Shimano EW-WU111 Di2 Wireless Unit – ANT+ & Bluetooth With Electric Wire

Take your Di2 setup to the next level with the Shimano EW-WU111 wireless unit.

This little black box is the brains of the operation, allowing your Di2 system to communicate via ANT+ and Bluetooth.

That means you can connect to your cycling computer, your phone, and even do firmware updates wirelessly.

It's a brand new unit, still in its original packaging, and it comes from Japan, so you're getting that top-tier Shimano quality.

You'll also have the choice of either a 150mm or 200mm electric wire to integrate it seamlessly into your existing setup.

It's the key to unlocking all the smart features of your electronic shifting, like customizing shift modes and seeing your battery life right on your handlebar display.

If you're running Di2 and want to go wireless, this is the part you need.

It's sleek, black, and ready to modernize your ride.
