Sorry if this is a rather basic question but as regards sizing on a bike is the effective top tube the best measurement to go by. I guess what i am asking is if 2 bikes, both hardtails, have the same eff top tube what else would effect how well the bike fits – head angle/seat tube angle etc.
I know that the answer if possible is to try out bikes but sometimes that isn’t always possible.
Second more specific query is to do with inbred/scandal frames. A lot of people on this forum say they are long in the TT. The geometry from the on one site –
C Effective Top Tube Horizontal (mm) 546 589 602 612
so the 18″ is 602 and the 20″ 612. But this doesn’t strike me as very long eg. the Cotic is 610 in a 19″ (only 2 mm short of the 20″ inbred). And the rockhopper is 615 for a 19″.
I found a thread (can’t find now) where it suggested that the on one measurments above were actually not effective ie. headtube horizontal to where it intersects the seatpost but actually headtube to top of seat tube which isn’t horizontal. Can anybody shed some light on this ?
thanks for any an all replies
