The Future Of Mountain Bike Tech At Eurobike 2018

The Future Of Mountain Bike Tech At Eurobike 2018


– So we’re here at Eurobike 2018. This is at Friedrichshafen It is the biggest trade
bike show of the lot, and we’re gonna check out all
of the new, cool tech stuff. (smooth, chill music) Now, this is a pretty
interesting bit of tech that I’ve been meaning
to try for a while now. Just kind of forgot they’re around. They’re called the Vibrocore Handlebar, and they’re from SPANK. They use a similar technology
to a lot of Motocross bars. They actually have an insert
on the inside of the bar that is designed to sort
of reduce that fatigue that you get transmitted
through the handlebars in the form of vibration to your hands. Really interesting concept. Think about it in a way that
you get a big echoey room, and you can absorb that
sound using egg cups or foam. It’s gonna be a similar sort
of principle with vibration by having that core on the inside. Really cool concept. I need to try some, I think,
to see what they’re like. So we’re here on the Northwave stand, and we’re really pleased to
see that in addition to all their super high-end,
aggressive cycling shoes designed for the world of clipless pedals, they’re now making flat-specific shoes. So it’s the Tribe and the Clan. I’m just gonna take you through a few of the cool details on these. So we’ll look at the Clan first. So it’s three colorways.
There’s the all black. There’s the black and gray. At the top, there’s the blue and black with the orange detailing. Now this is a three-part sole,
and it’s a completely unique sole to Northwave. And they’ve worked in
conjunction with Michelin to develop this. So the tread pattern itself
is one part of the sole, and that is their Gecko Plus Compound. It’s the softest compound,
and it’s got a lug design at the front of the shoe
and at the back of the shoe for the hike-a- bike stuff. And the mid part of the sole is designed for maximum purchase on flat pedals. It’s a very aggressive design. So the middle part of the
sole, as you can see here, this gray part, that’s TPU
rubber, so it’s urethane rubber, and that is the shank of the
shoe that gives it a very, very stiff and supportive action. So it’s dedicated cycling
shoes, not just a trainer with a sticky, rubber sole on it. This thing is designed to be
really good on flat pedals. It gives the rider support,
not too much on there. It’s got a nice amount of
flex, so you can feel the pedal through the sole of the
shoe, but not too much that it becomes uncomfortable. It’s a very efficient shoe to ride in. It’s got loads of toe flex
for off the bike stuff, so it’s gonna be quite
an intuitive shoe to use. And, finally, there’s
the EVA cushioning layer, which makes it very
comfortable both off the bike and, of course, providing
impact protection on the bike, and, of course, against
vibration, which you get a lot of on any sort of riding. So it’s a very comfortable shoe. The upper on it has got
lots of ventilation on here. The padding on the upper
isn’t so dense that it’s gonna absorb water. There’s just enough there,
but it’s very light-weight. So it’s actually gonna dry very fast, which is great for us riders in the UK, and there’s lots of mesh on there. It’s TPU welded as well, so
it’s a single-piece design, very clean bit of kit. Really quite into that. And, of course, there’s also the Tribe. So there’s five different
colorways in this shoe available. Just gonna hold up the gray model here. Now this has got a slightly
harder compound rubber sole. Of course, this one isn’t
quite designed to be as high-end as the Clan shoe. This is more for your day-to-day shoe, much more like a skate-based trainer. So you got the nice heel-box in there, the nice toe-box on there, and a bit more of an aggressive sole on this, so it hooks up really
great on and off the bike. Also, they look pretty cool just to wear with a pair of jeans. Now, the Outcross is one of
my favorite models of shoe. This is a shoe that I use
in my day-to-day basis. I’m a clip-in kind of rider
mostly, so as much as I love the flat-pedal shoes, this
is really where I’m at. Now this is a slightly revised version. It’s got improved Velcro straps on here. It’s still got the dial on there. It’s a really good shoe,
but I’ve also noticed they make a super
light-weight version of that. As with all of the Northwave shoes, they’ve got Michelin
rubber soles on there. It’s a really good sole off the bike, loads of stable support there, and it’s a nice, wide heel on there. This has got a super light
fly-mesh upper, and it’s got a nice gaiter system on there as well. So it doesn’t weigh a thing. It’s such a light shoe, but it’s got a really tough, sturdy sole. Again, it’s got a nice, protective toe-box and heel-box on there. Really good shoe. In fact, I’m
gonna have a pair of those. So a little bit of new technology here involved in the world of locks. So this is the Hiplok Airlok. So this mounts to your wall in your house. It is also a place to
hang your bike, but also a place to lock it so
it’s absolutely secured. Now as you can see, the
unit is actually locked, but using a dedicated app,
hit the unlock button, and you can pull it out. So basically you’ve got a
balled design here in the end while using the app. That is super cool. Of course, this is at concept stage. That’s not a real iPhone at the moment. This is just a mock-up
of how it’s gonna work, but this is retrofittable
to the Airlok system and their forthcoming
ground anchor system. Now what’s the point of this? Well, perhaps you locked
your bike at home, and your wife wants to take it for a ride, or something like that, and you don’t have to share the keys. You can just unlock it
or lock it using an app. Maybe it could be used for
bike sharing in public, for hire bikes. There’s a whole world
of benefits to be had from a bit of lock tech like
this, but I absolutely love where this is going, love seeing
all this cool concept stuff at shows like Eurobike
that you wouldn’t see unless you asked about. Very cool. Just gonna unlock that, (lock snaps) and lock it. Now this is the next
product you’re likely to see coming from Hiplok. This is another orientation
of the popular Airlok, which, of course, is
that wall-mounted unit. Now this could be mounted on
the ground as a ground anchor or on the wall, or even both. Now this could be quite cool. I’m actually thinking
this might be a good idea for my own workshop,
mount one on the wall, daisy-chain all the bikes
together, mount one on the floor, lock that daisy chain to the floor, so it’s a really hard job,
hopefully, for someone to get the bikes out if they do
manage to get in there. Love a decent ground anchor system, and I love where this is going. Great tech. So this is a little bit of
a hint of what is gonna come from the future. And I think this might
happen for all bikes, but Magura are here first. This is a concept set of handlebars called the Cockpit Study. The concept actually comes
from old motorbike stuff with housing they used
to have back in the day, like fairing, covering up the cables. The cables would be entirely
internal on the handlebars. There’d be a bleed port on
the end of the bars there. How neat and tidy is that gonna be? A whole cockpit bar and stem,
integrated brake levers, no cables or anything. I think that’s gonna be
an amazing piece of kit when this hits the shelves. And yet another piece of
really cool tech from Magura, heated grips. This is something I have
wanted to see on mountain bikes for a long time, and of course
with e-bikes having a major battery system and they got
the controls and everything, wires running straight
through the bar stem, adjustable, heated grips
so you can ride in winter. You don’t have to have
big, cumbersome gloves. You can have much thinner
gloves, better riding feel, and, of course, no numb hands. How cool is that? Something else really cool
I’ve seen here at Topeak is this Airbooster G. So this is something that’s
for using with C02 cartridges, and, of course, as we
know, one of the problems with C02 cartridges, you don’t
actually know how much air you’re releasing at any
time, even with those that have got a valve on them. These have got a pressure
gauge on them, so you can be really precise in the amount
of air you’re releasing into your tires. My perfect example of
really cool, new MTB tech, just stuff that works really well. You might not always need
it, but they make a tool for everything you could possibly need. Gotta love Topeak for that. Here on the Gates stand, check
out this Nicolai ION-G15. Now as well as being a really modern bike, of course it’s very progressive
geometry, long, low slack. This, of course, has got
the Gates Carbon Belt Drive on that, in combination
with the Pinion gearbox. This, I really think, could
be the future of design as far as bike transmissions go. Think what you’re doing with this. You’ve got something that’s
completely impervious to mud. You’re never gonna have to maintain this. It’s all sealed away inside there. You’ve got the actual
Belt Drive system itself. There’s no chain to snap. Really quiet, efficient system on there. You’re making your unsprung
mass a lot lighter, so the rear suspension’s
gonna work better. The weight of all of that
stuff goes on the mass of the bike, so the whole
bike’s gonna feel more balanced. The shifting system with
this feels incredible. It’s really good, and, of course,
it is all work in progress towards what the future
of shifting will be on mountain bikes. And I, for one, really hope
it does go the gearbox way, because I love the way it
does without all of that stuff on the back of the bike. Don’t get me wrong. I love what SRAM are doing with 12-speed. I love what Shimano are
doing with that stuff. It’s really good, but this,
I think, is stepping up. It’s going in a new direction,
probably the direction mountain bikes should be going in. What do you guys think? Do you think that gearbox
technology is really cool and where it should be
going, or would you prefer the humble rear derailleur? Let us know in those comments below. So I was just checking out the inside of the Pinion gearbox here, and, as you can see, this thing is loaded. So you got your input, and
you’ve got your output system on here, with flywheel
system on the outside here, as you can see where the gears change, and you’ve got these
orbitals that rotate around. Now something that’s
especially cool about this, obviously, it’s enclosed, so the whole lot is clean and safe. It basically never needs any maintenance. Every 10,000 kilometers, you
need to change the oil in it, and that is it. These are all stainless steel. These will not wear out,
because there’s nothing to wear them out. They perfectly engage every time. You can see how it works. Excellent system. Now if you consider on
your actual mountain bike how many chain cassettes you
would wear out in 10,000 km, think about oil, degreaser,
all of that stuff that you’re using, no matter
how biodegradable it is, you’re using a lot of stuff
that potentially could be dripping on that forest floor. But something like this is
fully sealed, magnesium casing. It’s in the right place on the bike. I really think this could be the future, and I’m quite surprised
there’s not more of this. But Pinion are so far ahead they’ve been developing this since 2006. We’ve seen this before. I’ve not actually seen inside it myself. Very cool to see. What do you guys reckon? So there’s been a lot of
talk about carbon fiber bikes being super expensive and
not necessarily for the wallet-conscious riders out there, but Hyper are gonna end
that in one fell swoop. Have a guess how much this costs. 500 US dollars, the complete
bike with a carbon frame. So there you go, if you
want a cheap carbon bike, this is where you come. Could this be the future? Could we start seeing a
lot more budget bikes? Let us know what you reckon
in the comments below. Of course, this is an extremely
budget by the componentry on it, but it’s a decent frame. So you could upgrade this, do
your own top mods on there, and turn it into really quite a good bike. 500 bucks! Insane. Just at the Alpinestars stand checking out their brand new Vector helmets. This is their all-mountain,
trail riding helmet, great for enduro, bunch
of really cool features on the inside and on the outside. Fully integrated peak, it
morphs straight into the helmet, but it can be pushed straight
up out the way for access, for putting the goggles on
there for those extended climbs. Enormous vents on the front
here, and, in fact, the whole sculpted style, it really
reminds me of a lot of supercars, the way it’s styled,
really good-looking helmet. Comes down to protect
the temples at the front, and the strap system actually
sits flush against the head, so it’s designed to be really
good to use with glasses so the glasses would sit on
the outside of the straps. Of course, with some helmet
designs, the straps actually get in the way of when you’re
wearing riding glasses, so it’s a really good system. And the rear cradle system
inside is adjustable, front and back, to suit if
you’ve got a more round head or, if you’re like mine, bit
more of an ovalized head. Really nice looking lid,
available in a whole range of different colors, but
that’s the racing colorway. That looks so good, I think. And this is the brand new OMNI
air-resistant spin helmet, and, of course, the spin
technology (mumbles) for sheer protection inside. It’s the same as we’ve seen
on Tectal Race SPIN helmet. Of course, this is a bit more
based along the road helmet. It’s now featuring a peak, and it’s got this really
cool bridge design. It does look like it’s
kind of wedged in between each of these things, but it’s
actually structure is part of the helmet on the inside. So very strong, very well-ventilated
helmet, and it’s very compact on the head, really
good for entry-level riders, people that may be riding
gravel, even road or commuting, or maybe a hardtail mountain bike. It’s a bit more of a basic-level helmet offering maximum protection
that looks great, really, really cool. Really impressed that
they’ve done that one. So this is a brand new
Ergon SM Comp Saddle with a pressure relief channel in there. Their saddles are already
extremely comfortable, but now they’ve got the new
Orthocell foam on there, which is insanely
comfortable, really malleable. The channel is wide all the
way to the front, so you can perch yourself forwards
for those steep climbs without putting too much
pressure on your perineum area. Really nicely thought-out
saddle, nice and light, various different options here. Big fan of the stealth
colorway on that one. Now they’re also compatible
with the Topeak QuickClick Mount which locates on the bottom
here, and you can mount various different tools
and saddle packs and stuff on the underside of the
saddle there without having to rely on the saddle rails for that. Really neat system. Now KTM have got a serious presence here. It’s probably the biggest
stand we’ve ever seen. So we’re just gonna have a little look at some of the cool bikes they’ve got. Now KTM have obviously got
bikes in every single category here, ranging from e-bikes,
commuter bikes, road bikes, hardtails, and something like this. This is a 29-inch prowler. 150 mm travel, full carbon, this thing is absolutely
knock-out gorgeous. Love that line all the
way down to the back of the bike there, classic
Horst-link at the back with a shock being driven by a swing link on the top tube there. That is a really, really
nice enduro trail bike. Unlike many of the bikes
we’ve seen here, it’s running the brand new X2R 12-speed,
which I think is stunning, absolutely really, really nice looking. What do you guys reckon? Would you run the Shimano X2R 12-speed, or would you prefer a SRAM Eagle? Hm, there’s a question for you. Let us know in those comments below. So I’ve just had a walk
around the KTM stand. I’ve counted 52 e-bikes. 52 e-bikes. And, of course, there’s
these hardtails here. There’s 13 hardtails
here, but the best one, I’ve already found this one. Neil is gonna love this bike. This is a proper high-end, XC race bike. So this is the Myroon. This is the absolute weapon. It’s running the Step-Cast
fork on there from Fox. That’s the super light XC fork. 29-inch race wheels on
there, Thunderbird tires, super fast-rolling, full
carbon frame on that, really tight back end,
super clean line that runs all the way down to the chainstay there. That’s got Neil’s name
written all over it, I reckon. Now something else that
Magura do a little differently to everyone else is apply
different style brake levers for a different feel, and we all know how important brake feel is. And a lot of riders
actually pick the brakes, regardless of power, on
how the lever feel is and the position of them on the bars. You’ve got the Danny MacAskill lever here. You’ve got carbon levers,
which are great for XC riders. And, of course, as we
talked about on the show a few weeks back, Loic
Bruni has got his own lever in development. This is one of his actual levers. It’s a 3D-printed,
titanium rapid prototype. It’s just amazing. I think it’s a really cool concept. You can have the brake. You know what the power’s gonna be like. You know how to bleed them,
and you pick the lever to get it how you want the brake to be. Absolutely love what Magura are doing. So there we go. That is another cool bunch of tech stuff. Let us know in the comments

100 comments on “The Future Of Mountain Bike Tech At Eurobike 2018

  1. I bet a good percentage of people attending Eurobike are those pesky "bike vloggers" who make everyone their enemy

  2. Why on earth would people go from cassettes and cranks, which are basically stepped CVT with variable drive gearing, to a primitive 19th century layshaft design? That's basically what that 'pinion' gearbox is, just a manual transmission from a car adapted to input from a crankset instead of a crankshaft.

    Sorry, but that is not impressive. They are simply using an ancient design for the wrong kind of vehicle (1 human powered bicycle)

    Also, those are dog cut gears, no way they have 'perfect engagement' you need helical cut gears to even approach that. I can HEAR the noise when they mesh from the video itself, forget the losses from actual driving (or pedaling in this case). Furthermore, layshaft gearboxes need the input and output shafts to have matching angular velocity to have perfect shifting and quite frankly, thats impossible unless you have a clutch and neutral gear to let you do that.

  3. XTR 12×2 for my XC bike with the 10-45 cassette. Almost the same gear spacing as my outgoing XT 11-36 10s cassette but with the wider range. But I can still keep the jumps narrow and weight down all while have better climbing and descending gears vs a 1x where you have to sacrifice one or other. Definitely looking forward to getting my hands on the new XTR 12×2.
    I think a pinion gearbox is great for Enduro and DH riding where maybe weight isn't a major concern frames can be designed to accommodate it without to much weight penalty and gets the derailleurs out of the equation in terms of object strikes. But for XC racing I think the humble chain/derailleur is still best due to its light weight and being an established technology it doesn't need any redesigning in terms of frame design so frames and drive trains can remain nice and light.

  4. carbon fiber on a mountain bike…, now thats just plain brilliant planned obsolescence. stack once and your frame is a shattered mass of fiber and resin with a point as sharp as glass. what happens if you impale yourself on that spear point in the backwoods… Oooops…..

  5. changing oil doesn't count as maintenance ?! stainless steel gears won't wear out because they very well what a pile of lies

  6. Thanks, Doddy, I like the shoes and the gearbox and the high-dollar KTMs and the low-budget Hyper mountain bike, although I prefer alloy frames for their durability in daily grind of all-season commuting on a mountain bike with road tires. And I don't like the integrated bars with the light and tech housing and what not. But the bars with the damping core sound good. And I still like GripShift, too, just twist and ride it like a motorcycle.

  7. Nice new tech, I like the heated handlebars with the centered light. How much weight does the pinion enclosed gear box add to a bike compared to a traditional gear set up? The affordable carbon 500 dollar mountain bike may be a something which will attract new buyers.

  8. hey GMBN TECH have u ever heard the VYRO Component thats 2 speed chainring can change itself without front deraileur can you review it how its work? because i really confuse when first i see it on intagram..thank you

  9. 8:00 yeah never liked derailleur. it's hard to pronounce, breaks all the time from snapped chains and bumping into things, annoying to tune. almost everyone has had the unfortunate incident of having to remove the damn thing and snap the chains just to get home.

  10. yeah those $500 carbon frame bikes are gonna destory the long running carbon fiber monopoly who've kept the prices way up for their 3000% profit margins.

  11. daaang ktm stepping up the mtb industry. It will be good to see how they grow in the mtb world and see how bigger following they can get

  12. His ugly face is much more interesting than the Nicolai ION we never get to see. This is crap Doddy, your crap Doddy, go back to bed Doddy.

  13. I'd like to kindly #askgmbntech to give a review of Northwave Clan shoes as soon as they will become widely available.
    I'm really curious about how they perform (grip, breathability) compared to Five Ten Freeriders!

  14. Nice review Doddy, I do have a question however it’s not bike related! I like the look of the small camera you were carrying around the exhibition. Can you let me know the make & model of it please?

  15. My understanding of the hyper x isn't that light. To lighten you would have to upgrade to better components greatly increasing price

  16. boooo on e-bikes! that pinion gearbox makes the new 12 speed cassette/derailleur stuff look 20th century. can't wait to get a gearbox bike.

  17. 4:55 I prefer share the key. Especially when you simply can lost your device – the only key. In any case, all those locking devices never provide any feasible solution (I mean, will it be able to resist long enough? In my case it would be 12 hours).
    6:00 … question: how can I customize it? Or it is blackbox: broken throw away, buy new?
    8:36 Isn't it too massive? Steel gears?
    12:08 Wright rating? I'm rather heavy person, and these miniature saddles usually live short period of time here.

  18. 7:20 I have drawing of a bike just like this that I drew up as a kid, no joke I can show you the drawings I still have them!!! I used to read all the magazines and draw bicycles while I should have been learning in school nearly 15 years ago!!! I was tired of wasting derailleurs!!! Its about time!

  19. 9:48. It took that long for this gearbox to come to market? That seems strange to me because car and motorcycle transmissions have been around for a long time

  20. Did you know, first there were cycles, then people started adding engines and we got motorcycles. Now we have cycles, people are adding engines and gearboxes to them so they are called e-bikes? But we arleady have electric motorcycles. I'm confused, what is going on?

  21. I'm thinking about getting the Trek Fuel EX 5 29 – 2019. My local bike shop has it for 1899.99. Any opinions?

  22. I think the gears were actually CGI'ed in the shot that's why you never got good static shot or demo and more duphis presentation . Oh yeah I also saw two shadows of the bike on the ground. !!!!! Planet with two Suns, I think not.

  23. Cameraman showed completely unremarkable carbon walmart bike, but not a very interesting gearbox and belt drive… Thanks.

  24. Look! I love bikes but, I truly don't understand how these bikes cost more than Motorcycles. They arent using better parts than motorcycles. Motorcycles are hand built as well..

  25. Why don't they combine Pinion P1.18 (18 speed) gearbox with Rohloff (14 speed) hub? Then you could have 252 gears with 3000% gear range…

  26. UTILITARIANISM GMBN CAN YOU GUYS AT GMBN REVIEW THESE 2 FAT CARGO BICYCLES 1. THE SURLY BIG FAT DUMMY & 2. THE SALSA BLACKBORROW GX EAGLE.
    THANKS FOR ALL THE BICYCLE REPAIR VIDEOS GMBN CHEERS SHANEO 👍👍

  27. I have been riding a Rohloff drivetrain for over a decade now and I’m amazed that there aren’t more riders on them. Break the derailleur habit. They are the future indeed.

  28. There's a good reason motorcycles don't use fully faired in cables, etc. You may like it right up until you have to do any maintenance, ask a scooter tech how much fun it is to work with. Biggest issue with fully enclosed spur gears, they are going to be HEAVY, particularly if all stainless steel, magnesium case isn't going to cut enough weight to compensate for the mass. If the gears get lighter, they may not be reliable and there is no way to fix it 'out in the woods'

  29. no kidding…7:30 to get to the transmission,which is HUGE,by the way(is that for a harley?)…it still has a chain to the rear so…why not an enclosed shaft too?and why does the bike look stolen and abused?and…is this guy a vegetarian???woof!

  30. Pinion gearbox system is really heavy. Even heavier than than the rolloff hubs. It is only used on touring bikes at them moment where weight isn't such a big issue. I like the concept but it needs to lose weight.

  31. Definitely see the vintage derailleur going away, we need a small light gearbox. Idk why it hasn't been here yet.

  32. Two problems with the pinion gearbox. 1/ not able to shift under load. 2/ grip shift.

    Surely grip shift could be fixed with a trigger system on each side. the only thing i can think of for shifting under load is some sort of clutch system.. but not sure. Electronic shifting?

  33. I love them magura brake levers for the price of hydraulic brakes. Not. Great that the press is showing disapprobation for this kind of behaviour from manufacturers….oh wait, they praise it.

  34. https://youtu.be/2N86N0P5MxM

    What is this guy talking about the derailer being mounted to a bracket vs a frame?

  35. I understand leaving you wife is fine but why would you leave a bike like that locked to the wall. It is screAming to be ridden. Unlike your wife.

  36. I developed an oscillating pedal that is very efficient and it is the World's BEST design. Use a conventional bike, just remove it's cranks, spindle and chainwheel then assemble this invented mechanism . The conventional bike frame's bottom bracket will be the housing of this invention….. https://www.youtube.com/watch?v=n1ZPAnzWEwo

  37. This is bittersweet thought-provoking the Bittersweet aspect is how many bikes have have stolen that were super bikes only two but they were prototypes they always got better the others I sold for parts or I fixed up the entire bike and traded It for parts and then when I got enough for the parts I needed I would build a Superbike it took years sometimes but the ones I had were well worth the trade😔 the good news is I never lost a race never 😎

  38. 500 for that hyper? Carbon or not, that's way too much for that spec. U can get a sweet hardtail on closeout for 500, or even a bikes direct bike would be far better

  39. Anyone else think bike names are getting worse? The KTM Prowler! Where on a steady decline here. What's next the Trek Stalker, The YT Fritzel, The Intense Manson, The Whyte Shipman and worst to come The Specialized Copyright Lawyer

  40. they still make 29ers other than for beginners who haven't learned how to ride and feel a trail, that is what its about!

  41. i don't think a gearbox with a belt will ever be the way to go, it just eats too much power and no amount of maintainance freek biking will make up for efficency loss.

    i however think that gearboxes could be a great thing on E-bikes. the electric motor helps with the pedaling and the loss of efficiency is not a problem on those bikes.

    but i'm shure that the different manufacturers of gearboxes for mountainbikes will prove me wrong at some point or that i am wrong already.

  42. 11:57 MAYBE A HARDTAIL MOUNTAINBIKE!?

    IM DEEPLY OFFENDED BY YOUR VISION OF HARDTAIL MOUNTAINBIKES NOT BEING ABLE TO ROCK.
