Di2 Cheat Sheets are here!

[decade]

Hi
A unamed person in my house is fond of cross chaining her 9150 Di2 kit 50 front ring with the 34 largest cog (yes I know it the 11-34 not officially supported but it works). However quite often when in the 50 and 34 the chain drops to the smallest chainring. My question is, can I use the etube software to block her using the 50 and 34 in combo?
cheers

Unfortunately, no. But you could possibly enable synchro shift which will disallow the big big combo.

Hoping someone can point me in a direction to troubleshoot my di2. I have 11 speed Di2 Ultegra factory installed on a Specialized SL7.

My problem is the battery drains in about 2 weeks, often leaving me stranded. I just fully charged on August 14th and it died on me this morning, Aug. 31. I took it to the shop, and they replaced the seatpost battery under warranty, but this didn't change anything.

What can I, or what can I ask my shop to do to diganose and fix this issue?

Try swapping out the E-Tube junction. I've had two of those go bad over the years, and they lead to accelerated battery drain.

With the bad initial batches of cassettes, was it the 24T on the 11-34 that was typically giving people issues? I remember it being one or some of the higher sprockets.

Using one of the early batch 11-34 DA cassettes at the moment, and the 24T when matched with the big ring makes drag and stuttering noises all the time. It feels awful if you put more than 200W on it, so I avoid using it. It's not perfect in the small ring (though much better). The cogs above it (even the 34T matched with the 52T) are perfect. It looks like it's too close to the cog above it and the chain is hitting it - though I'm not 100% sure this is the noise. RD is trimmed properly and the FD isn't touching the chain.

Hi all. Question for the group.

I love the "idea" of Sycroshift and tried it on my Di2 Groups. The issue I had was that I could not replicate via programming my shift behavior when starting up a hill...which is:
- shift the cassette up 2 gears (harder)
- drop to the small ring (easier)

Syncroshift did the opposite sequencing so I'd spin up crazy fast then it would add 2 gears up on the cassette. Can my preferred behavior be replicated on the newer 12 speed groups or is the programming the same?

[TerryDi2C]

You cannot change the order of shifts, no

I have 6800 series di2 tt groupset with the 2 button extension shifters. I have an external battery as an internal won't fit in my frame. If i buy the new external battery mount (bm-dn100) and a bluetooth module(ew-wu111) can i use the app to reconfigure my shift buttons? Is there an easier way to reconfigure shift buttons without buying the diagnostic module?

[TerryDi2C]

Yes, if you buy the BM-DN100 and the EW-WU111, then you can reconfigure things using the app.

Alternatives...

If you have the SM-EW90-B 5-port junction, you could also buy / find on ebay the SM-BCR2 charger. It won't charge your bike, but will act as a PC interface and let you change settings using e-tube project 3.4.5 or 4.0.4.
(Just do NOT update your battery mount using the SM-BCR2 )

Terry,

I have just finished an R9200 DI2 rim brake build and I can't figure out how to check the charge on the battery.

Do you know how?

Cheers,
Geoff

I believe it's one quick press of the button on the RD. I also add a 'battery level' field on my Garmin GPS so I could see the level in %.

Did you look at the original post in this thread? That's quite literally the information posted

No, I must admit that I didn't. I was lazy.

I am thinking about mounting sprint shifters on my aerobars on my roadbike. I have ultegra 8100 12 speed.

I understand that the DURA-ACE SW-RS801-E has a 740mm length that will fit well, but i can just find the shorter variants online. Will the sprint shifters accept a extender cord with a SD300 cable? So that i can use a RS801 100mm and extend with a cable?
