Message: Call Shimano's warranty phone #1-800-423-2420. They are in my experience the most reasonable company in the business for warranty claims and will at least hear you out if the part is out of warranty period, which is three years for Dura-Ace. They will look at almost anything but you may have to have a dealer send it in. The phone # is a dealer #, you don't know where you got it, right? Seriously, for a company that could easily say "We're huge, we don't have to give a damn" Shimano is just plain awesome as far as handling warranty and at least taking a look at things.> My '96 (8 speed) solid core Dura Ace crank fractured after 3 1/2 years of fairly gentle use (no racing, but 28,000 miles). The fracture began on the inside edge of the right crank, and propogated to the outer edge. >Has anyone else seen this occur. If the solid crank can fracture after such a short time, how about the hollow core current model? I'm ready to upgrade components (but wanted to put the old D/A on my beater bike). I'm concerned whether the new D/A has sufficient long-term fatigue endurance. (Not sure I do either!)
