Perfect Chain Engagement It features Dynamic Chain Engagement technology, which uses a unique tooth profile that provides superior chain retention, drivetrain smoothness and less chain noise. This updated version of the XTR chainring includes a narrow-wide tooth profile for even better chain engagement and makes it the perfect chainring to suit any rider, in any condition. Technologies: 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.
