Sturmey Archer Gear Ring HSA443
- EAN 4710944229332
- Brand: Sturmey Archer
- Product Model: 123305
This Sturmey Archer gear ring is the complete gear ring assembly used in modern 3-speed NIG (No-Intermediate-Gear) hubs, forming the heart of the planetary drive system. It carries the internal teeth that mesh with the planet gears, so a worn or damaged ring can lead to rough running, noise, or slipping when you pedal. Replacing it with this genuine assembly restores clean engagement and smooth, efficient drive on city, touring, and everyday bikes that rely on Sturmey Archer 3-speed hubs. Used in a wide range of current Sturmey Archer 3-speed hubs such as S-RF3, TS-RB3, X-RD3 drum brake, and SRK3 cassette-type hubs, this complete unit lets you rebuild the internal mechanism correctly instead of guessing with non-original parts. It’s a smart choice during a full hub overhaul or when you’re bringing a well-used commuter or utility bike back to full health for reliable daily riding.
