I've got an aluminum frame bike with a triple and a clamp-on front derailleur and I'm considering converting it to a standard double, but in the off-season I'd want to switch to a compact crankset, so I'd rather I was able to use a braze-on derailleur instead. Anyone ever use an adapter like pic related?

Otherwise I imagine I'd have to take the whole bike to a frame builder and have them weld the tab on instead.
