North Shore Billet Variable Tooth Chainring Direct Mount SRAM Boost

Narrow wide direct mount chainrings for SRAM 11-speed and 12-speed Eagle cranks. The chainring is designed to give the optimum chainline in the middle of the cassette. This gives the smoothest shifting across the cassette and the straightest chain when in the largest or smallest cog. Chainrings are compatible with all Sram 9, 10, 11 and 12 speed drivetrains, and Shimano 9, 10, and 11 speed drivetrains

The tooth profile of our narrow/wide chainrings maintains excellent wear for a durable product.
