I am trying to design my first frame and I am curious about the decision criteria for locating cable stop braze ons.
I have seen them on top of the top tube, on bottom of the top tube and on bottom of the down tube. Is this purely asthetics or are there some design considerations to the location of the cable stops?
For reference I am designing a bike for touring and my preference would be to run all the cables down the bottom of the down tube so that I can strap a bag to the top of the top tube and use the bottom of the top tube to mount tent poles or possibly an extra water bottle.
I would appreciate any help with understanding the decision criteria for locating the cable stops.
Thanks in advance
