Aluminum chainring for road bike cranksets with SRAM 8-bolt Direct Mount standard. Suitable for 1x12-speed drivetrain systems. Equipped with X-SYNC technology for a more direct power transmission and higher resistance.
X-SYNC™ | Chainrings with X-SYNC™ technology are an integral part of SRAM 1-speed shifting systems. The sophisticated tooth design with high, square edges ensures maximum performance and durability. Not only the narrow, sharp tooth profile grips the chain earlier than teeth with the traditional triangular shape, also the rounded chamfer edges support the chain's guidance. In addition, to withstand adverse conditions, X-SYNC™ chainrings are provided with mud-repellent recesses, which protect the links and rollers of the chain from dirt.
