Usage
These shims are perfect for riders who need to adapt a 1″ handlebar to a 1‑1/8″ riser, a common requirement in mountain biking, trail riding, and powersports applications. Install the shim between the handlebar and the riser clamp to achieve a snug, secure fit that eliminates wobble and improves steering precision. They are also useful wherever a spacer is required, such as mounting clamps for accessories or custom handlebar setups. Whether you are upgrading an older bike, customizing a new build, or simply need a reliable spacer for a specific mount, the AIRCMT shims provide a straightforward, tool‑free solution.
