With Shimano's Ultegra SL Crankset you get Pro Tour-worthy pedal power and you don't need a Pro Tour budget to afford it. This great crankset boasts Shimano's Hollowtech II technology, which features hollow cold forged-aluminum crankarms for excellent weight savings, stiffness and strength. Plus, the oversize bottom-bracket axle and outboard bearings (sold separately) provide super-efficient power transfer and the chainrings boast Shimano's Hyperdrive design for super fast and smooth shifting.
Note: the Ultegra SL Crankset comes with an integrated bottom-bracket axle. Bottom-bracket cups are sold separately.
