Shimano Dura Ace Di2 Battery SM-BTR1

Please contact skypartner@rapha.cc to place your order.

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.

E-tube Di2 uses a fully removable individual cable system from the battery indicator junction box enabling fine tuning with the correct cable length to each component for easy and tidy fitment.

EW-SD50 individual wires are available in varying lengths, there is no need (or facility) to cut these cables.
