Great piece of technology!
I love this junction box because it eliminated all the messy wires outside of by bike. Now it's all cleaned up and I can charge my battery right from my handlebar end without the ugliness!

Super convenient and worth the wiring hassle
Once you figure out how you're going to run your wires this gem makes your installation very clean. No need to hang that rectangular Junction A under your bars.

Direct Replacement
I broke the charging port and needed to replace it. Shimano brand = shimano pricing but it was easy to install and worked perfectly.

Good but......
Way cleaner than the old junction box. However, I did have to drill a hole in my handlebar.

Centralita para Shimano Di2
Esta centralita la he comprado para sustituir la anterior que tenía bajo la potencia. Esta nueva versión no hace nada distinto de la otra, salvo que por tamaño, da la posibilidad de ponerla en el tubo del manillar, o como en el caso mío en el tubo inferior del cuadro Pinarello F10 que viene con un alojamiento especial para ponerlo.
