Brompton Twins?

A lot has happened/changed in 2020 & our Brompton front is also rather different now.

Lots of tinkering has seen both Clarence & Peregrine swap from S6R models into lightweights with 3speed external gearing. Peregrine has lost about 3kg (now weighing 10kg) but Clarence has seen a bit more work in getting down to 8.7kg. Everything is running smoothly & delightfully after all the part sourcings & conversion work.

We also have 6speed lightweight twins (of sorts), after Rudolph has been joined by Ruby, a S6L-XD version that was obtained late-2019 in grey livery. Unfortunately the mainframe hinge had an issue & Brompton Australia (ta) obtained a replacement frame in House Red colour (grey no longer being available).

Having gained skills in rear frame & fork replacement, headset changes & external gearing tweaks, I’m figuring that wheel building skills ought to be next? How hard can it be? I’m nearly ready to go…

    Can you explain more what 3 speed external gearing is?

      Hi Jerry,
      A Brompton 2 speed freehub that has an extra gear, as compared to a Brompton 3 speed IGH (internally geared hub). The word external is commonly used although I’m irked by it but in thinking about it, freehub is probably the more correct? (Must remind myself to stop using “external”.)
