Ok, so this may be a dumb idea but I thought I would ask.
I'm going to re-lace a Zipp 404 tubular wheel that I have. It's got a Tufo tire glued on right now, and I don't feel like taking it off. Would it be a stupid idea to try an build the wheel with the tire still on? It uses external nipples.
I guess I'm just trying to cut a corner here.
Also, I got some help with the spoke calculation from the Zipp online help chat. The rep said that they don't recommend re-lacing pre-built rims because it hastens failure. Is that just an overly cautious disclaimer to avoid any liability? or is it actually a bad idea to rebuild the rim?
