The SRAM Eagle X-SYNC chainring for BOSCH drives made of steel is the SRAM answer to the large forces that are transmitted by modern e-bike motors to the drive. A steel chainring is naturally subject to less wear due to its robustness and simply lasts longer. X-SYNC is a Narrow Wide tooth profile, which guarantees maximum performance and durability. The long tooth edges grip the chain earlier than traditional teeth. The sharp and narrow tooth profile and the rounded edges support the chain guide. Furthermore, depressions effectively ensure the removal of dirt and mud in the chain plates and rollers. The focus is on durability. Thus, the new tooth profile reduces friction in the drive and improves self-cleaning. For more pleasant and efficient pedaling with better chain guidance and higher chain tension provides an even more aggressive tooth shape. In addition, the noise was minimized. This chainring is specifically designed for use with Eagle chains and groups and compatible with 11- and 12-speed drives.
