UHC Performance carbon fibre The B12 combines one of our most aerodynamic frames made from Felt UHC Performance carbon fibre with race-worthy components for a sacrifice-free performance. Shimano Dura-Ace derailleurs are paired with microSHIFT 11-speed shifters for a seamless transition between gears. Felt TTR3 wheels shave weight while offering superior aerodynamics for a bike that works hard to get you to T2. Shimano Dura Ace derailleurs Dura Ace is Shimano’s top of the range groupset and with pro athletes all over the world riding bikes equipped with Dura Ace components, this truly is the professional’s choice. The derailleurs incorporate Shimano’s Vivid Shift technology, with a light but positive feel all the way through the 11 speed drivetrain, giving you the gear you want, when you want it, with the minimum of effort. Aero TT brakes Aero TT Dual pivot brake calipers provide excellent braking power, with angle adjustable pads to ensure perfect pad alignment. A quick release lever aids installation and removal of wheels, for transportation or puncture repairs. Felt and Prologo Finishing kit The Felt Bayonet 3 base handlebar is light but stiff and with its aero profile, it perfectly compliments the advanced aero framset. The Felt aero seatpost with it's split design helps reduce vibrations from the road. It also features 3T DiffLock™ Comfort Module internals. The finishing touch is a Prologo Nago Evo Tri40 T2.0 saddle. The perfect perch for hours in the saddle.
