Tour Tech 2017 video: Geraint Thomas’s Pinarello Dogma F10 X-Light

This is the Pinarello Dogma F10 X-Light belonging to Team Sky’s Geraint Thomas who has been in the Tour de France leader’s yellow jersey since victory in the individual time trial on the opening day.

Pinarello has had three versions of the Dogma F10 approved by the UCI: the straight Dogma F10, the Dogma F10 Disk and this Dogma F10 X-Light. Of these, only the first has been officially launched by the Italian brand but you can expect to hear more about the other two before long.

The Team Sky riders were on Dogma F8s last year and then Pinarello brought out a limited edition F8 X-Light which came out of the same mould but which was lighter thanks to a new carbon-fibre layup. Pinarello suggested that it should be used only by athletes weighing below 75kg. We expect the F10 X-Light to be similar. 

Is Geraint Thomas actually on an F10 X-Light as opposed to an F10, though? The logo on the seat tube says so, but look closely and you'll see that the “X-Light” bit is on a sticker that has been added to the existing frame, so maybe it’s just a marketing thing.

It almost goes without saying that Pinarello claims the F10 to be lighter and stiffer than the F8. Pinarello gives a frame weight of 820g for a 53cm F10 and it’ll presumably be lower still for the F10 X-Light.

Pinarello also claims that the drag has been reduced by up to 20% and says the Dogma F10 saves 0.8secs per kilometre over the F8, which amounts to 2mins over 150km (although it doesn’t state at what speed this result was achieved). 

While retaining the flatback down tube profile of the F8, the F10 takes a few lessons from Pinarello’s Bolide time trial bike with tube profiles that are designed to smooth the airflow around the water bottle, which is placed lower in the frame than before. 

The Shimano Dura-Ace Di2 control junction box is now hidden inside a compartment in the down tube so it doesn’t hang below the stem, and Pinarello has switched from dual pivot to direct mount brake callipers. 

Whereas Geraint Thomas has had his frames decorated with the Welsh Dragon in the past, there’s no personalisation of this frame beyond a simple name sticker. 

The groupset is Shimano Dura-Ace throughout. The chainset is 53/39T.

The wheels are Shimano Dura-Ace too: they’re C40s with 37mm deep and 28mm wide rims, optimised for wider tyres. The tyres are Continental’s Competition Pro Ltd in a 25mm width. 

Shimano’s Pro brand provides the 131mm Vibe stem and handlebar. 

The saddle is a Fizik Arione with carbon braided rails.

That’s a K-Edge Garmin Race Mount at the front and Thomas’s bike is fitted with superlight and not crazily expensive Elite Vico Carbon bottle cages.
