Flattop technology is much more than an eye-catching look. It allows our 12-speed chain to be lighter, stronger, and more durable than any previous chain. The Apex chain has the same structure as the Rival and Force chains, but with a glossy gray finish.

PowerLock®
SRAM chain engineers developed PowerLock® as the safe and consistent way to connect SRAM chains without the use of tools. Although PowerLock® does not require special tools for installation, given the tight tolerance range of a 10, 11, and 12-speed chain, each PowerLock® should be used only once.
