Dynamic Chain Engagement (DCE) is used to hold the chain and help prevent chain jump out. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge and alternate profiled tooth shaping. This provides superior chain retention, lower driving sound, increased durability and drag to a minimum
Hollow gear construction for optimized rigidity, lightweight and durability
Durable teeth using a plated steel construction supported by a carbon composite (CFRP) carrier body
