Show Description

The SuperProX series is a performance option for those looking for prime shifting capabilities, designed for use with the Shimano® XTR M960 Crankset. This is a ramped ring with modified shifter gates and special profiles to allow hassle-free shifting.

  • CNC cut from 7075-T6 aluminum.
  • Middle and outer rings are cut from a thicker 0.190 material to prevent the chain from falling between the granny and middle ring.
  • Middle and outer rings have stainless steel shifting pins to enhance shifting.
  • Works best on a 9-speed drivetrain.
  • For use with the Shimano XTR FC M960 Crankset.
  • These chainrings will not work if mixed with other brand rings; for best performance, use only with other SuperProX rings as a set.
