Sword 1x 40T 165mm Crankset Microshift The Sword 1x crankset is designed for simplicity. 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 to give you the stiffness, chain security, and ease of ownership you expect from a 1x drivetrain. It’s designed to be as compatible as possible: the 24mm spindle is compatible with a ton of aftermarket bottom brackets, and it’s easy to convert from a 1x to a 2x crank by simply installing our 2x chainrings.
