Just bought a '95 Klein Quantum on Ebay, which came with Gipiemme (is that pronounced gip me? just wondering....) T Tre wheels. Broke my first spoke a week ago, and another one this morning. I'm 6'3", 250 lbs., and I haven't hit any major bumps, up off the saddle over RR tracks. First one broke at the threads, this one broke at the nipple. I see Performance has a Dura Ace/ Mavic set for $299, but that puts the price of my used bike up around new bike price. One LBS suggested that rebuilding the wheels might solve the problem--what do you guys think?
