Cane Creek Square Loc Axle Max Stiffness, Precision Steering If you are running the Cane Creek Invert Enduro suspension and seeking maximum torsional stiffness, the Cane Creek Square Loc axle is a no-compromise upgrade. The 20mm Square Loc axle keys directly into the fork dropouts and is secured by four pinch bolts, which eliminates unwanted flex and provides a more planted, precise feel on steep and high-speed terrain. This setup allows heavier riders and e-MTB users to fine-tune the fork's stiffness characteristics to perfectly suit their riding style and terrain.
