(upbeat music with drums and brass)
- So this is the Specialized S-Works Venge ViAS
belonging to triple world road race champion
Peter Sagan of the Bora-Hansgrohe team.
So, starting with the saddle,
it's a Specialized S-Works Romin Evo.
It's the model here with the cutaway in the middle,
and it's got carbon rails,
and the measurements from outside to outside
is 143 millimetres.
And then the breaking and shifting levers at the front
are Shimano Dura Ace 9150.
That's the latest model of Dura Ace, Di2.
We've got Supacaz bar tape,
which I must say is ever so sticky.
And he's also got himself some sprint-shifters
fitted underneath that tape.
And keeping that bottom bracket turning
is a Ceramic Speed option, naturally
coming with ceramic bearings.
Now, this is very interesting, that I've just noticed.
The right pedal is in fact a Shimano Dura Ace 9000,
and the left pedal is a Shimano Dura Ace 9100.
So, if you look on top of the pedals there,
there's actually metal parts in different places
on the respective pedals.
Presumably that's something that Sagan notices
and he requests to have non-matching pedals.
First time I've ever seen that.
Now, fitted to the spider of the chain set here
is what appears to be, on first glance,
a Specialized power metre.
However, I do believe, and this
is only my opinion, that it is in fact
a 4iiii power meter underneath there.
And the same goes for the inside of the left hand crank.
And just to make sure that the chain stays on,
there is a K-Edge branded chain catcher there
on the inside of the front chain ring.
Now, both front and rear wheels are provided by
Roval, and that's an in-house Specialized brand.
And the depth of them is 64 millimetres.
The model themselves are the CLX64 Rapides.
Mounted on them are Specialized S-Works Turbo
tubular tyres, and they measure in
at 26 millimetres on our callipers.
Now, on the centre of the rear hub,
it does actually say DT-Swiss technology inside.
However, that does appear to be slightly darkened over.
The chain is provided by Shimano,
and that's the HG901.
Now, the brake callipers are not something you're going
to find on any other bike on the market.
They are, in fact, specific to the Venge ViAS.
And as you can see, they are pretty unique-looking,
aren't they?
Now, the operation of them, they work
in the same way as a V-brake that
you might find on an old-school mountain bike.
So, they pull in from the side,
and they've also covered up with exactly
the same rubber grommets that we used to find
on those bikes.
Now, you may well be wondering where on earth
the Di2 junction box is.
And it's stored right underneath here.
Underneath the bottom bracket shelf.
It's housed inside of a plastic case
and the good news is, the adjusting button
is still easily accessible for maintenance.
Now, Sagan's wheels actually have these
special World Championship-edition stripes
printed onto them, with a nice play of words
on there, too.
Wind Tunnel Engineered.
Now, the brake pads, they are provided by
SwissStop, and they're carbon-specific,
which is of course very important
when using carbon wheels.
Sagan, he chooses to use 172.5 millimetre
length cranks.
Now, the seat post is a Specialized FACT carbon,
and obviously that's unique to this frame
because of the shaping of the tubing.
Now, Sagan has opted to use a 56 centimetre size frame
here, and that stem, that's nicely slammed down now
on top of that aerodynamic headset cover.
Now, the stem is a Zipp model.
And the logos themselves are actually covered up
with some black tape.
The length of it is a whopping 145 millimetres long.
You won't find many more longer than that in
the Pro Peloton.
Now, measurements-wise, from the
tip of the saddle to the centre of
the handlebars, that's coming up at 62.9 centimetres.
And the saddle height, 75.5.
And Sagan's bike, weight-wise, comes in
at 7.6 kilos.
(swoosh sound, playful music)
- Right, back in the GCN lab, and based on
a few of the measurements that John took,
and thanks to our maths geniuses here,
we have got some extra insight
on Peter Sagan's bike, that we're going to be
able to share with you.
First up, we're gonna talk about layback.
Now, layback is the horizontal distance between
the nose of the saddle, and the centre
of the bottom bracket.
It's a critical measure for bike fit.
John took a measurement of the nose of
Peter Sagan's saddle to centre of the bottom bracket,
which was 753 millimetres.
So based on a bit of trigonometry,
753 SIN (8), we get Peter Sagan's layback.
As you can see there, which is 105.1 millimetres.
Next up, it is saddle to bar drop,
which is less complicated than layback to explain,
but it's still a critical bike fit measurement.
John took a measurement from the nose
of Peter Sagan's saddle to the centre of his bars,
which came in at 629 millimetres.
Based on a couple of calculations then,
we get a saddle-to-bar drop for Peter Sagan
of 76.7 millimetres.
Which, probably sits in the midrange
for pro bikes, not too extreme, equally not too relaxed.
John, back to you.
- [John] And now it's the time you've been
waiting for, the free hub sound test.
(whirring, cyclical sound)
Now as some finishing touches to this bike,
we've got ourselves some Tacx carbon fibre
bottle cages, Peter Sagan's name of course
is on the top tube, there.
It's got the Slovakian flag as well as
the world champ stripes.
We've got a 3D-printed number holder, too.
Now, with 3D printing rapidly coming down in price,
it means mechanics can totally customise these parts,
and this one fits perfectly on the back
of this Specialized FACT carbon seat post.
Now I must really thank Pete Sagan for allowing me
to check out his bike, I hope you've enjoyed it.
Let me know what you think of it down there
