I recently converted my new Chris King R45 form campagnolo (as originally built) to shimano and I am selling the freehub body and conversion kit with bearings. This is all you need to convert your Shimano/Sram Chris King R45 to campagnolo. The parts have limited miles. New, this conversion kit cost $425 (http://www.wheelbuilder.com/chris-king-r45-shimano-to-campagnolo-conversion-kit.html). I will also include a Chris King 11sp campy lock ring (pictured on the cassette, I'd sell the cassette too if you want it).
