I bought this bike in May 2013 and have used it as my training bike. Unfortunately I haven't really ridden it since October last year due to injury which has prevented me from cycling regularly. The bike hasn't been modified in any way other than changing the hand bar tape from white to black. Lightweight aluminum frame with Shimano 105 groupset. Mavic Kysrium Wheelset. Ritchey bars and stem. Size Small (53cm) The tyres, chain, cassette and cables were all replaced in May this year and have only really seen 150 miles or so as I had to stop cycling again. The frame has a few scuffs on it from general use. Overall a great light, fast bike which has been faultless. Sold with an extra wheelset (Mavic Askium's) intended for winter use. Note water bottle, mud guard and computer mount are not included.
