RaceFace 9 Speed Turbine Chainring Set Shimano
You may not be aware but not all rings are created equal. Each manufacturer utilizes slightly different orientations and spacing between their rings and even sometimes between crank models. Therefore direct compatibility has not existed until now. The Turbine S rings work interchangeably with your Shimano rings on your Shimano cranks. Swap any Turbine S ring in place of your existing Shimano ring or for unparalleled performance, replace them as a complete set. The Turbine rings are made in Canada from 7075 aluminum, so they are built to last.
