The Shimano Zee FC-M645 Crankset 1 x 10 Speed w/Bottom Bracket For 83mm Shell (57.9mm Chainline) are 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.
