I am about to buy a Roubaix and I am trying to decide between the Elite and the Comp. The only difference between the 2 is the Elite has the SRAM Apex and the Comp has 105's. According to the store guy the 105's shift faster and smoother, but to me the SRAM felt faster and smoother, while the 105 brakes were much more responsive. I am very torn and just looking for other experiences/opinions.
