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 ...

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 This drop handlebar cable set is required to connect the shifters to the included battery indicator junction box controller Ultegra Di 2 also requires EW-SD50 cables from the battery indicator junction box to the rear mech front mech battery & the bottom bracket junction Di 2 cables cannot be cut to fit Reliable & secure water resistant connectors Not Flightdeck compatible ...

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 ...

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 This junction A is required to connect the shifters via E-tube wires to the down tube junction wire 5-port design one for down tube wire to bottom bracket junction four for shifter connection. Ideally suited for TT/triathlon with multiple shifter positions Battery level indicator feature E-tube EW-SD50 wires not included Additional charging point when using internal battery Gear index setup switch to allow fine tuning via shifter buttons Reliable & secure water resistant connectors Stem mounting strap included ...

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 Ultegra Di 2 uses a fully removable individual cable system from the battery indicator junction box enabling fine tuning with the correct cable length to each component for easy & tidy fitment This kit contains SM-JC40 bottom bracket junction SM-BMR1 long external type bottle cage battery mount EW-SD50 individual wires: 1X 1000 mm 1X 500 mm 2X 300 mm & SM-EWC2 black stick on wire covers: 3X 300 mm 3X 50 mm Ultegra Di 2 also requires a handlebar cable set to connect the shifters to a battery indicator junction box &40;comes with handlebar cable&41; External cable sets are ideal for upgrading your current bike to Ultegra Di 2 if it does not feature the internal cable routing option EW-SD50 individual wires are available in varying lengths there is no need &40;or facility&41; to cut these cables Reliable & secure water resistant connectors ...
