Notre avis

The latest innovation from Shimano for wireless mounting.

Denis M.

A former racer with a keen eye for equipment

The new integrated connection box Shimano Di2 EW-RS910 has been designed to offer a neater and more discreet integration. It is compatible with all 31.8cm handlebars (it is fitted in place of the right-hand handlebar cap).

For assembly, it must be coupled with a Shimano Di2 EW-JC130 Y-cable to connect the two grips.

This little box is the brain of the Shimano Di2 groupsets. As well as sending shift commands, the EW-RS910 is used to charge the battery and update the system. It is compatible with Ultegra 6870, Dura Ace 9070 and Dura Ace 9150 drivetrains.

- Reference Shimano IEWRS910
- 2-port connection
- Compatible with all 31.8cm
hangers - Compatible with specific internal Di2 frames
- Charge level indicator
- Rechargeable via Shimano SM-BCR2 charger

I had the connection under the stem and now at the end of the handlebars, I prefer it. (Translated review)

Connection box mounted at the end of the handlebar, it's impeccable, it frees the stem. (Translated review)

I bought this housing to complete the integration of my bike with a combo/bar where (right side end) the Di2 housing fits. It is easy to install, does not interfere with changing or installing the handlebar tape, and is very discreet compared to my old housing which was under the stem. (Translated review)
