I've got a Pelizzoli Corsa GP lugged-steel, road frame that I ordered last year, and love it. It's well made and a thing of beauty.
It also has one problem. Apparently a few of these frames were produced with the front derailleur mounting fixture brazed on a bit too low. I assume the fabrication jig was positioned incorrectly, or something like that.
It's not the end of the world, of course, but it is a small hassle. Anyway, the tab is 140 mm from the center of the bottom bracket to the center of the tab's slot. On another road frame in my collection, the tab is positioned at 150 mm from the B/B.
My question is, rather than go with a compact crankset, I'd like to simply use a reduced tooth count chainwheel - as opposed to the the 'standard' 52 ring.
I'm building up this frame using vintage Campagnolo Super Record equipment, so I'm thinking a 50-tooth chainring may do the trick, and allow the derailleur to clear the slightly smaller ring for proper function.
Before I go and order this chainring, do you guys think this solution will do the trick?
Any suggestions would be appreciated...
