The strongest system is a chain with no weak links. Eagle chain links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength.
And it’s also the biggest contributor to the ultra-smooth, precise, durable and quiet performance found in the 10-50 tooth cassette and X-SYNC 2 chainrings. Installation is made easy with a dedicated 12-speed Eagle quick link.
The SRAM HARD CHROME chain has a four times higher (wear) strength than other SRAM chains. This is due to the new machining process for the inner links and rollers. The push-pin strength and the overall strength correspond to the current SRAM chains. The HARD CHROME chain lasts longer and is extremely stable.
SRAM Chain Engineers have developed PowerLock as a tool-free, safe and constant way to connect their chains. Although PL does not require any special tools for assembly, each PowerLock can only be used once due to the narrow tolerance range of a 10 and 11-speed drive.
