Great Di2 main junction unit
Shimano products are the best components. This junction unit is no exception. Excellent performance and always reliable.

Great price and speedy delivery. Awesome all the way around

Necessary part for Di2 install
It’s a necessary part, especially if you don’t have a handlebar that allows the end junction box. It is easy to install, and works well to charge the system and program/adjust the shifting. I did not like the adjustable strap to mount it, and instead purchased the K-Edge mount to install it directly below the stem. ... show more

Never buy from these idiots!
Product is fine, the retailer was appalling!

Nessecary but with minor gripes
This is the newer junction box for the di2 system. It allows you to connect the USB charger/firmware upgrader to the systems without using the bullet style plugs. The Good; It does exactly what it is supposed to. A good mounting kit is included The Bad; It's a tad pricy for merely adding a USB connection port. The older junction boxes did more or less the same thing are have now dropped significantly in price. I would buy it again if I were doing another build, I would still object a little. ... show more
