The Shimano CN-M9100 chain for XTR and Dura-Ace 12-speed has enlarged inner plates which create a perfect connection to the Dynamic Chain Engagement+ chainring. In this way, it contributes significantly to smooth shifting performance. Vibrations are avoided, chain hold is improved and pedalling efficiency is increased (HG technology). The SIL-TEC coating of the outer plates and rollers ensures smoother, low-wear running. CN-M9100 chains come with hollow-formed pins to save weight and are directional. As they are approved for e-bikes, there is also an extra-long version with 116 links. The matching SM-CN910-12 Quick-Link master link is included.
