Designed for riders seeking reliable 1x performance, the Shimano Deore FC-M5100 30T crankset delivers smooth power transfer and long-term durability for 10- and 11-speed mountain drivetrains.
Its two-piece construction balances stiffness and weight, ensuring responsive pedalling across technical climbs and fast-flowing singletrack.
The 4-arm 96mm PCD chainring maximises drivetrain efficiency, while the 52mm chain line and 178.5mm Q-factor provide confident handling and optimal chain retention on wide-range setups. Compatible with both 141mm QR and 148mm thru-axle rear spacing, this crankset suits a wide range of modern MTB frames.
