Avid Disc Post Spacer Kit

This kit allows you to upgrade to a larger brake rotor without replacing your entire brake caliper or fork. It provides the necessary spacing to align your existing post-mount caliper with a bigger rotor size.

No, this kit is specifically designed for post-mount systems. It will not work with flat-mount or IS (International Standard) mounts.

Titanium is used to provide a high strength-to-weight ratio. It ensures the bolts are durable enough to handle the intense heat and stress of heavy braking while keeping the overall weight of your bike as low as possible.

You need to match the kit to the difference between your current rotor size and your new, larger rotor. For example, if you are moving from a 160mm rotor to a 180mm rotor, you need the 160 Post to 180 Rotor kit.

You will need a standard set of hex keys (Allen wrenches) to remove your caliper, install the spacers, and re-secure the bolts. A torque wrench is highly recommended to ensure the bolts are tightened to the manufacturer's specifications.

When installed correctly, these spacers ensure precise caliper alignment, which is critical for consistent, rub-free braking. The performance gain comes from the larger rotor itself, which offers better heat dissipation and increased stopping power.
