Shimano FC-MT101 Left Crank Arm - 175mm | Black
What Is the Shimano FC-MT101 Left Crank Arm 175mm a Replacement For?
The FC-MT101 left crank arm in 175mm black is the OEM replacement left-side arm for the Shimano FC-MT101 entry-level mountain bike crankset. This is a left arm only, sold as a service part for builds where the original has been damaged, bent, or lost. The arm uses a square taper JIS bottom bracket spindle interface, the same standard found on a broad range of Shimano entry to mid-level cranksets, making it a straightforward drop-in replacement for any FC-MT101 installation. Shimano manufactures it to the same geometry and torque specification as original equipment, so chainline and Q-factor remain correct when installed.
At 175mm this is the standard longer length for the FC-MT101, suited to trail and XC MTB riders who prefer a longer crank arc for technical climbing and power on punchy singletrack. The black aluminum finish matches the original crankset aesthetics. This arm does not include pedals or a bottom bracket, and is specifically for the left (non-drive) side only. The FC-MT101 is a widely used entry-level MTB crankset compatible with 6, 7, and 8-speed systems, and replacement arms are frequently needed after rock strikes or crashes. For FC-MT101 owners needing a direct OEM left arm replacement, this is the correct 175mm part.
