Flattop technology is so much more than a distinctive look. It allows our 12-speed chain to be lighter, stronger and more durable than anything that came before. The Apex chain uses the same construction as the Rival and Force chains, with a polished grey finish. This chain is designed for 12-speed Apex drivetrains and features Flattop technology for a narrower chain with quieter operation and increased strength and durability. It includes the Flattop PowerLock for secure connection and has a polished steel construction with a grey finish. The chain is compatible with 12s-Road systems and is available in 120 links or 114 links. It features a PowerLock D1 chain connector, polished inner and outer link finishes, solid pins, and chrome hardened pin treatment.
