The new SW-RS801-T tops shifter was introduced when Shimano released Ultegra R8100 / R9200 to the world. It lets you shift your 12-speed bike from the tops, much like the older satellite shifters did.
These connect to the special Satellite Shifter port found on the 12-speed shift levers. This will be either the 2nd or 3rd port from the top (basically, the bottom port is always the satellite shifter port). They will not work in any regular SD300 port.

While previous satellite shifters were one unit, these newer ones consist of a shifting unit and a clamp, or band. In theory, you could actually stick the unit onto your handlebar using some strong double-sided tape,
Alternatively, slide the unit onto the band and then use the provided double-sided tape to attach it to the handlebar. You then use a tie-wrap to more permanently secure it to the handlebar.
These are sold as a pair, weigh 5.7g each and come with a 260mm wire.
Satellite shifters will not work with 105 Di2 shift levers, since those do not have any extension ports.
Shimano 12-speed satellite shifters are tiny buttons or shifters that you can place in the drops, on the tops, or on your aero extensions. This page explains how to install the different satellite shifters and how to wrap the handlebar tape around them.
Extending 12-speed Di2 satellite shifters is relatively easy. I'll use an EW-JC302 junction, an EW-SD300 wire, and a knife to extend a couple of satellite shifters.
The FCC just released the manual for the new Shimano RD-R9250 12 speed semi-wireless rear derailleur. Let's have a look and see what we can find!
