I have an 02 Lemond, steel frame, Ultegra 9-speed bike that I have considered converting into a cross bike. It would be nice to have something to cruise the hood with my son and be able to hit some mello dirt with him now and then. Is this feasable and what kind of mods would I be looking at. Wheels? Fork? Brakes? Here's a pic of an 02. Not mine, but exactly the same.
