Shimano Altus FC-M311 Crankset - 170mm | 7/8-Speed | 48/38/28t
What Does the Shimano Altus FC-M311 Crankset Offer?
The Shimano Altus FC-M311 is a 3x crankset designed for 7 and 8-speed mountain and hybrid drivetrains, combining aluminum crankarms with a 48/38/28t triple chainring setup that covers the full range from granny gear climbing to flat-out spinning. The chainrings are made from steel SG-X material, which provides reliable shifting ramps and durable tooth geometry that holds up to the chain engagement demands of budget and mid-range drivetrains. At 170mm arm length, this crankset suits most rider heights and delivers a comfortable, efficient pedaling position across terrain types.
The FC-M311 uses a square taper JIS bottom bracket interface, which is a widely available and easy-to-service standard found on most entry and mid-level mountain bikes. It pairs correctly with Shimano 7 and 8-speed front derailleurs in the Altus, Acera, and compatible tiers. If you're building or maintaining an affordable trail hardtail, commuter, or multi-purpose mountain bike, the FC-M311 delivers the broad gear range and reliable performance the platform demands without adding unnecessary cost.
