- Dynamic Chain Engagement: This technology effectively holds the chain and prevents chain drop. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge. This all aids drivetrain performance on uneven terrain, keeps chain noise low, drag to a minimum and increases chain and chainring durability.
