Shimano FC-MT101 Left Crank Arm — 175mm, Black

The Shimano FC-MT101 left crank arm is a durable, no-nonsense replacement designed for entry-level mountain, hybrid, and commuter bikes using Shimano 2-piece cranksets. It’s a common service part for bikes that have suffered pedal strikes, crank damage, or stripped pedal threads.

Built from forged aluminum for strength and reliability, this crank arm uses Shimano’s proven Hollowtech II interface, ensuring a secure fit and long service life. At 175mm length, it’s ideal for riders who need to restore proper crank length and fit without replacing the entire crankset.

This is a straightforward, mechanic-friendly solution when only the left arm needs replacement.
