Dura-Ace R9200

What an odd complaint since it's just your first shift and is easily avoided by waking it before riding. I press the shifter a few times before I start riding to get it to connect to Garmin anyway. Once riding, shifting will always be quick. Shouldn't be difficult to remember a press before riding. Sounds to me like complaining that Garmin doesn't turn on by itself and should add a camera just to enable this.

Garmin don't sleep during a trainer ride, a steady state flat ride, or a cafe stop.
Wireless Di2 do. Maybe you don't have my terrain where it's a flatland and sometime I ride half an hour on service road without any shift. It literally sleep during my ride... Then when I want to shift going up the overpass, I found it sleeping.

I’m sorry, but you need to grow a pair. How hard is it to make one shift to wake the system up?

It's not hard. It's an annoyance, not a deal breaker that cause me any race. But that doesn't change what I stated. The system perform better wired. The Di2 wireless mode implementation has its quirk on a well known, been solved usability annoyance, almost like its an afterthought.

It says ST-R9250 and ST-R8150 on page 18

Depending on the handlebar or stem, you may be able to put it in those... I have one here at home I think, but haven't measured it. May be able to do so tomorrow, depending on how I feel. We seem to have caught covid :}

Of course it does, you are quite right! Feel better dude, understand your website and forum time are a labour of love and not a priority!

Shimano says it's 32.5mm x 11mm x 9mm.. I measured mine and it's close enough

^ Seems smaller than EW-WU111.
That's definitely small enough to go inside Specialized Aerofly II and Enve Ses Aero road bar, and many more common aero road bars.

Awesome info, thank you!!

Wish they'd do a 3-port junction (unless I'm being daft again and not reading correctly, I don't think one exists).

Two ports on one end (for the shifters) and one port on the other end for cable into the frame..

[Hexsense]

I don't think a 3 way junction for SD300 wire would be noticeably smaller than the 4 way shown above.

Maybe consider the 4th one a future proof port for TT extension shifter?

hi, anyone using Rotor NoQ round chainrings with 9270/8170 groupsets?

Rotor official website still displays NoQ with only 10s/11s compatibility. Not any update.

Works flawlessly on two of my bikes.

So I've got the first 12 speed setup in da house, but in a TT variant, that is, the shifters are R9160, so the only possible shifting mode for FD is full syncro.
What I haven't figured out is, how to microtune the FD? Is this even possible in this situation? All the videos around use the front shifter for that when in adjustment mode, but in the TT setup, of course, that's not available.

Use you phone

[marcelflash]

For TT wire with extra sprint shifters SW-R9150. Use phone to configure 1 button for "function" button like rear derailleur button and the other for up or down.
Maximum is 6 buttons then you still have to have 1 extra button for not to use syngro shift.

I've used Campag and SRAM electronic groups before but DA Di2 12 speed is my first experience with Shimano. I'm having difficulty getting the levers to pair with the system and of course I failed to do the pairing before installation but I haven't bled the brakes yet so not too big of a deal.

I managed to scan the QR codes on the levers using the app but the levers aren't shifting. I pulled the levers off again and connected them to the battery one at at time via the FD cable. This partially worked - when I paired the left lever in this manner it worked immediately and I thought my woes were over but when I paired the right lever in the same manner it also worked but then left lever stopped shifting again. I repeated the procedure with the same result, the levers appear to only be pairing one at a time.

Looking at page 478 of this thread and onwards it looks like I may need to do a firmware update on these levers. If my understanding is correct, if I connect a third cable to the battery and then plug one lever into this cable and the other one to the FD cable they should pair simutaneously? Any advice would be gratefully appreciated. Many thanks.

Has anyone been succesfull using 52/34 up front (as opposed to 52/36)?

Have not tried it on 12sp(yet).. but my buddy and I are both running that setup on 11sp.
