Shimano Junction Box A

R 1,650.00 

This junction A is required to connect the shifters via E-tube wires to the down tube junction wire.

 

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.
