There’s at least one person over on weight weenies that has dumped di2 firmware IIRC
Etap uses a proprietary protocol (airea?), no idea if anyone has attempted to decrypt that

I believe it was @motorbacon that figured out the original Sram blips/clics and Di2 sprint shifters are just dumb switches and connectors can be cut and swapped.
Why are we trying to do this again?

I think that everyone with a slightly unhealthy interest in electronics knows that mod. But it’s not CANbus or firmware hacking, which are both well outside most every bike geek’s wheelhouse.

you know how people liked making Shimergo groups? or how people like putting Ratio Tech rachets in their slightly outdated lever bodies? Or how peopl were using tailhook lengtheners to cobble together stump-puller gearing on road bikes?
Same thing, but for electronic groups.

I’d love to have AXS shifted ekar cassette with di2 levers or some shit
this is my question. it’s not like we have parts bin di2 and axs derailleurs we’re trying to use. i could see it potentially being helpful in the future when you can go down to the bike coop and get electronic parts to toss a bike together, but as it stands, i’m not following the application all that well. what’s one derailleur doing better than you’d need to mismatch it with a different shifter in this application?

is why.
Getting started with opening control of these components, and creating a community of expert hobbyists who can do this. I assume it’s already happening, based on @schultzor comment regarding the WW data dump.
as to more generally why, my above examples are what I had in mind. Let’s assume that electronic shifting is the emerging standard for everything above entry level (particularly for road). I’d like to be able to use what works for me / what I’m interested in.

when/if I decommission some of the di2 parts on my gravel bike, I might have a look at things…

Maybe a better use of energy would be to encourage future cyber groupset makers ( Sennsah etc) to make them open source or hackable?

or we get shimano/sram/campy to use their protocols to copy protect video content, they will be hacked in no time flat

folks want cyber-options
not that i care too much, but i could see elite-level racers/teams using wireless components having qualms with this development, and is likely why manufacturers want to keep the nuts and bolts of the software behind a dense fog

i mean if it were me i’d just have an open source version for the people and charge pros and those who impose for the norton antivirus package edition, but i think that’s probably way beyond what the big bike industry players have the imagination for

No, but we (the royal “we”) do have parts bin di2 road pushers & mountain danglers that we’d like to use on the same machine (and, in one case, visa-versa, though the direct mount that the mountain pushers use is wildly incompatible with a braze-on road dangler mount.)

There still isn’t a ready-made generic base for BOA dials, right?
ETA: looks like just a couple 3D printer bros

I imagine that if I wanted to, badly enough, I could make a Campy thing shift a di2 derailleur or vice versa. Thing is, it would take a fair bit of effort and would be costly, so barring a very good reason….

This is why I’d love to see it shift from capable individual hobbyists to communities with collective expertise.
