Technology
Dynamic Chain Engagement+
Shimano’s Dynamic Chain Engagement+ is a special gear teeth profile designed for use in single-chainring configurations for XC, enduro, and trail riding.
It gives more chain retention and smoother pedaling - even over bumpy terrain. Chain retention of any gear will reduce abrasion and worn out.
Features
- 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
- HG 12-speed chain compatible
- Available in 28T/30T/32T/34T/36T
