Ok so the rims on my ride are prett much square, more of a hexagon actualy, or maybe an octagon...ok, shapes not really all that important, truth of the matter is i need new rims, i ride a Hard tail XC bike, w/ rim breaks, i need a wheelset that'll hold up to a little abuse, and the rocks in Arizona.... however... (there is always a however) money IS an issue, a rather big issue at that... anyways, any advice would be greatly appreciated, thanks for your time!!
