Clunking Brompton pedal -- and it's new!
I was tormented by a clunk in my folding pedal, so I replaced it with the new model, the one that goes on with a big allen wrench instead of the old, huge socket.
The clunk persisted, even louder, every time the left crank arm went over the top. It sounded like a ball peen hammer on an anvil. So I tore it down to and including the bottom bracket, regreased everything and reinstalled. Still clunking.
Just on a hunch -- and because I was out of ideas -- I replaced the new folding pedal with a spare non-folding pedal I had lying around. Clunk gone.
So, anyone have any brilliant ideas on how to banish this from the new folding pedal? Or is it just defective?
Thanks in advance,
