Salsa has a 2000 Specialized Hardrock XC Comp frame (small) that probably has no more than 60 miles on it; he won a Stumpjumper right after he got it, and raced the stumpjumper for a few years. The hardrock frame just hung around like some poor cousin... and now shows up periodically like a ghost from the "stored stuff" pile. I'm thinking that, under current usage, that frame will be fine 20 years from now!

PS - reasonable offers accepted! It's silver.
