It is also possible to sweat out the rear drops and put in track drops. Check out my site
www.clarkcustomcycles.com and look @ the rattle can racer. It is an Bianchi Team frame and it got two more years of life before it ripped @ the ss/bb joint not my fault. If your bike has forward facing drops you can get away w/ just a track wheel and whatever parts it needs to get running. Good luck fix gears rock.
