I wish I had those brakes on my Flamingo (Merc) BP01-3. It has pretty poor caliper brakes, although I can get along with them now. V-brakes would be far better. Anyway - You are obviously well aware of the flamingo rip off series, and you obviously don't need to save money if you are thinking about titanium Brompton parts. I'd really like a Brompton 6 speed in raw laquer like Mulleady has (I think his is a six speed). It's a very pretty bike, but I can't bring myself to chuck that much cash at a bike more or less functionally identical to the cheaper one I have had for two and a half years. I've had great service out of it.

By the way, it folds oK and is the same dimensions as the B as far as I know. I wonder if the seven speed hub makes the bike wider when folded? I think they may be wider than the wonderful SA SRF3 - I love that hub it will probably do a million miles - my knees won't though so someone else will need to take over and do the rest when I fall over and croak.
