Shimano Di2 Junction A EW-RS910 Internal

The new ShimanoEW-RS910 Bar-End or Frame Mounted Internal A Junction/Charging Port is part of the Dura-Ace 9050 Di2 release. This new A-Junction has finally given a cleaner option for Di2 bike cockpits by removing the A-junction from beneath the stem and moving it inside the handlebar end or inside the frame on bikes with a compatible mounting point in their frame like the compatible versions of the Trek Madone and Pinarello Dogma.
