IRD Alpina-d Compact Road Triple Front Derailleur
http://harriscyclery.net/product/ird-alpina-d-compact-road-triple-front-derailleur-2435.htmIf you can give Harris Cyclery the business, even better. They're a great shop - one of the best. Rivendell stocks it as well (with the clamp sold separately) - also a great shop to support.
I think a Sora 9 spd front derailleur
might work, as well. That's what I run on my 10 spd triple road bike, though I have the front set up for friction, not indexing.
