Shimano Nexus 8 Stop Ring

This Shimano Nexus 8 stop ring is a small yet essential internal component for Nexus 8-speed hubs, securely locking the ring gear unit in place within the hub mechanism. By ensuring the ring gear is properly seated, it aids in maintaining precise indexing, quiet operation, and reliable shifting over countless kilometers of city, trekking, and everyday riding. When the original stop ring is worn, bent, or lost during a hub overhaul, replacing it with this genuine Shimano piece restores the secure fit that the hub was designed for.
