For 12-speed, aluminum Durable & high performance The SRAM "X-Sync Road" chainring stands for maximum performance and durability in road and gravel use. Thanks to the special X-Sync technology, the teeth are much sharper than with conventional chainrings, so they grip the chain earlier. The rounded edges, in turn, ensure smooth chain guidance. Recesses ensure that dirt and mud are removed directly and do not clog the drivetrain. Suitable for 12-speed drivetrains.
