New 105 Groupset

Meh. Am I ever going to use wheels with thru-axles? Nope.
As far as the ergonomics, I would be more excited if Shimano levers were more like Campagnolo. With Shimano STI, the same lever controls the upshifting and braking? What is it with that?
Also, they should move the shifter cables back from under the bar tape to the outside like the old levers. Less sharp cable bends and cable friction and fussy setup.
Finally, the crankarms are butt-ugly. I guess I can forgive, as Shimano crankarms have the best fixing and BB interface in the business. I use Shimano cranksets and chains on my otherwise Campagnolo drivetrains.

I didn't hear them mention any weights. But the 5800 105 was only about a pound more than Di2. And they've probably now improved on that.
I still have 9 speed 105 on one of my backup bikes, and 10 speed 105 on another, and they both function flawlessly. 105 is great value.

I tried the new Ultegra front derailleur when I built my latest bike. It looks and functioned okay, but the cable tightening screw broke off with part of the casting when loosening the cable. It is made from cast aluminum. I used my torque wrench when tightening the cable, an allen key when loosening. Luckily I had a 105 derailleur laying about.
Maybe the one I got had a defect in the casting. I don't know, but I did get my money back upon return of the part.

Horrific crank.
Im all for this though. Hopefully push rim brake tech to an even cheaper pricepoint.

Over the years I've had three different Shimano STI groupsets including my current 5800 11 speed. I've not had any issues with the design. Can you tell me what happened with your near-accident?

Great. I just finished putting 5800 on my old bike. Now I'm going to have to scrap the whole group and upgrade.

Some more blurb here:
https://bike.shimano.com/en-US/infor...-gear-ran.html
No weights though, but Im guessing its the same as before. R8000 is about an ounce more than 6800, AFAIK.
I think it looks like a solid update. Especially the hydro STI-levers. I like that it does 34t too, but I wish they would do a 105 sub compact crank. 50/11 is wasted on many anyway. Oh well, you cant get it all :-)

I have the 105 set on my Kestrel and love it. Shifts are quick and smooth. Adjustments are easy.

a car was suddenly swerving, I pulled the lever but instead it slipped and moved inward (downshift)

This got my attention...
Those who have been holding back because of the need to upgrade wheels should be interested in this.

CS-GH700-11 11-34T cassette also fits 10-speed freehub body

Oh well. I figure 2 years is long enough to amortize my 10 speed STI, then it's off to 11 speed hydro I go.

I cant think of a time where i was having shift and brake with the same lever at the same time.
I have a set of Microshift levers on an old roadbike and they have a dedicated up shift paddle, down shift paddle, and brake lever. I like the set up a lot, but not because it is somehow safer. I also havent tried shifting while braking with those shifters either.
What do you use instead of Shimano...Campy?...i guess SRAM is an option, of course. I used SRAM once to ride a bike around the block that id worked on for a buddy. Interesting shifting style. Easy to adjust to. Didnt seem good or bad, really.

How did you almost have an accident from a shift lever also being the brake lever?

Yes, this cassette works because it offsets the 34t back behind the freehub body. Anything smaller won't clear the wheel spokes. All of shimano 11 speed mountain cassettes will work on a 10 speed hub because of this design

I happen to use a wolftooth roadlink, so the short RD would definitely accept 34t, then I just need to upgrade the right shifter
