Hello all,i am about to order a bike online and am unsure on what size to get,my current bike(claude butler hybrid race)is a large,the top-tube measures 56cm and the bottom bracket to top of seat tube is also 56cm,i measured this way as the road-bike i am thinking of getting is also measured like this,i have a 84cm inseam which multiplied by .67=56.28,does this mean i need a 56 frame?The 56 frame on the new bike has a top tube of 55cm and seat tube of 56cm,the saddle on my current bike is set as far back as it can go and to shorten the top-tube seems daft,i am 6ft tall and suffer with mild lower back pain on current bike but legs feel perfect,next size up 58 has 56cm top tube(same as current)and 58cm seat tube,finally the 60 has a 57cm top tube and 60cm seat tube,is it more important to get the top tube length right and just lower the saddle?It seems my legs are a 56 frame and my body is 60,any help greatly appreciated.
