Replacement sprocket/disc set for the Brompton BWR or 1/2-Speed Rear Wheel. Includes 13-tooth sprocket, rear sprocket circlip (for driver), spacers, and nylon chain-guide-disc.
This sprocket is NOT a 3-spline, but rather a 9-spline. It would be used on a BWR hub, or on a Brompton 1/2 speed hub. It is not a typical 3-spline cog that you expect to see on a Brompton 3 speed bike.
If this is out of stock, you can get the individual sprocket HERE
If you are replacing this sprocket, it is highly recommended that you also replace the chain as the sprocket and chain wear together and become a matched set over time.
