Pinarello couldn’t have hoped for a bigger debut for their new Graal time trial frameset, with Bradley Wiggins (Team Sky) winning the Giro d’Italia prologue in its competitive debutJames Huang
A new set of Pinarello MOst integrated aero bars is fitted to the front of Wiggins’ GraalJames Huang
Three holes in the bottom of the Pinarello MOst integrated aero bar makes for flexible cable routingJames Huang
Wiggins is able to maintain a very narrow position on the barsJames Huang
The stem and base bar are one integrated piece but it looks like the upper assembly can be swapped for different sizesJames Huang
Small pieces of tape cover up the bolt holes on Wiggins’ aero bar setupJames Huang
Wiggins’ machine is fitted with a ceramic bottom bracket from UK-based Ultimate Ceramic BearingsJames Huang
The front brake is tucked in behind the bulbous fork crownJames Huang
The chainstays start out very narrow and tall but end up fat and flat at the dropoutsJames Huang
Team mechanics installed a set of standard Dura-Ace chainrings prior to our photoshoot, but Wiggins used his usual O.symetric rings for the prologue winJames Huang
Wiggins’ usual Dura-Ace front derailleur is mounted to the aluminium tab – and the extra spacer sandwiched in between is further evidence that O.symetric rings are usually in placeJames Huang
Wiggins’ Dura-Ace rear derailleur is hopped up with full ceramic bearing pulleys from UK-based Ultimate Ceramic BearingsJames Huang
The blue swatches on the down tube are meant to highlight the surface shaping – which is presumably there to reduce aerodynamic dragJames Huang
The down tube is fairly narrow but not overly so to retain good front triangle stiffnessJames Huang
The scissor-type front brake is well hidden behind the fork crownJames Huang
The top tube is rather tall and broad, allowing the down tube to be narrower without sacrificing front triangle stiffnessJames Huang
The head tube retains Pinarello’s trademark shapingJames Huang
Wiggins clearly places a very high importance on reducing friction with both the bottom bracket and derailleur pulleys rotating on ceramic bearings and the front hub running without any sealsJames Huang
Wiggins puts the power down through a pair of Shimano Dura-Ace SPD-SL pedalsJames Huang
The curvy seatstays are deep but narrowJames Huang
Prologo’s Nago Evo TTR time-trial-specific saddle is wrapped in Team Sky coloursJames Huang
The seat binder is neatly integrated into the frameJames Huang
