Shimano Zee M645 10 Speed Crankset

Durable, reinforced crankset - the thick wall aluminum construction on the Zee twopiece cranks and reinforced steel axle translate to additional confidence on the trail.

With an axle 30% stronger than comparable trail cranks and smooth running, accurately aligned chain wheels, the Zee crank will perform reliably - run after run. The crank arm features outboard bearings and steel pedal inserts.

Shimano introduces Zee, a new line of gravity components that are an ideal starting point for aggressive riders and racers. Zee is the gateway gravity component line that allows riders to get on board with Shimano’s gravity program and experience premium new component technologies at a price they can afford.

Please note, external Hollowtech II Bottom Bracket is included.
