Di2 Synchro Shifting

Deagol

Hi all, anyone tried to upgrade their Di2 system to Synchro / semi synchro shifting?

When I try, it keeps telling me the FD-9070 / RD-9070 needs firmware updates but I'm on the latest version. I'm at a bit of a loss to understand it, I was sure they said 9000 series could be upgraded to synchro shift?

I think you are right. Check you have the correct components here? [edit] You might need a new battery.

Go to the following site and search "Synch"

It looks like all the components Firmware are V.3xx except the Front and Rear derailleur which are both on v2.6x.

There's nothing really helpful in the compatibility chart that I can find. I looked through the whole e-tube thing before I posted but I'm just mystified as to what the issue is. (Other than that Shimano haven't posted the firmware yet!).

And yes, I have a wireless unit, though i'm not sure what that matters? Did you spot something I missed I'm wondering?

Apologies, I misread the wireless bit. Based on the firmware stuff here http://e-tubeproject.shimano.com/firmware/ your FD/RD should be at 2.62/2.63 respectivly.

Is it an external battery you have or internal?

OK, I actually read that article a few months ago but the Q&A's at the bottom where helpful.

It appears my battery needs to be replaced to get Synchro to work, why a battery makes a difference is beyond me though.

Thanks for your help, appreciated.

P.S. For reference. I have SM-BTR2 battery. Looks like you have to have the BT-DN110 for synchro.

For the external battery, the holder is the brain, believe it or not. For example, If you upgraded all your firmware and lost the ability to "mix/mash" bits (10s with11s and Ulegra with DA), you just need to get hold of an old Battery holder and not upgrade the firmware. Safe to assume that brain is now "part of" the internal batteries.

I did come across this bit too, which might help you.

Synchronized Shifting and Bluetooth Wireless Units can be added to all E-tube Ultegra and Dura-Ace systems but the battery has to be upgraded to the BT-DN110 Internal Battery or BM-DN100 External Battery Mount.

That might be the handiest way?

[edit] Apparently the external yoke is MTB only

Tomorrow I hope to find out my bike has the right battery!

Deagol

I'll keep my fingers crossed for you .... the DN110 is €109 :eek:

Are ye using the synchro shift since guys ? Just enabled my ultegra di2 last night and have fully sync turned on and working.

I'd like to try it but I'd need to change the battery. Apart from the cost it looks an awkward job in the Canyon.

Seems to be - so that would be a new BB as well and apart from getting it out I'd say there would be great craic manoeuvring it back into position too!

Is this just a software update or do you need to add something? (assuming the battery is the correct one)... in work so not enough time to read the link

Just a software update, takes 10 minutes to do.

Ill ask a friend of mine as he had a faulty battery in his canyon a while ago and had to swap it out and did it himself so ill ask how big of a job it was.
