Centerlock Rotor Shim (4 pack)

These disc brake shims install between the rotor and centerlock disc brake hub allowing you to fine-tune the alignment of the braking surface. Shims are commonly used when swapping between different brands of wheelsets, so that you don't have to re-align the caliper on the frame. We recommend a maximum of four per hub. They are .25mm thick, four per order. Pre-cut for easy installation.
