Frame - Trek OCLV 5500. I want to put a compact crank on but the braze-on front derailleur won't go low enough for a 50 tooth big ring. It will only get to within a half inch or so.
Any suggestions? Can I modify the bracket in some way? Or is a clamp-on an option instead of the braze-on?

There is something wrong with that picture. My 5200 has plennty of adjustment to get to a 50,with room to spare. There is only about 3/8" diameter diff between a 50 and a 53, meanig the derailer would only have to drop about 1/2 of that. you could file a bit more ajustment into the braze on slot,and if you hose it, I think it just bolts on. If yours bolts on like mine, it could be removd and maybe replaced with a clamp on if the diameter is 13/8" and assuming the tube has enough strength.
