These crankarms are CNC machined in-house from ultra-strong 2024 American alloy. This allows us to remove a lot of material for an elegant design, while retaining excellent strength and stiffness. J.I.S. Square Taper means you can really fine-tune the Q-Factor. 3-bolt Direct-Mount means you can choose from a wide range of chainrings and offset options.
