I have a Lemond Victoire road frame with sloping top tube. Size is a 53. (this is the same geometry as the Zurich).
I want to build up a Propad as a cross bike, but I am not sure which size to get. It is available in a 52 and a 55. It does not have the sloping top tube geometry.
I have been told that with the Propad's geometry it is adviseable to get one size up from what you normally ride with the sloping tube geometry which would be the 55 for me (the sizing skips from 52 to 55 and is not available in a 54).
What do you think? Which would be more appropriate?
My concern with the smaller frame would be that the top tube may be too short.
thanks for your help
