Pair 12-speed Wireless Di2 Shifters
Pairing 12-speed Di2 wireless shift levers can be done using the mobile app, wires, or using the SM-PCE02. This page describes how to pair via mobile phone, and E-Tube EW-SD300 wires.

First spotted at La Vuelta 2026, these are Shimano's upcoming 13-speed Di2 Hydraulic Disc shift levers.
This is what we know so far:
From the internal FCC images, it looks like you can press the thumb button both up and down, effectively turning it into two buttons.
This is just speculation on my part, but it would make sense for Shimano to only offer R9300 13-speed Dura-Ace as a rim brake only groupset.
It's their top tier groupset, and rim brake bikes are getting rare. And yeah.. I love rim brakes too, but the chances of us seeing a rim brake R9350 shift lever are slim
Compatibility with the current SW-RS801-S/E/T seems likely. Shimano introduced those a couple of years ago, and they work well. Including an SD300-type satellite shifter port makes sense.
Will the shifter have an SD300 port? Not sure... I'm going to say yes, but this could go either way.

Unpairing 12-speed Di2 wireless shift levers can be done using the mobile app or using the SM-PCE02 and E-Tube Project for Windows. This page describes both methods of unpairing wireless shifters.
