After two years of engineering work and rigorous testing, the all new Turbine chain rings are ready to ride! Completely redesigned from the ground up, these rings shift like nothing else. As with the previous Team and Race rings, the new Turbine rings are made in Canada from 7075 aluminum, so they are built to last. Offering unparalleled form and function, these rings are second to none, and come standard on Race Face Deus and Next cranks.
