I just bought a Cannondale Black Lightning (1989, I think) and it seemed like a deal at the time - $100 and it's in great condition, but I'm starting to wonder what I've gotten myself into. The wheels are Mavic GP-4 (tubular rims) with Suntour Cyclone sealed bearing hubs and the tires are not installed. I've talked to my local bike mechanic and he was telling me the agony and frustration of installing tubular tires. So now I'm wondering if I should switch out the wheels or just give the tubulars a go. Any thoughts?
