• Isn't the thing with reach is that... it's measured from the BB center.

    Which means that two frames with the same reach will have different 'virtual tts', or 'actual real world reach' if their seat tube angle is different.

    Is this what you are referring to as poor frame design?

    Also I notice that the chainstay length on the larger frames is slightly longer, so is it possible that the BB is pushed forward to further increase the 'real world reach'?

  • good point, hadn't noticed the seat tube angle change

    though given the set back for a saddle is measured in relation to the bottom bracket simply setting the saddle further back by having a slacker seat tube does not actually resolve the fit issue.
