Pretty much any of the 5 spoke wheels are what you want. I am told the the only difference is in the diameter of the rotors. You use all the R1 parts (rims, bearings, spacers, sprocket carrier, sprocket), except you use a special axle you get from a guy on Psychobike called Chopaleg. You use the stock rear axle, and somewhere I posted how much you have to space the calipers, F&R, but I do not recall off the top of my head.
FWIW, I bought my 08 wheels, tires, bearings, rotors, sprocket and carrier off the R1 forum for $500 shipped! Had like new Michelin Power Pures on them, too!
