Cranksets

For maximum pedaling efficiency, Shimano's 105 Compact Crankset boasts light, strong and stiff hollow, cold forged-aluminum arms, plus an integrated oversize-steel axle. The compact chainrings are also made of cold-forged aluminum and are ramped and pinned for quick, precise shifting.

Shimano's Claris Crankset makes it easy to find the right gear. Lightweight, stiff aluminum crankarms provide excellent power transfer, while the ramped and pinned chainrings boost shifting speed and precision.

Super strong and ultra durable, Shimano's ZEE Cranks are tailor-made for aggressive riders, DHers and dirt jumpers that don't have endorsement deals. They use a 2-piece design with solid aluminum arms as well as a steel axle and steel pedal inserts for longevity. Stiffness was put at a premium, so if you need to stomp on the pedals to get up to speed quickly, or if you're a Clydesdale who punishes lesser cranksets, ZEE has your back. It's 10-speed compatible and is equipped with a 36-tooth chainring. The bottom bracket is included, too.
