I want to buy a £1000 bike, using Cyclescheme vouchers, ideally from someone local to me in SW London.

And I'd like to test ride a few bikes before buying one. The problem is I'll want a small (around 51-52cm TT) frame. I've done a bit of calling in to bike shops and phoning importers with no luck finding one so far.

Does anyone have any advice for me?
