I am not sure if this is true.
Didnât they change all the battery connectors?
If thats the case, it would be not be possible to use the FDâŚ
How do people see the gap between 105 R7000 and the new ultegra R8100 being filled?
Are they going to keep making the Ultegra R8000?
- Yes, that seems to be the assumption (stated by James in the CT review at least). Not sure we have âofficiallyâ seen this stated, but it seems plausible and something I and many others are hopeful to see at least for a year or two.
Did I see that price right, $2500 for Ultegra? I paid $1450 for my R8050 including the EW111 module, all wires and junctions, charger, plus crank/cassette/chain/calipers/everything.
Am I looking at pricing wrong or is that 12th cog really really expensive? Is that $2500 including wheels and/or a power meter crank?
Also think the whole âwireless for disc brakes but wires for rim brakesâ makes zero sense, id think it would be harder to fit the wireless shifter transmitters in with a hydraulic reservoir in the STi lever but apparently itâs backwards?
As someone content with the reliability of Shimano 105 I find this upgrade a bit of a race result randomizer.
Hearing all the stories about electronic shifters failing in critical moments (especially losing power) I always wondered if they were worth the money if your main concern is how quickly and reliably you get from start to finish. I know these things donât happen that often and that mishaps are often a result of user error.
Still, this update leaves you with no mechanical option, and with wireless communication which will be⌠more reliable than a wire, or less? And a compulsory 12-speed chain which will wear out faster and break easier than an 11-speed. You happy, sprinters?
Oh, and no SRAM compatibility. So when you need to replace a cassette quickly and your LBS has no Shimano (or thereâs a limited supply of parts in general like we saw in the recent months), youâre out of luck.
If the shifters and the FD are connected to the old junction B, you could connect an adaptor between the junction B and the new battery. The new RD is connected directly to the battery, and not via junction B.
Or you could use multiple adaptors.
Given Shimano provide an adaptor, clearly the wiring is compatible. The question is whether the road shifters and FD are blocked at the firmware level, or whether it is merely discouraged.

There is a firmware update involved to be able to use the TT stuff on the new system.
But, IDK
At some point, someone will try and we will have the answer i suppose.

That blame lies at the feet of SRAM, not ShimanoâŚSRAM were the ones who moved away form standard chain pitches / designs.

Where are you getting this from? Sram 12s chains are more long lasting and durable than anything else out there, by a LONG shot, so more gears doesnât equal weaker chain.
Also agree on the above, SRAM is now using 2-3 different chains for different applications which canât be mixed (AXS road has larger rollers than Eagle even though both are 12s). Combine that with the overlap in all the derailleurs they now offer Iâd say SRAM takes the cake for trying to do things differently just to say theyâre doing it different

I do! It makes the drivetrain super silent and doesnât affect shifting negatively in the slightest.

Why would they want to sell $100 updates when they can sell $500+ shifters? You would only be undercutting your earning potential. You wonât substantially increase your market penetration by offering that option.
Now, could there be a âsweet spotâ between the two? I dunno, maybe. The âbestâ option if they want to do this would probably be in a few years as a way to incent the holdoutsâŚand I suspect that there will be a decent number of people that fall into this category.
I have no need for 12 spd and certainly not at these pricesâŚheck, I only went to 11 spd in 2018.

AbsolutelyâŚ
There is no incentive to allow this. The hold all the cardsâŚ
I was just given an example of a âgoodwillâ token a company could doâŚ
But as you⌠i just got an 11 speed bike few months ago⌠no need to upgradeâŚ

The last compatibility break from Shimano Di2 was 2014. I donât understand the frustration.
OK guys, youâre right⌠nonetheless, with an 11-speed drivetrain a SRAM chain would still work wouldnât it?
I just hope they wonât âupgradeâ 105 is all. Let the top-end gear aficionados have their electronics and fancy stuff - leave my simple mechanics alone, unless there is a new Tiagra that is a copy of the old 105, then fine.
I thought you werenât interested in Di2 anyway?
I meanâŚ
My current bike is Di2,
Maybe I would be more interested in a 12 speed system in 2 or 3 years⌠who knowsâŚ

They are allowed to drop support for legacy systems. If they donât have compatibility breaks they would have to be figuring out how to piecemeal 12spd stuff to 10 speed stuff. They arenât bricking your stuff, itâs no worse than it has been in the past. Being able to plug and play parts across 7 years of releases⌠is pretty damn good.
They didnât even go to microspline to âforceâ you to buy new wheels. They are supporting rim brakes even though there is basically only Pineralleo making a top end rim bike. They have no motivation to support people that are never giving them money anyways.

You are making a ton of assumptions here.

2. Challenge the idea, donât attack the person
3. Contribute Constructively
