I'm rebuilding a friend's Richard Sachs with a new Record triple group. Everything was fine until I
got to the front derailleur. It's a braze-on model, and I can't get it high enough to clear the 52
tooth outer ring. It is about 2 mm too low at the top of the slot. I'm trying to get my friend back
on the road quickly. I guess I could switch to a 50 tooth ring, but that wouldn't be the best
solution for him. If I file the slot, I'll only have about 2 mm of metal left at the top. I don't
like that idea, but would that be enough? The old derailleur is a 1991 Athena. It does clear the
ring, and it has enough range to cover three rings, would it work with Ergo and a triple? The cage
is narrower, so I assume it would require more trimming. Perhaps more important, the inner cage
plate doesn't drop down as far. Would that seriously compromise shifting? My friend is looking for
simplicity, not a science project every time he shifts.
Thanks
