I'm sure this has been covered once or twice but has there been a definitive answer? Will I crack a carbon frame from regular, non-racing use? I'm 220 lb, 5'8" of chub and muscle...mostly the former. I was looking at a carbon bike but the sales guy says I might conisder sticking to aluminum or going titanium because carbons can crack under load. I didn't know if I was being insulted for being heavy or conned for having been naive about frame materials. I'm looking to fellow clydes for their experience.
What say you about carbon? Is one manufacturer's carbon better than the rest? Would you buy a used carbon bike from a fellow clyde? TIA.
