3/6-Speed Axle Hardware -Brompton Kit

Replacement axle nuts and washers for Brompton bicycles fitted with a Sturmey Archer 3-speed rear wheel. Includes parts to fit both pre-2003 Sturmey hubs and today's 3-Speed rear wheel.

Note: The axle on pre-2003 Sturmey hubs (with steel-shell) is shorter than on later hubs, and calls for a short nut (16.9mm), whereas later hubs (with alloy-shell) call for a long nut (19.5mm). Although the difference may seem small, it is essential that you fit the correct nut. Note also that, for Sturmey Archer, a chain-tensioner nut should have a step at the inner end, and an inspection hole (whereas for Sram there is no step or hole).
