How tall are you? I can't find any recommendations online re. sizing but the geometry chart makes it look fairly big for a 56cm. . . what's the effective tt? Also just to confirm does the frame take a BMC-specific seatpost which I'd need to buy separately?
What counts as a silly offer? Also where in London are you based? I might be able to pick it up tomorrow depending on where you are and figuring out how much I can stretch to
Nice... guessing it's gone?!
