Which bike is the best overall value, the Giant Rapid for 1250 dollars, Trek 7.6fx, Trek 7.7fx, specialized sirrius limited, cannondale quick carbon 2, or the new trek 7.9fx. All these bikes caught my eye, but some our aluminum and some our carbon. Does the jump from aluminum to carbon make that much of a difference? Also, if I were to buy a hybrid bike with a carbon fiber fork would it break?
