I've noticed some roughness and noise when freewheeling on the (6sp) Brompton. This happens in all of the three hub gears so I assume is something to do with the freewheel setup.
I was under the impression that these had some weird dual-freewheel setup whereby this facility exists in both the hub and a freehub onto which the sprockets are fitted - can anyone please confirm that this is correct?
I'm reasonably happy stripping / inspecting / cleaning / relubing a freehub; less-so the 2sp hub itself...
Any resources on this would be much appreciated
Ta!
