14T 3-Speed Sprocket/Disc Set, 3-spline, 3/32

14T Replacement sprocket/disc set for 3-speed Brompton folding bikes fitted with a 3-spline Sturmey Archer rear hub. Includes 14-tooth sprocket, rear sprocket circlip (for driver), spacer, and nylon chain-guide-disc.
This can be fitted onto your 3-speed Brompton as a replacement for slightly easier gearing. The current Brompton 3-speed bikes come stock with a 13T sprocket set, so this would be a slightly lower gear.

Cogs and chains wear together!
- If replacing this sprocket we'd expect (and highly recommend) that you also replace the chain.

If you prefer to buy just the 14T sprocket, find that HERE

FYI: While the chains and rear sprockets wear at the same rate and thus need to be replaced at the same time, chainweels (chainrings to us americans) wear slower due to the bigger surface area. You will only need to replace the chainwheels for every 2 (or 3) chains/sprockets.
