The Sword Black 1x crankset is designed for simplicity and exceptional value.
With a single, chain-retaining ring mounted to the crankset’s outer ring position, it pairs perfectly with the rest of the Sword 1x drivetrain.
Sword Black cranks are suitable for use with a square taper bottom bracket axle (not included). This crank uses the same chainring standards as the original Sword but adds a new lower price point.
