Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

Did that guy leave his bike on the back of his pickup and take it through a car wash?

Di2 Ultegra 12 speed question: I know the shifters can be set up wirelessly or with wires. With wires, there is a claimed 50% increase in battery life.

The claimed battery life is 1,000km so does this mean that the battery life with the shifters set up WITH wires is 1,500km?

Sorry if this seems an obvious answer but I just wanted to double check. For long-distance riding/audax it seems well worth the hassle of setting up the wires for improved battery life.

I got 1800k out of my 11spd, both years I did TransAm. So, 1500k seems a reasonable value - sometimes more, sometimes less. I would definitely set mine up fully wired. You will give zero fucks about your 'clean cable routing' when your shifters stop working and you have no spare batts.

Awesome.

I’ve never really worried about battery life on my 11spd Di2 as I never did a ride longer than 300km on it so just charged the night before. I did a 1,600km tour of Scotland over a week and just took the charger with me which is what I imagine I’ll do on 1,000km audaxes anyway.

Wires it is!

Interestingly, you can keep the small batteries in the shifters and if the wires ever fail for some
reason the shifters will automatically switch to wireless.

I generally carry the charger on all my 'big' rides. I guess that means anything over 600k. Even if not for me it might help someone else out. My missus has Di2 now too so it makes more sense, just in case.

That's neat. I've had my shifting go wonky (intermittent shifts) on a TransAm as one of the connectors ended up full of swamp juice (sweat, tears, snot?). Once it was popped and cleaned it was fine.

12 speed charger is just a wire too so way more convenient to carry than the old 11 speed block

Interesting. I want to get a Di2 GRX groupset for the grrl's (:-*) new gravel bike. I was going to get 11spd because that's what I have on pretty much everything else but is there any other improvements? Actually do they do 12s GRX Di2 bits? Really need to get googling again.

Can the 12s charger work with 11s stuff? Or will we need to carry 2 chargers?

whats wrong with campag? 😂

You'll need two chargers. Different connection on the new one. Mag connector on the derailleur

Fuckers.
Now I have to work out some way of upgrading my bike and giving my missus my old stuff..

Might just stick with 11s

My 12spd Ultegra groupset arrived this morning and I’m pleased by how small the charger is.

Does this mean it can be charged from a power bank? Or only from mains?

Yeah, this is my thinking too. I’ve seen too many people asking to borrow chargers on audax Facebook groups to not carry one myself.

Do you have a pic?

12spd on the right, 11spd on the left.

I guess the new cable is a bit more chonky but at least that little box thing is gone.

And to answer my own question, you can charge Di2 from a power bank.

I guess the new cable is a bit more chonky

You could probably fold it in half and stash in in your handlebars through one bar end for a long race scenario

Beat me to it! I was assuming you can, given you can 11speed.

Big problem with 12 speed is that you can't charge when you are riding, though, so I'll stick with 11 speed until it all dies!

@PhilDAS I like your thinking!

@frank9755 This is one downside. Is that just a physical problem though, ie the charging port is on the rear derailleur? I guess if you’re running a saddlebag you always run the cable from that, wrap it around the stay and into the RD?

Is there no way around that charging on the move issue? Why did they move the charging to the RD?
There's no way I'd be dangling bits off the back of the bike to a moving RD to charge.

Because there's no junction boxes any more and only the two derailleurs are attached to the battery so it has to go via one of them

The whole system is literally just shifters attached to nothing, two derailleurs attached to a battery with one wire each. Done. Don't need 8 wires and 2 junctions any more.

What's at all worrying about having the cable ripped to pieces by your rear wheel in the middle of nowhere during a moving emergency charge?
