I have a Hardrock Comp, and I put slicks on the supplied Alex rims. I still have the knobbies and I'd like to mount them on a cheap set of rims that are already built up. I do lite trail riding at most and few and far between at that, but I'd like to be able to swap out quick should I decide to do so. The Alex rims I have right now are Disc so I'd need a set of rims that are also disc. It's a shimano hub.
Thanks
