Review on πŸ”Œ SHIMANO Ultegra Di2 Junction Box with Internal Routing by Isaac Ismail

Revainrating 4 out of 5

Part needed for Di2

There is not much to say about this junction box. This is a required part for installation. This makes it easy to tuck into the seat tube or down tube to hide. I added styrofoam insulation around the edges to keep the inside of the tubes quieter.

Pros
  • Recommended use: no mechanical cables
Cons
  • Almost everything is fine
