Don't let Warp 9's prices fool you, they only use the highest grade stainless steels and aluminum available. As riders, they have witnessed the current trend of off-road wheels - they are priced too high for the working class guy and most do not come complete, adding additional cost and frustration to the purchase experience. As riders, they decided to do something about it, and Warp 9 was born. Anodized 7000 series aluminum rim. Stainless steel spokes and nipples. Aluminum hub. Stainless steel brake rotor included. NAK seals. O.E.M. bearings. Zinc-plated nyloc hardware.
