What are the exact specifications of the nuts used on the various axles of the Brompton bicycle?
Specifically, I have a 2016 M6R black, but I would appreciate it if you listed the specifications for all models for others as well.
I'm currently bikepacking through South Asia verrry far from a brompton shop. My axle nuts are rounding out, and I'd like to replace them and get some spares as well. Unfortunately, the local shops have nuts too small for my wrench and--worse--I don't know if the threading is slightly off from the axle.
This information was glaringly absent from the specification & schematic docs on the brompton website, but it does mention that the threading may be off between different rear axles, depending on the Sturmey Archer hub installed:
Can you please list the nut:
- nut size
- thread pitch
- flat-to-flat width (for wrench size)
- pitch-to-pitch width
- anything else I should know to buy this nut from a third-party
