Alberto Contador's Trek Emonda SLR | Tour de France 2017 - Duration: 5:44.

(heavy music)

- This is Alberto Contador's brand new Trek Emonda.

Now the previous Trek Emonda was just 690 grams

for the frame, and this one, just released,

is now 640 grams, and that's for the same size frame

as Alberto is riding here, which is a size 56.

Now, Trek's sell two different geometries to

their Emondas.

H1, which is the super low, racy one, and H2,

which is ever so slightly more upright.

Predictably, perhaps for a seven time Grand Tour winner,

Alberto Contador chooses the super racy H1.

As well as stripping weight out the frame, Trek

have also managed to beef it up at the same time.

So the front end and the bottom bracket have both

been made quite significantly stiffer.

Shimano's latest 9100 series Dura-Ace groups

has been quite slow to make its way into the pro ranks,

but Trek and obviously now, Alberto Contador

have managed to get their hands on some.

But, he's still not running the complete groups yet.

So he's on Dura-Ace DI2, so the electronic version.

He's got 9150 shifters, and he's also got front

and rear derailer.

The rear derailer in particular is quite a bonus because

it's got extra capacity, so he can now run

an 11 to 30 tooth cassette.

And we're told that potentially, even for some stages,

he might change the inner chainring for a 38.

So that's a pretty low bottom gear.

Currently he's got 53-39 on there and and 11 to 28.

You'll notice that the cranks are the older version

of Shimano Dura-Ace, and that's because you'll see,

just in there is SRM PowerMeter there.

And then he's got an SRM PowerControl, version eight

up front.

And one final component on this group set

that hasn't been changed to the latest Dura-Ace is

the brake callipers.

And that's not because they're not available; they are.

It's just that Alberto and his mechanic decided

that actually he wanted to stay with the older ones.

That's because of the brake's quick release.

So on the new one, it's very binary, it's on or off.

Whereas the old one, you can still toggle the position.

And apparently Alberto wanted to keep riding that

for potential emergencies, and so he hasn't made

the transition to the new brakes.

The wheels are Bontrager Aeolus 3s, and those are

the super lite climbing wheels.

And when I say super lite, I mean super lite,

just 1150 grammes for the tubular versions which, of course,

being a pro-racer, Alberto is using.

He does have plenty of options at his fingertips.

He'll often ride the Aeolus 5 and even the new Aeolus 6

on flatter stages.

These are quite wide wheels and so aerodynamically

the best tyres to use on them are 25 millimetres wide.

And so that is what is on here.

We've got Victoria Corsas in that exact width.

The finishing kit all comes from Bontrager,

so we've got a Triple X one piece bar and stem up here.

Apparently Contador is the only rider on the team

to choose this one, and it is a really stiff setup.

And so, apparently, he likes the consistency and feel

from this to the one on his aerodynamic

Trek Madone bike as well.

Saddle is a Bontrager Serano RXL.

And then lastly we've got these Triple X Lite

bottle cages as well.

Now the moment of truth for Alberto Contador's pro bike.

Given how light the new frame is, what is the overall

bike weight gonna be.

Whoa!

That is light.

That's 6.5 kilos.

Now I think Trek's mechanics are gonna be adding

some serious ballasts to this frame.

Apparently there's already plenty in there;

maybe even up to 400 grammes.

The reason it's not bang on the UCI weight limits

of 6.8 kilos at the moment, is because the

Vallon Transmitting devices that are added to the bikes

can be included in the UCI weight limit.

So firstly, they need to put that on, and then

they can sort it out.

But nevertheless, 6.5 kilos!

With pedals, bottle cage, head unit.

That's pretty light.

Pro bikes are always immaculately maintained

and utterly pristine.

But it has to be said there is something about

an Alberto Contador pro bike.

It's always utterly, utterly perfect.

And the credit goes to his longtime mechanic, Faustino,

who is clearly an absolute artiste,

and very, very proud of his work.

Everything; let's just look closely at the bar tape.

So Alberto always runs double wrapped bar tape.

And that there, that in itself is a work of art.

It's utterly, utterly beautiful.

And then the fact that the cables are lovingly

shrink wrapped together, the DI2 Electronic wires,

and the rear brake cable there.

I cannot imagine a better maintained bike

exists anywhere in the world.

In fact, if you can imagine a better maintained bike,

then let us know in the comment section down below.

Let that be a challenge.

Can anyone beat Alberto Contador's mechanic, Faustino?

Right, if you like pro bikes, and who doesn't?

And there is one every single week.

If you're after some more content right now, though,

firstly you get a little bit more information on this

brand new Emonda frameset.
