Is the Shimano FC-MT101 Left Crank Arm the Right Replacement for Your MTB?

The Shimano FC-MT101 Left Crank Arm is the OEM replacement left arm for the Altus FC-MT101 3x9-speed MTB crankset, using a square taper JIS spindle interface that fits standard MTB bottom brackets. If the left arm on your FC-MT101 crankset is cracked, stripped at the spindle, or damaged from an impact, this is the correct factory part to return your drivetrain to spec without replacing the full crankset. At 175mm, it suits the taller arm length spec used on Shimano Altus entry-level MTB builds.

Sold as left arm only -- chainrings, right crank arm, and bottom bracket not included. Compatible specifically with the Shimano FC-MT101 crankset. MPN: Y0G403100. Black finish.
