Mavic Helium 700C clincher wheelset - $200, including shipping in the U.S. or Canada. This is the version with the CC9 freehub, which has a Shimano spline pattern but is wide enough to use with Campy 9/10-speed drivetrains (if you use the appropriate Mavic cassettes and spacers). I think it will work with a Shimano drivetrain also, if you have the right spacers. Excellent condition and light use. Can include tires and cassette if needed.
