Interested in getting a CAAD8 R1000 but have been reading some scary things about how long I can expect the frame to last (1-2 years of hard riding/racing, 3 years of moderate riding/racing). I am admittedly not that knowledgable about alum. frames, do all of them only last 2-3 years? The other scary part about it is that I have been reading that C'Dale does not warranty "natural fatigue" of the frame. So, I'm 190 lbs and plan on doing training rides and some road races, can I get more than 2 years out of a CAAD8/R1000? Thanks, TBone
