Pinarello’s latest Dogma follows the philosophy of ‘if it ain’t broke…’, as the F8’s frame has stayed the same since its launch. This is no bad thing as far as we’re concerned, as the F8 featured marked improvements over its 65.1 predecessor. And as Froomedog claimed his second yellow jersey on this bike last year, it’s not like it’s slouching its way through France…
Aero-optimised frame with neat details
As with many pro machines Team Sky’s bike has an aero-optimised frame, in this case featuring main tubes with what Pinarello calls a ‘FlatBack Profile’. It’s a profile that’s usually referred to as Kamm-tail, a truncated aerofoil that has an aerodynamic advantage but that doesn’t contravene the UCI’s 3:1 aspect ratio rule [the depth of the tube can’t be more than three times the width].

But for what is essentially an aero road bike, the design is clean and fuss-free, even though it has some very neat touches. The bow-legged fork is designed to reduce turbulence from the rotating front wheel, while the fork crown is shaped to closely match the standard brake. The asymmetrical frame is typically Pinarello, and is claimed to equalise the drivetrain forces.
While the frame is essentially unchanged, the same isn’t true for the rest of the bike. MOST’s new one-piece Talon bar is designed to be as aerodynamic as the bike, complete with teardrop-shaped stem and spacers. But what truly impresses with the F8 is the comfort that the frame and fork deliver. A bike with oversized aerodynamic tubes could easily be rigid and uncompromising, but the F8’s rear end plushness, in particular, is impressive and the comfort really shines through.
Rock-solid front end
The front does feel stiffer than the last F8 we tested, which has to be down to the rock-solid-feeling one-piece wing bar, but the hooks have a great shape and the flats on the bar tops aren’t so wide that they’re uncomfortable on long climbs – something the F8 has seen plenty of.
