- Myself and Jon are here
at Eurobike in Germany.
The world's biggest bike
exhibition and trade show,
on the hunt for hot, new tech.
- Ollie, what are you wearing?
(record scratching)
- This is what everyone
wears in Germany, Jon.
- No, they don't!
- Lederhosen, socks, sandals,
you're part of my cunning plan, right?
By blending in with the locals,
I'm going to be able to get
close to the hot, new tech
without them suspecting (chuckles).
- All right, well, I'll
tell you what then,
you walk in that way, the
opposite direction to me, please,
and I'm going to go over there
and I just hope you
brought some other clothes.
- Right, let's do it!
(playful string music)
- Last year at Eurobike,
we showed you the
CeramicSpeed Driven system.
12 months on, here is Driven V2.
Now, this one has a fully
functioning gear-changing setup.
How exciting is that?
And, apparently, it's even
got a torque decoupler
built into it, too,
which is a first for me.
Now, I don't know all
the ins and outs about it
because it is so brand new.
So, I'm going to have to speak to Jason,
who's the head engineer,
to find out exactly
how this bit of tech works.
Right, Jason, explain to me,
how on earth does this work?
Because I'm looking at it
and I'm puzzled a little bit
'cause I can't see how
you can change gear,
but please put my mind at rest.
- All right, actually
Jon it's pretty simple.
We use a split-pinion technology
where the pinions will
split in an axial manner.
Whenever one half of the pinion
is away from the rear cog,
it will step over to the next gear,
so it actually moves one gear amount.
Then, as that pinion rolls through,
the other half comes away from the cog
and it moves over also
into the new shift track.
So, now both pinions
are in the same plane,
but one gear over.
- Right, okay, that's
really put my mind at rest.
Because at first, I was thinking
there's going to have
to be some sort of angle
across the teeth, if you like,
for it to sort of, ya know, blend in
when it moves along the shaft.
- So, we call it a step follower system.
And, in addition to that,
you can see that there's areas
where we have perfectly
aligned shift channels
where shifting is not a problem at all,
but we have these areas where
it's called the danger zone
where you have pure
misalignment of the teeth.
- Now, I don't like the sound of that.
The danger zone.
I try and avoid that at all times.
- So, what happens, whenever
it shifts into danger zone is,
so these pinions will move over,
but you have pure misalignment.
So, we have what's called
a torque decoupler in here.
So, as it moves over, we have
two spring loaded bearings
which synchronize the misaligned teeth
with the lead bearing of
the master coming through.
So, it synchronizes and they mesh
and as the pinion
continues to roll through
the torque decoupler springs back
and it slides over and
it completes the shift.
- There we are.
Quite complicated, but
hopefully the visuals on screen
are explaining everything,
because when you told me,
first of all, I was thinking,
there is no way I'm going
to be able to explain this,
ya know?
You're an engineer, I'm certainly not.
But, it's a great bit of technology.
- I'm at the Wahoo stand
and I found one of the
most exciting products here
at this year's Eurobike.
This is the Wahoo KICKR Bike.
Now, it's a complete indoor
exercise bike, smart bike,
that combines, essentially,
some of Wahoo's existing products.
So, the Wahoo KICKR Indoor Turbo Trainer
with the Wahoo KICKR CLIMB,
which is their device that you can attach
to the front of your bike
that raises it and lowers it
to simulate climbing when
you're riding a virtual app.
Except this one has a bigger range now
so it can be minus 15 percent gradients
and plus 20 percent gradients as well,
if you ever want to ride
20 percent gradients.
Anyhow, there's loads of other
cool features on it as well.
It's not just those two products combined.
So, these shifters are seriously neat.
So, they're covered in buttons
and they're fully customizable.
So, there's buttons on the
side, buttons on the inside,
and buttons on the top,
meaning that you can completely customize
what the buttons do using Wahoo's app,
meaning that you can set them
up like Shimano shifters,
or you can set them up
like Cam Pack shifters
with these buttons on the inside,
or like SRAM shifters with a
single button on either side.
Also, the brakes, they're
designed to work, too.
Now, at the moment, not
many indoor training apps
have braking functionality,
but it's something
that we're going to see
increasingly more of in the future.
So, the bike is
future-proofed in that regard.
In terms of adjusting it
to your exact size and specifications,
Wahoo has cleverly integrated
a Smartphone app to do this.
So, what you can do is if you've
had a Bike Fit in the past,
which is a Retül Bike Fit, you
can input that into the app
and then it will tell you
exactly how to set it up with regards
to the little graduations
and numbers that are all over
the different, movable
parts, which is pretty neat.
Or, there's another cool thing,
where you can take a picture of your bike
using a sort of augmented reality photo
and it will tell you
based on what your bike is
how you should then transfer
that onto the indoor bike,
which is also pretty neat.
The crank lengths are changeable as well
by way of these different holes.
So, you've got a choice
of 167 through to 175.
I quite like that because,
well normally I ride 172.5's.
I've never tried shorter cranks,
but I'd be tempted to do
so and using this I could.
It would be the perfect
tool for the job to do that.
So, on to the business end of the unit,
and in here you've got the power meter
which is accurate to
plus or minus one percent
and has a max power or 2,200 watts,
which to be honest,
probably not going to
be enough for these guns
but it'll probably be
adequate for most people.
And they've actually updated it
from what's found on the KICKR.
So, you've still got the big fly wheel
which gives a really
realistic indoor road feel,
but they've added a little
motor to it as well,
and this means that when
you're on, say, a long descent
in a virtual world, such as
Alpe du Zwift, for example,
a fly wheel will eventually
spin out and stop spinning.
But, with the motor added
to it, it can keep spinning
and keep that momentum,
and keep a more realistic,
free-wheeling experience.
Also, and I really love this,
the motor has been tuned so
that it kicks in slightly
and gives a little kick
every time you change gear
on the shifters, which gives
that really realistic slight
kind of, well, when you
change gear on a road bike
you can feel it at the back
and that's what it's designed
to do, which is really neat.
And, while we're on the subject of that
I mentioned that you can tune the shifters
in the app to whichever
type of shifter you like
be in Cam Pack, SRAM, Shimano, whatever.
But, you can also tune the Drivetrain.
So, if you want to run a 1x Drivetrain
you can tune it so that it's a 1x,
you can tune it so that
it's a double or a triple,
but also the sizes of the gears.
So, you could say run a
62 chain ring at the front
and have it set as an 1123 or a 12-speed
or a 13-speed block at
the back or a 10-speed,
whatever you want you can
completely customize it
in the app to the Drivetrain
that you want to try out
or is what's on your bike.
But, the added advantage of this
is you can completely set it up
to how you have your best day racing bike
but you're not wearing out
your best day racing bike
on the indoor trainer.
And this actually has a
Gates Carbon Drive in there
which is, well, largely maintenance free
and being indoors should
last indefinitely.
There's also a little display screen here
which either tells you
which gradient you're at
or it tells you which gear you're in.
It's really helpful and easy to see.
But, when you change gear,
that little vibration at the back,
it feels like changing
gear on an actual bike.
It's really weird, but it's really cool.
You just have to experience it.
But, let us know what you
think about the new Wahoo bike
in the comments below.
I wonder what Jon's up to right now?
- Right, if you're anything like me
and you absolutely love a tool,
well, the good news is
the folks at Park Tool
have just released an
almost screwdriver-like type
Allen keys, or hex wrenches
as you may well call them
in certain parts of the world.
Now, they come in two,
two-and-a-half, and three
millimeter increments
which is great for those
tiny little grub screws
you can find on bikes.
And you don't really want
to use the ball-ended part
of an Allen key, let's face it.
Because, generally you don't have
quite as good connection on there.
I'm really, really relieved about that.
In a while, I'm going to show
you some new tools down there
including one which is going
to make my life in the workshop
much easier.
Right now, at first glance,
I actually thought this
was a one-piece cassette removal tool,
but in actual fact, it's really good
because there's a little
grub screw or set screw
inside of there that you can simply remove
and change the cassette
tools that you require.
Why do I think this is good?
Well, it's more elegant, let's face it,
than using the end of a chain
whip or something like that.
Speaking about chain whips, as well,
they've also brought updated
and brought them into the modern era
of 12-speed group sets, as well.
Not to mention the fact,
they've got a new chain
splitter as well, 12-speed,
and also a new chain
checker primarily, really,
to match in with SRAM's access group set.
- 3D printing isn't new,
it's been around a while,
but many cycling brands
haven't yet found ways
to take advantage of the
new manufactuing method.
Fizik is one that has.
Check these out.
This is a new saddle from Fizik.
It's called Adaptive.
And what they've done is 3D-printed
this rather incredible structure
which replaces the foam and covering
that you would get on
a traditional saddle.
And, their thinking is that
they can actually change
this really complicated
matrix 3D structure
to adjust the, well,
squidginess of the foam.
So, you can tune the
saddle to how you like.
At the moment, the Adaptive
saddle is only available
in one model, and it's
hidden away in this box,
and it's the Versus Evo model
with a carbon rail and carbon chassis.
And you can see that these pads
are then fitted on top of it
but that's how the saddle is,
it doesn't then have a
covering that goes on top,
that's the finished product.
Pretty exciting.
Slightly lighter than a
traditional 00 saddle, as well,
but I think that's really cool.
It looks very different.
I'm over on the LOOK stand
and I've got some cool stuff to show you.
So, pretty much the hottest
things in cycling tech,
are, well, titanium, ceramic
bearings, and carbon anything.
And the new Keo Blade Carbon Ceramics
with titanium axles, tick all those boxes.
These things are seriously
cool and incredibly light.
Just 95 grams a pedal which is astounding.
So, if you compare that to the
well, Keo Carbon, the
standard one if you will,
they're 20 grams per pedal heavier.
Not much, but seriously
bling, seriously cool.
And there's actually a set here
that are Romain Bardet's custom
set from the Tour de France
with polka dots on.
Well, he's graffitied them as well.
Sure we take a note of that
so I can forge some checks in his name.
Now, although these are the pedals
that we all hark after owning,
the one's that we'll probably
buy are the LOOK Keo Classics,
which are much more affordable.
Actually, my first set of pedals
were a pair of LOOK Keo Classics.
And, they've been updated now.
They've got a larger contact patch
on the composite body which
has been almost doubled
and LOOK reckons that
this gives more stability
and more confidence when you're pedaling
with that cleat interface onto the pedal.
Nice.
- Right, I got a few
new Turbo Trainers now
coming from Elite.
In fact, it's two and a half,
'cause one of them has had a
few updates and changes to it.
But, first up is the Suito, here.
Now, this is basically
straight out of the box you can use it
because it comes fitted with a cassette
and it actually takes a
really slimmed line profile
and design about it.
Meaning that if you're limited for space
you can easily just fold it up,
put it underneath a sofa,
underneath your bed, I don't know.
Just store it away
somewhere nice and easily,
and works compatible with
all of your gaming apps
as well as through axles.
Moving then, on to the
TUO, which I really like.
And I like it because it's
actually got wooden legs on it.
Check out that.
It takes a completely different look
from anything else we've
seen out there, as does this.
I mean, it's a wheel-on trainer
so it's not a direct
drive like that Suito,
but the TUO, because of this silver box
and everything it fits in
with more modern design
housing accessories, I guess.
So, it's not going to look out of place.
Now, again it's a wheel-on
style Turbo Trainer,
so it's a more traditional
style looking thing.
I have been told as well it does work
with different types of
through axles as well
so everybody's catered for.
And it measures power, as well,
up to three percent accuracy,
which is pretty good
for a wheel-on trainer
because there's a few variables, I guess,
to be thrown into the mix there.
If we move, finally then
behind me to the Direto X,
it has got increased accuracy.
It's gone from two percent
down to one point five percent,
and gradients have gone from 14 percent
up to 18 percent capability.
We've also removed a
little bit of material here
meaning that the more modern-style
shadow plus style rail,
like this and also a bit longer
with oversized pulley-wheel
systems and everything,
they're also going to be
fully compatible into the mix.
And then, something which
I've been asking for
for years and years and years,
is this on the front of the bikes.
Check out that.
That's a steering device.
Now, there's going to be a mechanical one
as well as an electronic one, too,
so that means you will eventually
be able to link that up
when the updates come into
a virtual world of cycling,
such as Zwift, and be able to
steer around your competitors.
Finally.
I'm happy about that one.
- Here at GCM, we think
tubeless tires are great.
They're becoming far
more popular on the road
and for good reason.
You get far fewer punctures
and you can get lower
rolling resistance, too.
But, a common question we get asked
is what do you do if you get a puncture
with a tubeless tire?
Well, there are a number of things
but a common thing is to actually plug it
with a plug with a special repair kit
and thankfully Topeak have come up
with some really cool gadgets
that contain these repair kits.
So, check this out.
This is the Tubi-Bullet.
And it's this really
beautiful sort of canister
made from anodized aluminum.
And inside are all the
tools that you'd need
to repair a tubeless puncture.
So, it's a really neat
design, both ends pop off.
You've got the air-stop tool there
and then you've got the
plug tool in the other end.
And then inside this bit,
you've got three plugs in there as well.
They make the Tubi-Bullet X as well.
It's a slightly smaller version.
And, also, this Tubi-Tool Mini
which can attach to this Ninja Pod.
So, the Tubi-Tool Mini is,
well, like a standard bike multitool,
but it has the added functionality
of those tubeless repair
tools in there as well.
So, you've got the plug tool
and a little blade if you need it
and the air-stop tool as well.
Really neat.
You can always rely on Topeak
to come up with some cool little
gadgets to solve a problem.
If you want to know how
to repair a tubeless tire
using a tubeless plug like this,
well, GMBN have done some useful videos.
- All right, I'll tell you what,
I'm pretty teched out
after all that (sighs).
- Been a long day.
- Yeah, it has indeed.
And while I've seen loads here,
but we've barely scratched
the surface, haven't we?
- Yeah, there's so much here.
So, make sure you subscribe to GCM Tech
if you haven't already.
Click the bell icon, that
way you won't miss any videos
because we're going to be
uploading more videos like this
over the rest of the course of the week.
There's loads.
- Yeah, That's right, and Ollie,
you've been banging on so far,
All about these tech clubs
or techno clubs, so--
- Yeah, I think, let's go.
- Okay.
- (German accent) Ollie
and Jon ist in the disco.
(speaking German)
- I wish you wouldn't do that.
Go on, then.
- Let's go.
