Does anyone know what the offset of the rear wheel on a 07' NT is? I bought a Crossbones rear wheel with the intentions of just slapping a tube in it, bolting it on the bike and going for a cruse but the guy at the bike place told me it might not be that easy. So i searched the service manual and there is nothing for a cast wheel as far as offset. So someone who has a NT that replaced their wheels with aftermarket cast wheels might know. Please help.

Thanks
Justin
