I obtained a nice set of Shimano Ultegra 8 speed brifters for a great price. So now I'd like to upgrade my Cannondale SR500 that currently has RSX 7 speed. In order to make this change, I would like to upgrade the wheel set rather than change the freehub and re-dish the current rear wheel for the 8-speed cassette. I'm currently riding on Mavic CXP10's with Shimano RSX hubs. I'm considering two wheelsets. New or lightly used Easton Vista's and/or a lightly used set of Mavic CXP33's. One question I have is, I'm assuming this will be an upgrade and I will see a performance improvement. Is this correct or are those old CXP10's good rims, and the upgrade is not worth it. One other comment, the CXP10's are in great shape, true and I'm having zero problems with them. I don't know how many miles are on them because I purchased the bike used, but when I repacked the bearings, there was little to no signs of wear.
I will not discard them, instead they will be transferred to my Bianchi Campione that has a low end set of Mavic's.
So should I make the change? Your thought are welcome.
