Description
Shimano Altus FC-M311 Mountain Bike Crankset
Engineered for rugged trails and versatile performance, this triple-chainring system delivers reliable power transfer across mixed terrains. The Hyperdrive SG-X chainrings feature hardened tooth profiles for reduced wear and smoother gear shifts during climbs or descents.
Integrated Protection & Durability
A full-coverage chainguard is seamlessly built into the crank design, shielding chains and derailleurs from debris on muddy singletracks or dusty fire roads. The black anodized finish resists scratches from frequent off-road use.

– Square taper JIS spindle (9/16″ pedal interface)
– Works with 135mm rear/142mm front MTB hubs
– 170mm crank arm length optimized for balanced pedaling
Ideal For
– Cross-country riders needing lightweight durability
– Trail enthusiasts tackling root-heavy descents
– Urban commuters seeking low-maintenance city-ready components
