PRODUCT REF: SMEW90A
Upgrading to one of Shimano's fantastic electronic groupsets, such as Dura Ace 9070 and Ultegra 6870, is a fantastic choice and to do so you will require this Shimano SM-EW90-A Dura-Ace Di2 9070 STI Handlebar Junction Box.
This Junction box is used to connect the shifters via E-tube wires to the downtube junction wire. To accomplis this, a 5-port design is used with one for the downtube wire to bottom bracket junction and four for shifter connection.
Shimano have made getting used to your new electronic gear shifting easier by incorporating a battery level indicator feature. Additionally, this junction box provides an alternative charing locations for internal batteries.
As a final flourish, you can use this SM-EW90-A junction box for the gear index setup switch to allow fine tuning via shifter buttons.
Please note: This junction box DOES come with a stem mounting strap, but NO E-tube EW-SD50 wires are included, but these are available separately.
