hi, i have a load of parts lying around, from upgrades, salvaged from an accident, stock piling or just bought without any need!

i'm thinkng of getting a frame to put all these to good use, but having issues with geometries and sizing.

the frame i am trying to find a similar size to is a cube agree gtc size 60 (more like a 56 in other frames), the effective top tube is 570mm but the reach is only 392mm which seems quite small compared to others i am looking at.

i'm not really able to test the frames (they are online) so what is best to try and match up?

    In very general terms

    The advice I have been given is to cross match STACK and REACH dimensions as the most reliable way of comparing fits. When I had my Retul fit done the fitter explained this to me. Not all manufacturers publish those measurements but most do. The Competitive Cyclist website has quite a good database of geometries for reference. Remember you have some influence over reach by varying stem length.
