Agree with the suggestion to test ride. However, make sure that you do the test rides with the same wheels. Wheels/tires can have a major effect on ride quality, and lots of people get fooled into thinking "it's the bike" when in fact "it's the wheels."cdecker78 said:I am wanting a Cannodale Synapse 5 but I am unsure weather it is worth the extra money for the Carbon version of this bike. Any input on this is appreciated.
