Bought a 2016 Cannondale Quick Speed 1. Love the bike but I am not sure if the seat is in the right position. I am only 5' 8" tall, but I am all upper torso. My pants length is between 29 and 30. I think I have the seat at the right height but when I am seated, I feel like my head might be too far at or past the handle bar. Where should a riders head be in relationship to the handlebar when riding a hybrid bike?
