At the risk of sounding (demonstrating that I am) obtuse and definitely demonstrating that I am lazy, how hard would it be to build/obtain a set of road and cross wheels (one of each) with the disc? I would *never* swap disc and cantis back and forth. If I went to disc, I'd stay there. It's all I can do to clean my bikes and pump up the tires. I would be happy to have this be my forever bike for cross and road (again, someday buying a tri bike for racing in triathlons). Would I ever be able to really build a light, nice road wheelset with discs (and would I want to)?
