Overview

Is the Shimano STEPS FC-E6000 Left Crank Arm the Right Replacement for Your E-Bike?

The Shimano STEPS FC-E6000 Left Crank Arm is the OEM replacement left arm for the FC-E6000 e-bike crankset used on Shimano STEPS E6000 series city and trekking drive units. This arm uses a square taper JIS spindle interface with a diamond-orientation spindle hole, the correct spec for the E6000 drive unit, which is not interchangeable with Hollowtech II or other standard MTB crank interfaces. If your left arm is damaged, cracked, or stripped at the spindle, this is the confirmed factory part to return your e-bike drivetrain to spec without replacing the entire crankset.

170mm arm length. Sold as left arm only. Mounting hardware, dust cap, and right arm not included. Designed for city and trekking e-bike use. MPN: Y1R201000. Black finish.
