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. Leveraging the Turbine technology RaceFace has designed the Turbine S rings to work interchangeably with your Shimano rings on your Shimano cranks. Swap any Turbine S ring in place of your existing Shimano ring or for unparallel performance replace them as a complete set. As with the previous Team and Race rings, the Turbine rings are made in Canada from 7075 aluminum, so they are built to last.
* New asymmetrical tooth profiling and more upshift and downshift zones yield instantaneous smooth and quiet shifting, even under load.
* Three times stiffer than RaceFace's previous Team chainrings without any weight gain. Net result is much sharper, quicker and more responsive shifts as well as increased resistance to impacts.
* Machined in Canada with US made aluminum
