SRAM X-SYNC™ 1X chainrings offer the highest level of performance and durability. The large square serrated edges of SRAM X-SYNC™ engage the chain sooner than conventional triangular teeth. The sharp, narrow profile of the teeth, along with rounded chamfered edges, help manage a slack chain. To ensure the best possible performance in mud, X-SYNC™ chainrings have been equipped with mud evacuation cavities for the chain's rollers and inner links. Designed in Germany, the X-SYNC™ chainrings are an integral part of the SRAM 1X™ drivetrain.
