Wireless gear shifters? What was wrong with a cable? Even if you don't want it to be a mechanical connection, you could still at least send data over that instead of wirelessly...

It's much easier to maintain, as headsets have become integrated it's become harder and harder to work with anything that runs from the brake levers through the frame.

Shifting is faster and more precise, with no need for readjustments. It also eliminates a lot of cabling, which makes it look cleaner and simplifies the setup.

Not needing to route cables (or wires) along and/or through the bike frame is a huge improvement. Anecdotally, everyone I know that has adopted Di2 seems to love it. The cost of these systems is negligible for the type of buyer who is shopping for high-end groupsets.

Besides what other have answered you already have a lot of wireless connections on a race bike. To the sensors measuring speed, cadence, watts, and possibly stuff like rear traffic radar, gear selection etc..

It all integrates with an unwired bike computer, so wireless shifters makes fine sense in the system.

Hahaha -- can't wait until someone figures out how to hack SRAM's wireless seatpost dropper[1]. 1. https://www.sram.com/en/rockshox/models/sp-rvb-axs-a2

start packing a flipper zero and make friends up shift on steep climbs

There is electronic shifting over cable too.

Electronic shifting in general is far better than cable both in terms of performance and maintenance.
