Now, without stealing the original purpose of this thread, besides a highly modified Brompton, what are my choices?
A modified Mezzo?
Putting short bull bars on mine with road STi brifters worked great. Folds a bit bigger ,but I have found a good compromise,than does not effect my commutes.
Then I went for dual drive to address getting some high gears.
Brakes, get a D10 with rear V brake, braze on some V mounts, or just go for telfon cables and Koolstops.
