Ring had to be purchased from another vendor, they only had a 10% over drive. If you want something more it's private label and limited availability. If your after more look into innovators west/ metco balancer,ring combo instead. The rings are changed easily and can be had from several vendors for your desired pulley combo. Install was easy and the directions were well explained as per is concerned. Would recommend the LSA race drive to anyone.
