Theres no reason for SRAM to release a wired e groupset. Di2 is six years old and has it nailed. Unless SRAM can top this, there's not much point getting SRAM when UI2 is already almost as good as DA Di2, and probably cheaper than whatever SRAm is going to sell.

Pretty sure it will be wireless. Though Rotor groupset is interesting. From what J heard from the second largest Rotor distributor in Asia, it will take us by surprise. Electronic probably, wireless may be the technology is here, will e interesting for sure.

That 'dude' could be your DS in the team car :D A sudden and unexpected upshift means it's time to attack.

^ You touched the new Rotor groupset? SRAM is pretty clear going to be wireless.

Seems to confirm the wireless at ATOC.

I'm still a bit shocked at the new sequential shift arrangement. Sometimes I push a button on my Di2 to make sure that I'm in the correct front chainring. With the SRAM setup this wouldn't be possible. Plus one cannot shift both the front and rear mechs at the same time. Last but not least both hands are required to shift the FD. So if I have a bottle in one hand I could only shift the RD in one direction and none on the FD.

SRAM needs to design an EEG cap that goes on under your helmet that can pick up the electrical activity from your neurons/brain saying you want to shift gears. Have that broadcast by ANT+/BT 4.1 to the FD and RD. No need for shifters at that point. More aero and less weight. This is WW after all.

Um, as I said before. How is a mechanic supposed to work on the bike? How do you spin the crank if you need both hands to shift the gears?

Yes this would be a major challenge. On the positive side once an electronic group is dialed in it doesn't need to be worked on again :D

There is probably a mechanics mode or something similar.....the Bissell mechanics would have pointed that out if not.

I imagine they will add a front adjustment mode or something of the kind; for example you will hold down both levers for 5 seconds and then the drive side shifter will shift the front. Or you will double tap while in adjustment mode and it will shift the front. If they dont add something though I can see that being really annoying!

Or maybe a remote?
