Our new Direct Mount Chainrings for SRAM 8-Bolt Mountain Cranks are optimized for the new SRAM Transmission mountain groupsets and T-Type chains. These are for folks who have the latest SRAM T-Type Transmission groupset that want a different chainring size beyond stock offering or upgrade to a Made In USA option with an optimized tooth profile for better performance.
