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. This all aids holding the chain firmly on uneven terrain while keeping chain noise and drag to a minimum and increases durability

Key Features:
  • Hollow gear construction for optimized rigidity, lightweight and durability
  • Durable teeth using a plated steel construction supported by a carbon composite (CFRP) carrier body
  • Dyna-Sys11 HG-X11 11-speed chain compatible
  • Available in 30T/32T/34T
