Product Description
The Shimano Altus M311 crankset is a practical replacement for older mountain bikes, hybrids, and comfort bikes running a triple 7/8-speed drivetrain. Built around a square taper spindle interface, it offers broad compatibility for many common bikes and is an easy choice for getting a worn drivetrain back in service.
This 175mm 22/32/42T setup includes a chainguard and uses Shimano’s Hyperdrive chainrings for smoother, quieter front shifting across a wide gear range.
