DetailsThe Shimano Di2 PC diagnostics tool. This product, when connected to the 'E-Tube Project' software (downloadable) can run a multitude of diagnostics on your Di2 groupset (Ultegra or Dura-Ace). For example:
• If you're having any technical issues, this will tell you the origin of the issue within the groupset.
• You can reprogram the right STI lever to shift faster, or slower.
• You can reprogram the right STI lever to do one shift per push, or three, or non-stop shifting (until you lift your finger off).
• If you want to the right STI lever to shift the front derailleur (instead of the rear), or vice versa, you can also reprogram that.
