The Apex chain uses the same construction as the Rival and Force chains, with a polished grey finish. FEATURES 12-speed. Flattop technology allows for a narrower chain with quieter operation and increased strength and durability. Includes Flattop PowerLock. Polished steel with grey finish.

The unique link shape of Flattop technology not only allowed for a wider gear range, but also results in quieter drivetrain operation and increased chai
