Well, no doubt fit is key to comfort, but you could get the best fit in the world but if, as an extreme example, the bike happens to be a Time Trial bike, it's not going to feel so great on a longer endurance ride. An another example is the Specialize makes an endurance bike (Roubaix) and a race bike (Tarmac). I understand that bikes frames have different features based on the type of riding that will be done. Certain bikes are built to position the rider for the type of ride. Racing-position, down and aerodynamic, endurance more up right. I just cant nail down whether the Diva is a bike built for endurance. Thanks for the input!
