105 Di2 is here

I guess one could just use ultegra shifters (8100) with the 105 groupo, right?

Some riders liked installing extra shift buttons on the drops for sprinting use. Other riders wanted buttons near the stem for climbing. 105 will not accommodate that.

There will only be hydraulic brakes on 105 12 speed. No cable pull on the lever for the brakes. Electric shifting only.

It just doesn't make sense to keep making it.

If everyone on all these forums actually bought new rim brake bikes, we would have rim/mechanical.
When it comes down to splashing cash, EVERYONE specs disc and electronic.
105 now brings that to SRAM Rival pricepoints, which they really needed to fill in the gap.

Simple fact is Shimano isn't going to make new product if there is zero demand for it.

SRAM has done the same thing. They've abandoned mechanical, etap and only offer AXS now.

The issue now is this new 105 groupset has pushed bikes up a bracket to a price point some or many may not want to pay. I certainly wouldn’t pay the current rate for this on a complete bike. I would rather Ultegra or just stick with Campagnolo 12spd mechanical.

These mod groups, and I mean disc, sure are hefty. You need carbon wheels and super light frame to get it down decent. It is not my bag baby. I mean compared to mechanical, like a bunch of grams added. Too lazy to look up, but considerable.

Add to that not aero and a PIA. My coin cells are dead, my battery, mmmm, yeah.

My first legit race bike was a Cervelo S1 with Ultegra for 2200$. We need high-performance bikes at lower price points to get young people who aren't super wealthy into the sport.

Caad Optimo with 105 for MSRP $1,625. https://www.cannondale.com/en-us/bik.../caad-optimo-1

Allez Elite with Rival 22 for MSRP $1700. https://www.specialized.com/us/en/al...=322264-199474

Rim brake bikes every bit as good as the ones that used to be available, for essentially the same money or less adjusted for inflation.

Over the past decade, the market has expanded tremendously at the top. If you judge where you are in relation to the top of the market, then yes, it's gotten a lot more expensive to be in the same relative position. But if you judge these bikes on their absolute merits, they are every bit as good as what you could get a decade ago for comparable prices.

There seem to be a lot of folks here who seem to thing that wanting disc brakes or electronic shifting are frivolous luxuries forced upon the public by marketing executives, but wanting a groupset that's marketed as "top tier" isn't.

So will Campagnolo release one further mechanical and/or rim brake generation? It is hard to imagine that it makes sense as the majority of the frames will most likely be disc and electronic only going forward.

Weird. Someone on another forum (who has had some reliable and, so far, accurate info pre-launch) has said there is a mechanical 105 12 sp hydro group coming as well.

Time will tell!

am I correct that R7100 costs more than R8070, weighs more, missing servo wave, missing free stroke adjustment and limited to gravel sized cassettes?

However, you get an extra cog and wireless shifters.

It has free stroke.

[TerryDi2]

Yep, free stroke and reach adjustment.

If I were to build a 105 Di2 bike I'd probably use ultegra levers though... not having the hood buttons and not being able to plug anything into the levers doesn't really work for me

Kinda inevitable, higher $ for electronic, all wet disc all the time. shimano is all about OEM and sticking it to sram OEM..their market isn't groups that get put on frames by bike shops or individuals.
Ultegra electronic about same $ as DA mechanical..
Record EPS about the same $ as SR mechanical...
105 electronic about the same $ as Ultegra mechanical...about the same $ as Centaur mechanical.....

Many people believe there is still a potential mechanical group that will be offered that is not Tiagra.

[Big Dan]

I think new riders are going to eat this up.
Disc brakes like your car and no cables to adjust!!!!

I already have a set of DA ST-R9100 in the drawer for the Firefly, and I just today bought a new set of Ultegra ST-R8020 on eBay to put in the drawer for the Bingham. I don't get along ergonomically with Campy levers, and 11 speed works well for me with the HG800 11-34 cassette, which I have a few of in the drawer.

I decided the cost of stocking up a bit is small relative to the value and enjoyment I get out of these two bikes, which get the most miles of all my bikes. I also have a complete SRAM XX1 11 speed drivetrain in the drawer for my FS 29er.

No strong value judgement about e-shifting, I'm sure it works great, but the mech stuff works great too.
