I'm hoping the new wheels match up close enough to my tubulars that I won't have to adjust the pad holder position, especially now that I use just a smidgeon of toe-in with the carbon tubulars so they don't groan and are less grabby. I stick a doubled up business card under the front of the pad as I set it. We'll see how they match tonight when I swap them. If they do match up pads-wise, I'm sure Karma will dictate that my RD indexing be wildly different. There is a reason a lot of folks stick to one set for both training and racing.
