11 more years, how do you know? Is this based on the type of aluminum? I read that 6061-T8 is used for baseball bats and that T6 is just a hair shy of T8 (has something to do with lithium). In other words does the 6061-T6 last longer than most aluminum frames?

My friend's bike failed catastrophically after just 8; although I do not know what type of aluminum was being used.

The folks at GT said that I should hang my frame up and get a new one, but this could be just marketing.

I did just order a steel frame (Voodoo), which will be a sweet sweet ride, but when I want to kick ass, I prefer the GT Zaskar (perfect geometry and engineering).
