Back around 2012, I was told by RBW that the 55 was 700c, and the 54 and 56 were 650b. So you may want to clarify wheelsizes of these frames before you decide.
I'd say get whichever frame is the closest to the standover height and top tube length you are used to and that you know fits you well. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
