##Shimano EW-SD50 E-tube Di2 electric wire, 250mm 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 EW-SD50 E-tube Di2 electric wire, 250mm connects the junction (either SM-JC40 external or SM-JC41 internal) to the rear mech, front mech, battery and to the handlebar battery indicator junction box. The water resistant connectors are reliable and secure and come in variable lengths as it is not possible to cut them to fit.
