Jagwire Disc Brake Shims

No, these shims are specifically designed for 6-bolt rotor systems. They are intended to sit between the hub and the rotor to adjust spacing, which is not applicable to the Centerlock mounting standard.

Shims are primarily used to correct rotor alignment issues, such as when a rotor rubs against the brake pads despite proper caliper adjustment. They can also be helpful if you are swapping wheels and need to match the rotor position across different hubs to avoid re-centering your calipers every time.

You should use only as many as necessary to achieve proper alignment. Typically, one or two shims per bolt are sufficient to correct minor spacing issues; using too many can compromise the security of the rotor bolts.

No, these are constructed from stainless steel, which is highly resistant to corrosion and wear. They are designed to withstand the elements and maintain their integrity even in wet or muddy riding conditions.

No specialized tools are required beyond the standard Torx or hex key you already use to tighten your rotor bolts. Simply place the shim over the bolt hole before mounting the rotor.
