Designed to mimic the one piece design of the OEM pulley setup our Interlocking Rear Sprocket Spacer is one of the toughest around! Todays bikes are putting down more power and as a result are breaking rear sprocket bolts like they're going out of style! Keep your bolts in one piece and stop destroying wheels before it's too late.
** To allow universal compatability with all 2000+ style sprockets, locking pins are no longer preinstalled prior to shipment. Installation of the locking pins is quick and easy with any standard arbor press or hydraulic press **
