I wonder if Shimano will backtrack on their no more Ultegra mechanical move and release a R8100/R8120?
Should we assume that the 105 Di2 will be 12 speed? I wonder what Shimano will do to differintiate the three Di2 groupsets. I'm sure there will be some weight differnce, but currently that's the only real differnce between Dura Ace and Ultegra 12 Speed. When I heard they were going to release a 105 Di2 I wondered if they would re-badge 11 Speed Ultegra Di2 instead of making it 12 speed.

The pictures say 12-fach which is German for 12 speedMocs123 wrote: ↑Mon May 09, 2022 2:47 pmShould we assume that the 105 Di2 will be 12 speed?

Personally, I'd like them to make 105 Di2 R7170/R7150 12 speed to drive 12 speed cassette adoption and then release a Tiagra Di2 R4870/R4850 11 speed based on that downgraded Ultegra Di2 R8070/R8050 technical base to push electronic shifting to an even lower pricepoint.

Perhaps, they might release 105 12 speed in both Electronic and Mechanical, then Tiagra would be 11 speed mechanical

And maybe sora up to 10sp
Then Shimano Will have wider range of choice which really good

2023?? LOL.
If you want 12-speed mechanical, Campy just keeps looking better and better...

The current Tiagra 4720/4700 is actually an 11 speed groupset in disguise as the levers/derailleurs use 11 speed pull ratios rather than 10 speed.Vincentsmoox wrote: ↑Mon May 09, 2022 5:52 pmThis make senseStiffWeenies wrote:The pictures say 12-fach which is German for 12 speedMocs123 wrote: ↑Mon May 09, 2022 2:47 pmShould we assume that the 105 Di2 will be 12 speed?

So if a future Sora R3120/R3100 is indeed derived from the Tiagra 4720/4700 technical base, one could easily throw together a dirt cheap 11 speed groupset with a pair of 11 speed shifters (OEM or even third party like Microshift Centos or Sensah Team Pro).
