Shimano Dura-Ace Junction-A Box, 5 Port for Road Handlebars

Not Enough Available
£109.99

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: Stem mounting strap not included.
