while the clipless issue has come up in passing, I can't recall a thread devoted to the idea and the choices open to a would be cliplessee on a folder.
Me, I bought a secondhand Speed TR with powergrips, and found I really liked the extra pull they gave me, and am now thinking of going one better, and clipless, on a forthcoming Brompton S2L-X, and maybe on the TR. But there are different kinds of clipless right ? And Double sided and single sided? Are there some better for folding ? Etc.
