Shimano MT520 Crankset 12V 165mm 32T - Black

This MT520 crankset from Shimano is designed for compatible 1x12-speed MTB drivetrains used on trail and enduro bikes. The 165 mm aluminum crank arms utilize a two-piece construction with a 24 mm steel axle, while the 32T four-arm steel chainring features Shimano Dynamic Chain Engagement+ narrow-wide tooth profiling to help keep the chain securely engaged on rough terrain. The 32T chainring provides a balanced gear choice for mixed trail riding, while the shorter 165 mm crank length can assist with pedal clearance on technical sections. Be sure to check the frame bottom bracket shell, chainline, rear drivetrain, and required bottom bracket before ordering, as the bottom bracket is not included.
