I have a 2002 titanium Lemond frame. Just found a crack on down tube. Bummed to not be able to ride it anymore. Is it worth trying to repair (if it's even possible)?
Getting it fixed may cost more than the frame is worth and there's no guarantee it won't crack again. My husband's titanium Litespeed road frame cracked on the head tube twice. The first time, Litespeed replaced the frame. The second time (cracked in almost the same spot as the first one) Litespeed said the frame had exceeded the "lifetime" of the lifetime warranty. He took it to a couple of welders but they said it would be $600 - $900 to fix (weld on a new head tube).
He gave the Litespeed frame to a welding student for parts/pratice and replaced it with a cheaper aluminum frame. Since he's not racing, he's not worried about a few extra ounces of weight in the frame and if it breaks he's only out a couple hundred dollars instead of a couple thousand.
