QUOTE (danny B @ Mar 7 2008, 09:00 PM) <{POST_SNAPBACK}>the main changes are the bolt through rear axle which will improve rigidity and the weight, the bike is almost 200 grams lighter!!!!!!! now weighing in at 1.65kg!!!! Cool, good stuff Danny . Does the frame have to be used with certain hubs then? I take it the actual axle must locate in the dropouts somehow before bolting up...
