Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

I mean I'd never contemplate SRAM for ultras but how big is the SRAM charger in that setup?

Why run a 1x w/ FD, just carry the spare battery, no?

EDIT: Oh, you mean you would have the use of just 1 front ring while it charged. I get you.

I wonder if anyone is researching how to jailbreak their free power meter, would be cool to see. I'd imagine it would be possible

Everything is possible.

Thanks. I was worrying over nothing.

Guess you can't charge and ride but not a big deal.

It is if you're stuck up a mountain and need to get off it.

If you're stuck up a mountain, you can freewheel off it. You don't even need a chain, much less derailleurs 🙂

You're halfway up, the town with the food is over it on the other side.

In which case, there is no mountain high enough in the world to stop you getting there.

Anyway, my batt went flat on Hoosier in the TransAm and I plugged in the charger and kept riding with gear changes. Go me.

Earn your food by pedalling up in whatever gear you’re in.

Sure. 56x11 like everything else but you know, some riders aren't as strong as me.

This is what I immediately thought. There will be a way for sure.
Haha get it unlocked on the black market. Someone will know how to do it and could charge a small fee. Smaller than five hundred quid anyway

Surely the electronics aren’t in it!?

Ha that's possible. But the wording 'unlocked' suggests they are to me.

They are. The power meter spider is an integrated unit with the chainrings, and you pay to unlock the firmware in the power meter. When the chainrings need replacing, you return the whole thing to SRAM for a half-price replacement.

Another reason not to buy SRAM gear. As if there weren't enough already.

On the sigma website the two models look different is all...

Who on forum has the required mad unlocking skillz???
Would be interesting to see if it happens. Have absolutely no desire for a power meter especially an integrated one. But would love to see it hacked.
Anyone one a bit more knowledgeable want to chime in?

In the moden enlightened period of waste reduction this really irks me.

Totally. They claim they will recycle old ones. But I still call bull shit. Not integrating it in the first place wpuld have avoided the problem.

Maybe integrating it uses less material and energy for production, and refurbishing uses less material and energy than making replacement chainrings. If that is the case, then it becomes a question of whether shipping it back for refurb is a bigger cost than the saving achieved.

Yeah, that's true. An interesting point. It's certainly possible that's the case.
But I'm a little cynical. I'm not sure I believe sram would go to that length. I think profit margin is the bottom line.
Of course I'd love to believe otherwise, but if sram really were doing this with waste reduction at heart then I think they would be shouting out loud about it. It would certainly make then look good.
I wonder if they would publish any data on materials and energy used vs it being integrated.
Would be a very interesting topic of they could actually show a real waste reduction.

I suppose integration possibly has cheaper production costs for them though.

I see. Interesting. Not entirely sure what the point of any of it would be without the mechanical parts at this juncture.
Retailers also seem to simply dump any picture of the group set as the leading image.

I'm a little cynical

Probably not as cynical as I am, I was just proposing a mechanism whereby integrating the rings with the PM was not necessarily wasteful. The truth is that SRAM are about profit maximisation, like any company should be. If they were a "green" NGO, they'd be telling people to stop wasting their money on power meters and and other racing parts, 99% of which are used just for bicycle cosplay.

Sram Electronic/Hydro kit have only two options (flat and post mount), sold indeed in distinctive box, while chainsets and cassette are three each and considered add-on, all cross compatible so it would make it impossible to offer a package with all these options.
Shimano doesn't care and doesn't sell full group sets, it's up to retailers to find individual parts and offer them online as a complete group or di2 upgrade kit only.
I agree though, it is annoying that shops use pictures of complete AXS group sets when they are only selling shifters, brakes, derailleurs, batteries and charger.
