Yeah georgia ive seen the breaks in person myself. Ive not been impressed with some of ITP wheels as far as strength goes. I trashed a new 650 prarie few years back due to em, The wheel bead ring just flew off. Some of the older designs were not much if you like to ride hard.
By the way what backspacing are you running on those rockstars?
