The Graal’s used by Team Sky may be the same as Movistars in terms of their frames, but as ever, the devil is in the details. One obvious difference is the front end.
Rather than use a Pinarello bar and stem, or anything from sponsors Pro, Sky has pieces from the same independent supplier used on the track bikes by the Olympic team. Carbon stem and bars are one piece, and the height of the extensions is adjusted via aerofoil profile risers hewn from aluminium. One difference between Wiggins and teammates is the mechanical shifting.
In order to get his position optimal – read far enough forward – Sky use the difference in the UCI’s rule book between where measurements are taken for rotating and static (electronic) shifters to gain an extra 40 odd mm of reach. He may loose the ability to shift from the bullhorns, but other marginal gains outweigh this loss.
Despite his use of mechanical shifting for positional reasons, the integrated brake levers feature unconnected shift buttons for the Shimano Di2 used by other riders.
Like Cancelara, Wiggins utilized oversize jockey wheels to reduce drive chain friction.
Although they have caused a few inopportune mechanicals, Wiggo sticks by the Osymetric chainrings.
Close inspection of The Hed tri-spoke on the bike reveals exposed bearings. Race day only, these need stripping down after any wet ride.
