Shimano MT520 Crankset 12V 170mm 30T - Black

This MT520 crankset from Shimano is expertly crafted for compatible 1x12-speed MTB drivetrains, perfect for trail and enduro bikes. The 170 mm aluminum crank arms feature a robust two-piece construction with a 24 mm steel axle, while the 30T four-arm steel chainring incorporates Shimano's Dynamic Chain Engagement+ narrow-wide tooth profiling, ensuring the chain remains securely engaged even on rough terrain. The 30T chainring is an excellent choice for riders seeking easier climbing gears compared to a 32T or 34T setup, particularly on steep trails, technical climbs, or when riding with a load. Before placing your order, please verify the frame's bottom bracket shell, chainline, rear drivetrain, and required bottom bracket, as the bottom bracket is not included.
