Built with the needs of E-MTB riders in mind, and incorporating the same X-SYNC chain management technology found in every SRAM 1x drivetrain, EX1 offers 14-, 16- and 18-tooth sprockets for Bosch motors.

 

SRAM X-SYNC 1x chain rings provide the highest level of performance and durability. The 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.
