[QUOTE=Gattonero;579846]Small frames are blessed by braze-on FD, however this may limit the choice in case of triple ch/set or groupset.
Worst case scenario, a few washers (or even Presta valve washers) would step-away the ST bottle cage with minimal fuss

Yes, I'm aware of those new fangled (joke) braze on front derailleurs but the person that was paying me to make those frames doesn't like them. So as any good contract builder would do I built the frames to the spec of the person writing the check. My comments weren't about how to make this or that work. It's just a comment of what I did in the past as a contract builder.
