about disc brakes at the rear

There are ways to do this, but they aren't cheap. Hope this lets you get to 2 of the options. http://myweb.search.yahoo.com/myresu...Fmyweb&fid=181. There is a cheaper option on eBay. I'll try to find it again. http://sporting-goods.search.ebay.co...Z1QQsofocusZbs I'm not sure I would go the cheap route. My concerns are that if the bike frame was not designed for disc brakes, these could put an awful lot of stress on the seat stay at a point that it might not be able to handle it. I would talk seriously with an experienced bike mechanic that has had a chance to look at your frame before going that way. The Therapy and Woodman adapters get around that concern, but at such a cost that unless you can't find a frame to fit you that has disc brakes, it would be cheaper to buy a new frame rather than build new wheel and buy those adapters.
