Would let their Di2 run flat on a Friday evening when their charger is locked in the office for the weekend. My name is Mister P and I am an idiot! It’s done well, that’s 6 months of riding on one charge. Please feel free to point and laugh.

I’m glad its not only me that does shit like this..

what gear does a flat di2 go to ?

Whatever gear you are in at the time. I’m not making any excuses, it’s totally down to me being a chump. And it’s especially funny if you know who I work for, hey Klunk?

6 months on one charge is great, but may be too long.
I know nothing about Di2 – guess its not a USB.
Could you drop it off at your LBS in the morning?

Oh, I was running a 26 and a 29er, had a box of spare tubes all rolled up. One day I had a great idea I’d write a 9 in yellow crayon on all the 29ers to make them easy to find.

Erm, Di2 does warn you it’s about to go flat if I recall correctly. Doesn’t it drop to the inner ring and refuse to shift up? The idea being that you’ve got your low gears to get you home…..

Single speed looks better and better every day…. 🙂

yes Di2 does warn you about low batt BUT you need to PRESS the button to find out! 😀

Good skills

If the bike trade didn’t close for weekends you’d have been able to get it tomorrow 🙂

Weren’t you on FB complaining about being surrounded by idiots this morning?

Ahem.

Brilliant post, thanks.

Nearly went Di2, had exactly this concern, loving my DA9000 😉

[/smug]

Where is everybody who said that batteries running flat on Di2 is a complete non-issue?

Mr P , why not pop down to to your local bike shop and get a free charge up.

I dId this exact same thing with my DI2 Alfine 11 last weekend. It was a cuffin painful ride home/back on Monday with the bike effectively stuck in 52:12.

I assumed that when it was on one bar or battery, it would give some clue as to it being close to runnning out…It didn’t. The bugger waited until I hit my first downhill, whereupon I shifted to the highest gear…that was my last gear shift for the next 55 miles.

I think the clue was the one bar…

what gear does a flat di2 go to

I claim you’re the idiot for asking such a Q.

I’ve seen 2001.

I’ve seen what happens when mankind goes fully automatic.

I’ll stick with my 3 X 9 thank you.

Having been exceptionally Di2 sceptic for some time, and having already pre-ordered a Red eTap groupset, I’m waiting for the moment I have to eat my words and attempt to ride the bike on a flat battery!

SRAM Red rox 😆

Oh, it’s lighter too.

And seemingly more reliable 😛

Cool story though.

Took me a while to workout what you did wrong there 🙄

Of course the original problem is crying out for a better solution. Now, if only someone made a device that would physically connect the the gear selector with the bit that actually changes gear, perhaps a piece of wire pulling against a spring, then we wouldn’t have problems like this 😆

Meh, di2 is brilliant. I’d rather have it and have to carry a backup battery than use snappy stretchy gritty cable
(On a road bike, that is – till we know the mtb works all winter)
It is just a lead isn’t it ?

In which case how do you get a gritty, stretchy, snappy cable? My mech stuff works fine after many years of zero maintenance.

I’m still struggling to see what he did wrong 😳

The moment I saw the thread title I knew I would be right at home here 8)

What number would he write on the 26″ tubes?

I’m still struggling to see what he did wrong

Imagine he approaches his box of tubes from the wrong direction.

😆 😳 I didn’t realise he had alzheimers too, he marked the 29ers with yellow crayon..

Ah, paved with gold is restricted only to certain postcodes round here; we have grit, rain, even road-glue round my way

You’ve really not adjusted cable tension, nor cleaned / replaced any gear cabling in many years ?

Nope

Indeed. Plus my handwritten 9s look nothing like a 6 when upside down, more like a b.
