Customer Reviews

The Nitto Stainless Shim is a small conversion part designed for fitting a 25.4mm handlebar into a 26mm stem clamp.


On vintage steel bikes, Japanese components or older handlebar and stem setups, it is common to find a size difference between 25.4mm and 26mm clamp standards. If the handlebar diameter is smaller than the stem clamp size, direct installation may result in poor clamping, slipping or an insecure fit. This shim fills the gap between the handlebar and stem, helping create a more stable installation.


Made from stainless steel, this shim is 0.6mm thick and weighs approx. 8.5g. The silver metal finish is clean and subtle, allowing it to blend naturally between the handlebar and stem without affecting the overall cockpit appearance. It is a useful small part for restoring vintage bikes, building with Japanese components, setting up single speed bikes or matching Nitto bars and stems.


To use, place the shim between the handlebar and stem clamp area, then tighten the stem properly. After installation, always confirm that the handlebar does not rotate or slip, and check the clamping condition again before riding.


If you need to fit a 25.4mm handlebar into a 26mm stem, the Nitto Stainless Shim is a simple, practical and well-made solution.


⚠️ Please note: this product includes the shim only. Handlebar, stem and display props are not included.
⚠️ This product is designed to convert a 25.4mm handlebar for use with a 26mm stem.
⚠️ Please confirm handlebar and stem clamp size compatibility before purchase.
⚠️ After installation, make sure the handlebar is securely clamped and does not slip or rotate.
⚠️ Cockpit components affect riding safety. Professional installation and inspection are recommended.
