Shimano EW-WU111 In-Line Wireless Unit Di2 1 Color One Size

Fácilmente shimano podría introducir ésta tecnología en la centralita o en en junction box, pero prefiere ganar más al venderlo por separado. Por lo demás, me agrada ver el status en mi garmin.

The WU111 is very easy to install, simply connect one end somewhere inline with your Di2 system. It can either be installed as the last item in a chain or as a connector between two wires. Has worked flawlessly every time so far on two different systems. Note this is for 11sp Di2 as 12sp has wireless natively. The two systems are not interchangeable. It also requires the newer 11sp battery and will not work with the old battery. If you want to or need to update firmware, change settings or perform other maintenance on your 11sp system, this allows you to connect to eTube from your phone and replaces the annoying method of connecting a windows PC.

Came as advertised and works great.

Not sure why this didn’t come with the bike in the first place, but hey…. Shimano gonna Shimano. Really easy to instal on my bike, since there was a “pass through” adapter that could just be replaced with this unit. Works great.

The wireless plug for my di2 system has changed how I use my bike, and it is the best upgrade I've done next to the electronic shifting. The ability to log into an app and adjust the gearing on the fly is amazing.
