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
• Durable teeth using a plated steel construction supported by a composite carrier body
• HG 12-speed chain compatible
• Available in 30T/32T/34T
