I am new to street riding, used to do mountain riding when was younger and more in shape. I just bought a cannondale synapse and love it, but am concerned that they sold me one with a frame too small. I am 6`2" and they sold me a 56cm frame. They fitted me for the bike by: raising my seat 5 inches and put ext bar on handle bars (specialized brand, length unknown approx 5inches). Any thoughts
