Brompton 3 speed axle nuts/washers for STURMEY ARCHER hub

Brompton Sturmey Archer hub - fixing kit

This set of nuts and washers includes tab washers for alloy shell Sturmey Archer wheels, as well as alloy shell chain indicator nut (the one with the hole drilled in the side) and chain tensioner nut / washer

Compatible wheels (with the complete set):

Brompton BSR - Standard Ratio - 3 speed wheel
Brompton BWR - Wide Ratio - 3 speed wheel (as used on 6 speed bikes)

Technical notes:

Tab Washers:
This pack comes with two tab washers
If you are just after the tab washers - they are Sturmey Archer code HMW526 and available individually

Axle nuts:
These must only be used on Sturmey Archer hubs, if used on SRAM/Brompton single or two speed hubs they may start to fit then strip the thread -  so don't do it!

Chain tensioner / gear indicator nut:
(This is the nut with a hole in the side)
Later hubs (normally with alloy shell) use the longer (19.5mm) nut - included in this set
The difference may be small - but it is essential to use the right one.

Note: On pre-2003 Sturmey Archer hub (with steel shell) there was a shorter (16.9mm) nut - since 2017 this is no longer included in the pack
