I got a 56cm caad10 and im 6 ft 1. I feel fine on my bike as its my first serious one but when I see myself on it it looks really small on me. The bike handles great but im wondering if im not utilizing my max potential because of some fit problem I dont know of. I dont feel like spending alot of money on a pro fit so im coming here. After some intense rides my right shoulder hurts and my back begins to hurt. Heres 2 pics of me riding on the hoods. I feel I should lower the seat and extended the stem.
