The Eagle™ series stand for smooth, quiet, efficient and durable drivetrain systems. So that the chainrings are in no way inferior to the other components, the SRAM engineers have performance and wear behavior of thousands of X-SYNC™ chainrings put to the test. The direct result is the longer, curved tooth shape of the X-SYNC™ 2 chainrings which improves not only the power transmission, but also the durability.
The chainring made of steel and with 104 mm bolt circle diameter (BCD) is perfectly matched to the current Eagle™ chains.
X-SYNC™ 2 | The consistent further development of the proven SRAM X-SYNC™ technology increases with its special tooth profile the chain tension and efficiency when pedaling. However, X-SYNC™ 2 not only improves the chain guide, but also increases the longevity of the chainrings with less friction, noise and wear at the same time.
