    Do you have matching race and pit wheels?

    I race a stock 2005 Cannondale Optimo CX (cantilevers/no disk) with the original Gipiemme wheelset. I am looking to purchase a set of pit wheels, which most likely be Mavic Open Pros on Ultegra Hubs. Basically, the Gipiemmes are good, solid race wheels, but hard to find a spare set, and the Open Pros are lighter, very strong, and affordable as right now I can only afford this one wheelset.

    The question is this:
    Do you have matching race and pit wheels, or two different kinds of wheelsets. And if they are different, how different and how do you get them both to work if you need a mid-race wheel swap? In my case, I plan to match the gearing, but the Gipiemmes are deep dish rims with a V shape and the Open Pros are low profile. Do you think I should set my brake pads up before the race to work on both wheelsets?

    Either that or get some inline barrel adjusters and figure out how many cranks on them it'll take to get the brakes back into ideal position.

    What do I know, though? I've got a spare tube, some levers and a pump waiting for me.

    No problems using different wheelsets for me. My rims are all close enough that there are no issues with the brakes. The difference I have is that I'm running both Campy and Shimano 9s hubs. there's a half turn difference on the rear der to go between them.

    My race and pit wheels are different. One set of rims is slightly wider, but the difference is not so drastic that it requires adjustment. Fortunately, the freehub body spacing in relation to the outer edge of the drive-side locknut matches up pretty well, so I can slap the spare in and go without worrying about RD adjustment. If yours don't match up, you can adjust the positioning of the outer edge of the freehub body in relation to the locknut on your spare wheels to match your race wheels; once this is done you won't have to worry about RD adjustment. You would do this by moving axle spacers from one side to the other; you may have to get some very thin spacers to get things to match up just right.
