Do you have shimano wheels, but need a Campagnolo cassette? I have a brand new Wheels Manufacturing Accelerator 11-23. This is a Shimano Ultegra cassette, broken down and re-pinned together with slimmer spacing to shift campy style. New. Free shipping in the US! $100. Retails for $140 http://www.excelsports.com/...major=1&minor=10
