Dynamic Chain Engagement (DCE) is used to hold the chain & help prevent chain jump out. This is achieved by using a broader & taller tooth profile in conjunction with a special hooked leading edge & alternate profiled tooth shaping. This provides superior chain retention lower driving sound increased durability & drag to a minimum. Durable teeth using a plated steel construction supported by a composite carrier body Dyna-Sys 11 HG-X11 11-speed chain compatible Available in 30T/32T/34T ...

To ensure that the signal goes from the shifter to the derailleurs the reliability of the electric cable has been proven by repeated field tests in various riding conditions including extreme temperatures rain mud & cobble stone roads The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates corrosion & stretching but provides effortless gear shifts Dura-Ace Di 2 requires 2 cables: a handlebar cable set to connect the shifters to a battery indicator junction box or Flight Deck & the other to connect the handlebar cable to the battery & derailleurs. This battery to derailleur cable is available for internal or external routing in different lengths allowing for various frame sizes The handlebar cable set is available in two types: one for use without a Flight Deck computer instead using a simple junction box to display battery life; the other is for use with Flight Deck which can providing information like cadence gear position battery indicator & more Handlebar cables should not be cut to size or modified in any way Reliable & secure water resistant connectors ...
