Hi guys, I'm thinking of converting an old Trek 720 (maybe 820?) multi-track hybrid into a cyclocross/road/commuter bike that is ss/fixed and I am wondering which style of dropouts would be best for a mostly road ss, campy or rear facing horizontal? What are some of the pitfalls, or things I should watch out for once I decide which dropouts are best. I'm a machinist and a couple of my friends are excellent welders, but I've never cut up a bike frame before, so any tips or tricks would be appreciated. It's a steel frame with 700c wheels and I know I may have to spread the rear stays depending on my hub choice, if that helps. Also, any hints on modifying cranks and rim choice (cxp33?) would be great. I would like to keep it relatively inexpensive.
