Overview

The Avid SRAM Rotor Shim is a precisely engineered 0.2mm stainless steel spacer designed to sit between a disc brake rotor and an ISO 6-bolt hub. Its purpose is straightforward but important: by adding a small, controlled offset to the rotor's position, it allows mechanics and riders to fine-tune rotor alignment relative to the brake caliper. This eliminates or reduces brake rub, uneven pad wear, and the annoying noise that results from a slightly misaligned rotor — issues that are common after wheel swaps, hub servicing, or when mixing components from different manufacturers.

Made from stainless steel, the shim is built to handle the clamping forces of rotor bolts and the heat generated during braking without deforming or corroding over time. At 0.2mm per shim, adjustments are intentionally subtle, giving you granular control over rotor placement. Multiple shims can be stacked when a greater offset is needed. Sold individually, this approach lets you purchase only what your specific setup requires, making it a practical and inexpensive addition to any bike mechanic's parts bin.

Pros & Cons

👍 Pros

  • Precisely machined 0.2mm thickness allows very fine rotor alignment adjustments.
  • Stainless steel construction resists corrosion and withstands braking heat.
  • Compatible with the widely used ISO 6-bolt hub standard.
  • Sold individually so you can buy exactly the number you need.

👎 Cons

  • Sold as a single shim, so achieving larger corrections requires purchasing multiple units.
  • Only offers a 0.2mm increment, which may not be enough for significantly warped or misaligned setups.
  • Small size makes the shim easy to lose during installation.
  • Only compatible with 6-bolt rotor mounts, not centerlock hubs.

Frequently Asked Questions

It sits between the rotor and the hub to make fine adjustments to rotor position, correcting minor alignment issues that cause brake rub or uneven pad contact.
It is designed for ISO 6-bolt disc brake hubs, the most common mounting standard on mountain bikes, gravel bikes, and many road bikes with disc brakes.
This product is sold individually, so each purchase includes one 0.2mm shim. You can buy multiple if you need to stack shims for greater offset.
It is made from stainless steel, which resists corrosion and maintains dimensional stability under the heat and clamping forces of disc brake operation.
Yes, you can stack multiple 0.2mm shims to achieve a greater offset if a single shim does not provide enough correction.
