Sram eTap
I went to a open house at the LBS and they had a number of vendors. The Sram dealer had a bike with eTap.. .very cool.
Still technically a "prototype" but what i saw was a production model.

i started a thread about this when it was first announced and there was actually a lot of good discussion, but it looks like it was somehow deleted

The lack of wires are not the point, its the "out of the box" design on shifting.
The left shifter shifts to a harder gear, the right to a easier gear and do both to change the chainring.
Also it's Sram Red and not Shimano... if you like Sram. If you don't then it doesn't matter.

Just asking a simple question.

Kit doesn't match
I read recently (Peloton mag.?) that if carbon frames don't need to be reinforced in areas where wires enter and exit, they can be built a fair bit lighter. Along those lines, not having to deal with wires makes building them easier too.
Neither are game-changers, but both are small improvements.

The other advantage over Di2 is that the batteries are interchangeable. so if your RD goes dead somehow then you can shift the front ring how you want then swap it to the back and have all 10-11 gears available for the way home. batteries are also much smaller and don't need a spot to mount them
anyone got a few grand to spare they can give me for when it comes out?

- It is not lighter because of the batteries. It's actually slightly heavier, even if you discount the cables.
- 1000 km isn't that much with one charge and probably you will charge it quite frequently.
- And while you won't need to change cables, you will have to replace the batteries after a couple of years.
- Riding and depending on an external battery system with rain, mud, hail involved? Well... I don't know. Time will tell how reliable it is.
- MSRP $2,758. That's in the same ballpark with a new mid-range carbon bike with Ultegra. It would be extremely hard for me to justify this spending instead of getting something really cool/useful. Or a nice winter training bike.
- It's a completely new technology for SRAM. Shimano has years of experience with electrical shifting. Also Campagnolo. Both of these manufacturers had some early stage problems with it. Sram tries to have it all. I hope they succeed, but I'd rather not be a tester of their product.

So far all vapor-ware. Want to see some early adopters give some feedback. Haven't seen any indication when it will actually be available.

I saw it at Interbike and was able to shift it a few times. Its pretty awesome. The shifting is quite fast and smooth. If you think about it...it's just four parts. Two shifters and two derailleurs. The rest of the drivetrain parts can be cobbled together. People are straight nitpicking on the charging. It's no different than charging your phone or any other electrical device. Its really not that difficult to pop the battery off and charge it before going to bed.
Going 1x will even be simpler. That will just be a shifter and rear derailleur.

Spare batteries are under $50 and weigh very little if you want to carry a spare. And they take about 5 seconds to change.

It's just speculation on my part, but I would think the proprietary wireless protocol SRAM developed is not without a roadmap of future product integration. Connectivity and analytics will be much more accessible… with the right devices, developed by SRAM, to translate the wireless protocol.
I love all the new developments, from a geek side, but I also love the mechanical simplicity of bicycles. I'll root for development and advancement, but still ride with cables.
