The Race Face folks have brought their Turbine technology to these S series rings, specifically designed to work interchangeably with your Shimano® cranks. They're three times stiffer than previous Team chainrings (yet no heavier overall). That makes for much sharper, quicker, and more responsive shifts, as well as increased impact resistance.
- Asymmetrical tooth profile and more upshift and downshift zones yield instantaneous smooth and quiet shifting, even under load
- For use with 2008 and later Shimano XTR, XT and SLX cranks
- Four-bolt 104/64mm BCD
- Rings are 22, 32, and 44T
