Right now I'm sporting Mavic CPX 22 rims with Specialized hubs on a Tarmac Elite.
I'm thinking of upgrading to the standard Open Pro/Ultegra combo but will I notice any difference? Should I save my money until I can afford something nicer?
Also, I weigh around 150 in a hilly area, is a 28/36 setup the way to go? Some of the wheel builders online like BWW only sell a 32/32 config, while Colorado Cyclist lets you pick from 28-36.
