What frame have you got at the moment? and whats the wheelbase of your bike (the front hub, to the rear hub) ? Because those two are both rather short at 1000mm and 1005mm, compared to most peoples (mines 1020, and its still a little too short for me). But all in all there both very nice frames! almost the same weight, and the geo isn't all that different. Just theres a £45 price difference, !
