Thanks Sammyboy, I'm thinking the 56cm road frames might be a bit too big, how long is the TT on those? Is the geometry relatively tight on them? Maybe you can PM me some specs and pictures? That 531 frame sounds nice, but 52 might be too small.

I sent a message to xrobertomedeirosx on ebay, he's got a nice rossin frame up for bids but it's also a 52cm. God it's a tight bike though, the wheels are practically touching the seat tube and downtube. would be a fun ride.

I'll have a look at the shops too and let everyone know if i find anything, but keep the suggestions coming, i'm excited!

Too bad I can't make brick lane market, i'm only there sunday evening - friday afternoon..
