Each X-SYNC™ chain ring fits a single, universal spider—allowing you to change rings without removing the lightweight carbon crank arm.

SRAM X-SYNC™ 1X chain rings provide the highest level of performance and durability.
The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth.
The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain.
To provide the best possible performance in muddy conditions,
the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers.
Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1X™ drivetrain.
