Has anyone see the vid to this? No big battery packs and no cables or wires. Loving it! (Cant afford it though) lol

Wireless is clearly the next stage of evolution of e-gears
I am surprised by the claimed battery life - A CR2032 isn't that powerful and I wonder if that is optmistic?
"Shifters use CR2032 coin cell batteries with about 2 years of life"
Sounds plausible to me. They're only transmitting signals, and only then when you change gear.I am surprised by the claimed battery life - A CR2032 isn't that powerful and I wonder if that is optmistic?

Think of your cadence and speed sensors. They most likely use CR2032 batteries and they're transmitting all the time you're riding. Their batteries last a good while.
Surprised it actually looks decent. Wasn't sold on the wireless idea before, and to a degree still not, but it seem to make sense as long as there a no issues with it losing signal, ever.
Providing no warranty issues, could be a genuine alternative to Di2 in a year or so when the price comes down.

true enough, it is only in the derailleurs where a bit of oomph is needed to actually do any workThink of your cadence and speed sensors. They most likely use CR2032 batteries and they're transmitting all the time you're riding. Their batteries last a good while.
That's right. The mechs have (relatively) big Li-ion batteries that you can unclip to recharge.
A nice touch is that those are interchangeable, so if you keep forgetting to recharge after a succession of rides and the rear goes flat out on the road (and the chances are it'd be the rear since that's the one you do the lion's share of your shifting with) you just can swap the battery packs around to retain use of your cassette and forgo changing chain rings instead.
