Not that I am operating out a modern assumptions of knowable truths, or a belief in a platonic form of bike size.
Just wondering what the popular theories are - do you use an MTB frame with measurements close to that of your road frame?
Many MTBs seem to have sloping DTs- would this mean finding a much larger than normal road sized frame?
Do you say 'screw it' and just use taller seat posts...?
