The SRAM X-Sync 2 chainring has been specially designed for the Bosch E-Bike in collaboration with the SRAM Eagle 12-speed drivetrains. This chainring transmits the high torque of the engine without chain drops. The teeth have SRAM's proven X-Sync 2 tooth profile. This has alternating narrow and wide teeth grip to perfectly keep it in the rough terrain. The cutouts at the base of the teeth have been specially engineered to counteract sludging of the chain and chainring in difficult conditions.
