The Shimano Non-turn Washer 7L Grey is a small but essential component designed to keep your internal gear hub axle correctly positioned and secure. Used primarily with Shimano hub gear systems, this non-turn washer prevents the axle from rotating in the dropout under pedaling and braking forces. By locking the axle in the proper orientation, it helps maintain precise shifting performance and protects both the hub and frame from unwanted stress or damage over time.
Finished in a neutral grey color, the 7L washer is easy to identify and match with the correct dropout style on many commuter, city, and trekking bikes. It is an ideal replacement part when servicing your hub, swapping frames, or restoring a well-used bike to reliable everyday performance. Whether you are a home mechanic or a professional workshop, keeping genuine Shimano non-turn washers on hand ensures that hub installations are safe, consistent, and in line with the manufacturer’s recommendations.
