It is not old 11 speed compatible. It is intended for use with 12 speed spacing 11 speed that never came to market.rides4beer wrote: ↑Tue Jan 21, 2020 2:55 pmGood to know, thanks!eins4eins wrote: ↑Tue Jan 21, 2020 11:47 amI use it with di2. Works perfect.

I suspect it's because MTB components see more abuse than road components do and the sales volume may not have been there to justify it. XTR DI2 was expensive and perhaps many folks weren't so excited at the increase chance of incurring damage on such expensive kit.
Couldn't it be what? await the departure of Dura-ace 12?.........with the XTR 12, they would not have any new developments.........BdaGhisallo wrote: ↑Thu Jan 23, 2020 11:10 amI suspect it's because MTB components see more abuse than road components do and the sales volume may not have been there to justify it.

I ask, from ignorance
in the patents that are published you see "things" but nothing definitive, just ideas ...... that can see the light, or not
In road applications the occurrence of excessive potentiometer noise causing constant PLL variation which in turn can damage batteries or worse,cause motor failure can remain at a level that is still considered acceptable by many users. In most cases it passes unnoticed and is experienced only as the odd faulty battery or derailleur quirk.
In MTB applications though, this problem becomes evident rather quickly and is clearly experienced as a faulty derailleur (which in any case is exactly what it is). This has put many users away from the system and i think Shimano did the right thing discontinuing the product before it tarnished further their reputation.
Or simply put: with road Di2 you can have a malfunctioning RD and not know it, with MTB Di2 you will wind out, most likely quite soon.

I would assume that Shimano simple found out that they sell to little XTR di2 and stopped producing it for the current generation. di2 on MTB side had to be more agressively priced (in comparison to Road di2) to be competitive with SRAM so it was most likely financialy unsuccessful product. But they might reintroduce it in next generation with semi or fully wireless di2 since SRAM went to Eagle AXS and finally increased the prices of the top groupset.
Functionality > Performance > Weight
Lol. Given that my usual routes are up/down a couple of mountainous areas with speeds up to 85km/h, I don't thing I'd ride a bike fitted with wireless brakes.Dan Gerous wrote: ↑Wed Jan 08, 2020 12:08 amProbably not for non-motorized road bikes... And think of it, brakes requiring battery power and electronics can't be a good thing. If your Di2 battery dies on a ride, it sucks but it's not that bad, you survive and get a story to tell about that time you climbed 2 cols stuck in your 53x16... if you run out of battery on your brakes during a ride? You might not be able to ever tell that story!madik wrote: ↑Tue Jan 07, 2020 11:56 pmdi2 brake is quite interesting. Its not wireless tho So its basically brake by a wire system. Calipers would be pretty huge and expensive since it includes some electronics, electronic motor, lots of gears to drive the hydraulic piston. Not sure how much it could be miniturise.

Di2's biggest advantage is fast and precise front shifting. Why complicate the system when most of new XTR users are running 1X? I'm sure many Shimano engineers believe in the same thing.madik wrote: ↑Thu Jan 23, 2020 2:39 pmI would assume that Shimano simple found out that they sell to little XTR di2 and stopped producing it for the current generation. di2 on MTB side had to be more agressively priced (in comparison to Road di2) to be competitive with SRAM so it was most likely financialy unsuccessful product.
