Anyone upgraded the Brompton unfolding clamp nuts?
I'm talking about the things that hold the frame together when unfolded. It's like a piece of channel iron over a stud, with a washer, then a knob/nut that you tighten/loosen.
I think some people replace the studs with longer ones so they don't accidentally unscrew the knob all the way?
First off I'd like to know what size the stud is (metric/inch, length, thread, etc).
Second, I'm wondering if anyone's replaced the knob with a quick-release mechanism? I think a cam action quick release lever (like for wheels or seat posts) would be great, but I'm not sure how much TRAVEL the quick release gives you... I.E. would it be enough to loosen the channel iron enough to fold the bike.
The other thing I found were quick release nuts, the only problem there is once they're released they come off. Something that released but stayed put would be slightly more convenient
