me start using MTB again. Borrowed it from my uncle for a few weeks, then went out and bought a Trek Roscoe 8 2018 😀

  16. Doddy, I'd love to see a video of the process of forging and machining the Eagle cassette start to finish. (speeded up of course.) You showed a couple of the steps in this video but I'll bet it would be super interesting to see it all.

  17. Great show, loved the retro yeti, I was there for the world series in Plymouth back in 1994 and met tomac too, what a legend, that was a really good weekend, the band in the evening was class, the Coors lager sponsorship wasn't good,so the only beer you could get, the worst hangover I've ever had, and I've had a few

  18. #askgmbntech I am working on a budget GT hardtail. Its has a Shimano Altus 8 sp derailleur and single ring up front. When in its highest gear, and pedal backwards, the chain drops down a gear. Replaced the derailleur and straightened the hanger and its still happening. The chainline looks pretty aggressive when in its highest gear. Is there a simple solution that I am not thinking of? Thanks in advance.

  19. Hi Doddy, love the bike cave! Question: is it really safe to hang bikes by their wheels (i even see some people hang their bikes via their front wheels)? I’m afraid it might put unnecessary strain on the fork and/or the frame, though I see a lot of people do it. (And sorry to ask this: is this safe for road bikes also? Please forgive me for that question.) ✌️

  20. could you please make a tutorial on how to strip the paint of an alu frame?( what product to use etc) and then the best way of painting it again.

  21. Nice Mission Workshop camp backpack. Mine is about to see 3rd Oregon winter rain season.
    Built really well. Great vid, Doddy.

  22. on the old school section, usually i think old bikes are ugly as fuck, but the back story to that bike made it into and absolute work of art! plus it looks soo different to anything else i've ever seen. extremely interesting for younger mountain bikers+mechanics like myself.

  23. What grease did TF tuned use on the negative spring? If my shim stack tweak doesn't sort the fork then I might try the volume spacer oil trick to increase ramp up. Thanks for featuring my mod this week by the way!
    Also, I've got an old set of dual-air Revs on a bike that pre-date volume spacers. They have a separate -ve air chamber so is it safe to add oil to them? I assume there's no port to block between the two chambers. They're in desperate need of a bit more progression.

  24. #askgmbn #askgmbntech Hi guys! Love the show. I'm looking into getting my very first mountain bike that's not from a department store and am stuck between the Trek Marlin 7 and Trek Roscoe 6. I have had my eyes on the marlin for a while but I'm not sure whether spending the extra on the Roscoe (as it has a 1x compared to 3x drivetrain on the marlin) is worth it. Or should I just buy the marlin and convert it to a 1x? Appreciate your answer and thanks in advance!

  25. Great vid
    Love to see you going places and getting out I find it more interesting when some goes to a factory/shop like that

  26. I have updated my Fatboy specialized SE 26 tires by 4.8 from 10 speed to 12 speed and I got that Granny 50 cassette I'm a big guy I'm 230 lb but already has my ability to use the gears at Schramm give me and that's Fram Eagle NX there's not a hill around Cortez Colorado that I cannot make it up unless I'm just out of wind and I'm 55

  27. Yeaa men is the bike is mej jams equipad for decsender donwihll bikes algu desco the marc in the mercad nasciona of the paid for son ryalment good men. from the Santig of Chile 🇨🇱 🤣 💯 🤘 😀 👍 1⃣

  28. Hi doddy is it about time you sorted your hair out as it’s looking a bit greasy as they say are you washing it or putting a full container of hair gel on each week because it looks way too greasy to look at every time.

  29. Sachs was always ahead of its time. I rode a Sachsonette, a motorized bicycle in the nineties, way before it was cool 😛

  30. SRAM: They're expensive because robots make all the things …
    I don't think that's how robots are supposed to alter pricing .. 🤖😆
