Campagnolo Bullet Ultra 11 Speed Carbon Chainset. • Featuring USB™ ceramic ball bearings, the new Bullet Ultra cranksets are engineered for minimum friction and rolling resistance. • The cranks and chainring mounts are a single element. The result is an extremely stiff crankset for maximum performance and efficiency. • The Bullet Ultra chainset is manufactured from uni-directional carbon fibre which makes for a light and stiff chainset that maximises the power transfer to the road with unparalleled aerodynamics. • Full carbon fibre spider: the unique shape of the chainring mount is specifically designed for maximum aerodynamic efficiency while also increasing the overall stiffness of the chainset. • XPSS(TM): Exclusive design of the eight up-shift zones and two down-shift zones of the chainring. The specific profile of the teeth and the zones dedicated to upward and downward chain movement enables fast and precise shifting in all conditions. • Power-Torque bottom bracket: System with single axle designed to maximize stiffness and power transfer. • Lightweight carbon construction • 11 speed specific • Streamlined unidirectional Carbon fibre for extra strength • Full-carbon unidirectional-multidirectional cranks - hollow cranks (Ultra-Hollow™ Structure). • Light alloy fixing bolts - light alloy chainrings with XPSS™ (eXtreme Performance Shifting System). • Chainrings with hard anodization treatment - 8 pins on the large chainring. • USB bearings (Ultra Smooth Bearings). • Integrated ULTRA-TORQUE™ semi-axles. • Requires ULTRA-TORQUE™ BB cups. • Available crank lengths : 170, 172.5, 175mm. • Available chainring configurations : 34/50 36/52 39/53. • Weight : 815 gms.
