Head tube cable guides look nicer in my opinion. Is there a practical reason to choose them over down tube guides or vice versa?
Down tube stops are a hangover from when the shifter mounts were adapted, with the advent of integrated brake lever shifters.
If the stops are mounted too high on the head tube the cable could foul the DT, but the frame builder should be aware of that.

So we tweaked the geometry a bit (head angle now 71,5 degrees and fork rake 50 mm) and managed to stretch front-center by 10 millimeters with only -2 mm change in trail. Looks like that solved the toe overlap problem.
It’s now down to two decisions:
1) 31,7 vs 35 mm down tube
2) head tube vs. down tube cable guides
Is a smaller diameter tube more resistant to dings even with similar wall thickness? Would a 35 mm down tube on a bike like this be an overkill for a 75 kg rider and add excessive stiffness?
