Shimano Dura-Ace Di2 5 Port TT Handlebar Junction Box
The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching but provides effortless gear shifts. The Shimano Dura-Ace Di2 5 Port TT Handlebar Junction Box connects the shifters via E-tube wires to the down tube junction wire. This is a five-port design with a battery level indicator feature so you know when your system needs charging up.
Please note, the stem mounting strap is not included.
