Ohhh that is an interesting idea! Would absolutely love to see something kind of like Qalvin for Quarq for adjustment and trouble shooting! A wireless link with a wahoo ANT+ key or BT4.0 to do all the same things that Shimanos E-tube program does.

I was very hesitant on ordering any Electronic Groupsets....that and my current frame doesnt allow it. But now, Im very interested in this. That. And I get to keep my current red crankset and Cassette as well.....I get to keep some parts. But this looks very promising.

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.

This has already been done years ago by Parlee and the Toyota Prius group with sensors in the helmet and Di2. Seemed to work fine too. I'm just perplexed that nothing has evolved out of that since then... Seemed to be made pretty much out of stock electronics and far from complicated.

it's all on YouTube...

Are we going to have all those same talking heads make a new video telling us how great wireless SRAM is and how connected you now feel to your bike? Sheesh. :roll:

If this is wireless, I think they should make their groupset 10 and 11 speed compatible. Don't think that should be too hard since they're cramming all the processing into each part. This would really make a lot of people very happy!

A config option for 10 or 11 speed would be great!

I understand that the shifters work like this (so not double tap):

Right Shift - Up the rear block
Left Shift - Down the rear block
Both together - Front Shift (either way from where you are)

Seems different rather than better, and how do you dump gears front and back at once?

With electronic shifting I could see 12 or 13 speeds on the horizon :mrgreen:


Agree that electronic would be the way to go for the necessary precision but I think there will be several factors holding back manufacturers from going in this direction. It would require an even narrower and more expensive chain with follow-on impacts all through the drivetrain: derailleur, chainsets, cassettes all would need redesign. For any manufacturer with existing groups, almost nothing in any existing drivetrain would transfer across to a higher number of gears, unlike the current situation where mechanical and electronic systems share several components.

Still, an interesting idea.

It might be ok since 99% of PMs are already wireless and I don't hear a movement going away from that.


Big difference between missing data from a PM and not being able to shift when you want to.


PMs have tons of data drop problems still.

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


Not true. My Ultegra di2 still needed maintenance albeit not as much as a cabled group. Usually it would have to do with rear trim as the drivetrain wore.
