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.
Features:
- Hollow gear construction for optimized rigidity, lightweight and durability
- Durable teeth using a stainless steel construction supported by a carbon and alloy carrier body on 38t/36t/34t, alloy carrier body on 32t/30t
- HG 12-speed chain compatible
- Available in 30t/32t/34t/36t/38t
