The Zero Resistance is a model of tremolo bridge with a ball bearing pivot used in several Ibanez S series guitar models. It is more commonly referred to by its initials, ZR.
Other Ibanez bridges that borrow some design elements of the ZR include the SynchroniZR (ball-bearing pivot and thumbwheel spring adjuster) and the Edge Zero/ Edge Zero II
