Shimano Dura Ace Di2 Battery SM-BTR1
Please contact email@example.com 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.
- Reliable and secure water resistant connectors
