- This is former professional ski jumper,
and time trialing star,
Primož Roglič's Bianchi Oltre XR4.
Underneath the saddle, they've written on the weight.
It weighs in at 108 grams.
Only 108 grams.
It's a Selle San Marco, Superleggera saddle.
It's got carbon fiber rails and a carbon fiber body.
And if you look at the saddle,
one thing you can't help but notice,
is that the Dura Ace Di2 junction box
is actually zip tied to one of the saddle rails.
So, the Dura Ace wires come up, out of the seat post
and here it is, zip tied right there.
I've literally never seen that before
on a pro bike until now.
The seat post on the bike is Bianchi,
so that's part of the frame set.
He's got an FSA OS99 stem,
and FSA Extra Light handlebars,
and they are the new Ergo, ergonomic shape.
Bar tape is also FSA,
and that is the Bianchi signature Celeste color.
Also in the Bianchi signature Celeste color
are the bar end caps.
It's a very cool little finishing touch.
Breaking and shifting on this bike is provided by Shimano.
It is the latest, the new version
of Shimano's Dura Ace Di2.
He's got a couple of satellite sprint shifters there too.
They are very, very close to the brake levers,
just nestled in on the drops.
The shifters are connected up to Shimano Dura Ace Di2
front mech and a Shimano Dura Ace Di2 rear mech.
And the brakes are Shimano Dura Ace,
they're direct mount, front and rear.
The chain set on this bike is also the new Shimano Dura Ace,
and that has a Pioneer power meter.
The Pioneer power meter is dual sided,
so it gives Roglič feedback on measurements
such as left leg power versus right leg power.
A lot of interesting data like that.
Pedals, they're Dura Ace also,
the chain rings are Dura Ace, they're 53-39,
the chain is Dura Ace,
and the cassette, that's Dura Ace, too,
and that is an 11 through to 28.
In keeping with keeping this bike as light as possible,
Roglic's has gone for Shimano Dura Ace C40 wheels,
so they strike the perfect balance, arguably,
between lightweight and aerodynamics.
The tires that are glued to those wheels,
they're tubular tires, are Vittoria Corsas,
and they come in at 25 millimeters
according to the stamp on the sidewall.
Bottle cages on the bike are provided by Tacx,
and because this bike is meant to be as light as possible,
there are a load of, to me, and hopefully to you,
absolutely fascinating little details.
I've already mentioned the Dura Ace junction box up there,
I've already mentioned the fact that
the weight of the saddle,
because weight is such a priority on this machine,
is actually written on the underside of it.
The bottle cages are lighter than
the ones that the team would normally use,
the handlebars are extra light,
and then, well there are a couple of things that add weight,
too, so just on the chainstay here,
that looks like helicopter tape,
which is designed to prevent the chainstay from chipping
if there's any chain slap or anything like that.
And because the bike is Dura Ace Di2 and not mechanical,
there are actually a few surplus cable entry and exit points
which the mechanics have taped up
using black insulating tape just to stop
any water or dirt getting in there.
With all that covered, it's time for some vital statistics,
and I need to run over to my bag
and get everything for that.

Starting the measurements from the very bottom of the bike,
Roglic's cranks are 170 millimeters long,
and the saddle height comes in at around 71 centimeters.
The reach from the nose of his saddle
to the center of the stem comes in at 54 centimeters,
and his bars are 42 centimeters wide,
and the stem is a 12 centimeter stem.
The tires, although they're marked off as 25s,
come in, according to our calipers,
at about 24 millimeters wide.
The weight of the bike,
as we promised, it is super light
because there's been so much effort and thought given
to just how to save weight on the bike,
I actually imagine they probably weighed this one down
to make sure it meets the UCI's 6.8 kilogram weight limit,
the weight is 7.1 kilograms.
That's a little bit louder than I'm used to
for a Dura Ace C40.
I like loud free hubs.
I've really enjoyed looking at Primoz Roglic's
ultralight Bianchi Oltre XR4 bike that he's gonna use
in the mountains at this year's Tour de France.
I hope you have too, I'd love to hear your thoughts,
down in the comments.
