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.

FAQ

What crankset does this fit?

This arm is designed specifically for the Shimano FC-MT101 Altus MTB crankset. It uses a square taper JIS spindle interface and is not interchangeable with Hollowtech II or other interface types.

Does this include the chainrings or right arm?

No. This is a left arm only. Chainrings are riveted to the right arm on the FC-MT101 and are sold as part of the right arm assembly, not separately.

What bottom bracket does the FC-MT101 use?

The FC-MT101 uses a square taper JIS bottom bracket. The appropriate BB depends on your frame's shell width (68mm or 73mm) and the required spindle length -- check the Shimano compatibility chart or consult a shop for the correct BB specification.
