The Shimano FC-M7130-1 SLX is a 170mm, 12-speed crankset built for modern mountain bike drivetrains. A hollow forged crank arm improves power transfer while keeping weight down, and the direct mount chainring interface creates a stiff, reliable connection between crank and frame.
An aluminum crank arm and two-tone black finish keep the crankset light without sacrificing durability, while the Hollowtech II spindle interface pairs with a matching bottom bracket for a secure, low-maintenance connection. Built to Shimano's current 12-speed mountain bike spacing, the crank swaps into compatible SuperBoost+ drivetrains without extra hardware.
