Hey y'all, I've been searching but maybe I'm just not using the correct terminology. I'm looking for 6 bolt disc brake rear mtb wheels (double wall rim, schrader valve, safe/reliable hub, rim brake compatible) without breaking the bank. Ill be using the 6 bolt mounting surface to locate AGK's sprocket. Tall order I know. I found these. http://bikeisland.com/cgi-bin/BKTK_STOR20.cgi?Action=Details&ProdID=603 Give me your thoughts, suggestions, input please on these or any other wheels fitting my requirements. Thanks
