Yes you can. ABS usesspecial bearings, so I am assuming that they are either providing the wheels with new ABS bearings or re-using your current ones. Hog Pro is all over it already: http://www.hogpro.com/showpage.php?page=gallery2.htm

 

Well, I just ordered my 21 X 18 combo today through Hogpro. I talked to a guy named Phil. This guy was not only nice, but he answered all my questions and was very happy to do so. I recommend that you call Hogpro first, great customer service.

Anyways, I got the Aspen wheels from Renegade. I think, not only will they look bad to the bone on my RK, but I will love that bike even more. Also up here in northern Cali, I only know of one guy that has the 21 X 18 setup, so I'm going to turn a lot of heads. They get shipped to my house on Thursday and I drop them off with the RK on Saturday. I'm so excited I feel like a little kid on Christmas day

In the Bay Area, Ca, you either have 21/18s or are about to get them.
