I cant use the stock hub because it has no mounting holes for a disk, and buying a new hub and spokes will be possibly more expensive then getting a new rim. Im still thinking about returning it. Bought anyways with the shop being an hour away to test it and see if it would even fit. With it being a all mountain rim it is wider and alittle bit more stronger. Plus like i said i wont be doing anything bigger then a 6 foot drop with this rim so if i do keep it. With my current skill set it should be fine. (it wont be used for downhill since there are none around me, it will be used for urban) Don't worry I feel the same concern for having a carbon rim. Im working out a plan.
