The SRAM Apex chain has the same construction as the Rival and Force chains, but with a polished grey coating. Flattop technology makes the chain lighter, stronger and more durable than previous SRAM 12-speed chains.
PowerLock – SRAM chain engineers developed PowerLock as a reliable and consistent way to connect chains without tools. Although PowerLock does not require special tools for installation, the particularly strict requirements of 10- and 11-speed systems mean that it can be used only once.
Flattop – a narrower chain was developed to enable the use of X-Range technology. The unique Flattop chain shape allows a wider gear range while providing quieter operation and increased chain strength and durability.
X-Range – this technology is designed for modern road cycling. The drivetrain was redesigned to provide a wider range, more useful and smoother gear progression, and smarter shifting settings enabled by the AXS system.
