Which Groupset?

Have a look for KCNC jockey wheels as they make a 13t .. But as Kimmo said alloy jockey wheels do then to be noisier then plastic

this is really interesting - bring wireless shifting to your 1x bike

pls stop

Did you fix/replace it?

sorry but that is one of the most innovative cycling products I have seen in a while. wonder if it is actually good though ?

Worth it for that MASSIVE ergonomic shifter alone

I'm sure everyone has seen these already? Cranks look awful to me, at least the hoods don't seem so big as on the DSM bikes.

this happens every year with bad renders, generally with Argon 18

whatever it will be, it will grow on us and we will buy

I'm glad they're removing cables and last gen road discs. Cranks are surprisingly rank, even by Shimano standards

IMO, if anyone was choosing between Di2 and AXS right now, it’d be insane to go with Shimano. Especially now that renders have been released. Don’t get me wrong, I know it performs incredibly well but having etubes routed through a bike with a battery in a seatpost just seems so dated versus what SRAM are doing. This is not taking parts availability into account. Merely talking about functionality.

Completely agree. Axs isn’t prefect but against messing about with wires through the frame it’s a no brainer.

It seems there’s must still be some sort of patent issue preventing Shimano going full wireless.
I can’t believe they would choose to use wires from some sort of functionality perspective.

any idea when AXS availability is going to stabilise ? how long is a piece of string ?

I sent an axs post in for warranty in January. Still don’t have it back.

SRAM uk tech centre told me they have some coming to them in September and will try allocate one to me.
They said rest of stock going to the distribution warehouse for December apparently.
I think this is the case for a lot of sram stuff not just axs.
All anecdotal but I’d guess early 2022 by stock levels start to look close to normal 🤷‍♂️

The interesting part of the availability issue is that with Shimano it's somewhat understandable. Irrespective of factory shut downs, they have a huge OEM market. 90% of their parts go to bike manufacturer's, so delivering individual groupsets to be sold way under MSRP at Merlin is not their priority. But SRAM don't have that excuse. Their OEM market is tiny tiny tiny by comparison.
It's interesting how long SRAMs lead times have been for well over a year now.

Sure, but that is a few hours of fuss for a system that then works better - more reliable, better shifting.

Functionality while riding surely more important than functionality while fitting - especially given how many people buying groupsets won’t even fit them themselves?

Sure, but that is a few hours of fuss for a system that then works better - more reliable, better shifting.

That's very subjective, and not necessarily true.

OK - has been my experience and all those friends i have spoken to who’ve also used both. Whereas I’ve not yet encountered anyone who thinks SRAM shifts better than shimano

It's not just a few hours of fuss though. There's a lasting impact on the frame. I guess I was speaking from a very personal point of view, but imagine if in 2021 you spec a custom frame for Di2. It's just way less slick than AXS. Holes in tubes to accommodate etubes that simply don't need to exist with AXS. Say you spec Di2 and then Shimano release wireless shifting in the future. I'd be bummed out that I have these pointless holes.

And is it more reliable? Shimano have had so, so, so many warranty issues on modern Di2 parts. As far as I was aware, eTap is a pretty reliable and mature system now - just as much as Di2 is.

Modern Shimano stuff is getting uglier and uglier IMO, too. They have no native crank based power and have killed off Pioneer, whereas SRAM have crank based power all the way down to Rival.

Dunno. Just think they're sitting on their hands, while SRAM are actually moving forwards.

But then all of that is moot because my bike and my upcoming bike will both have rim brakes and mechanical Chorus :-)

I run both. I think SRAM's shifting is fundamentally more intuitive, from both a lever and derailleur perspective, and is as reliable as Di2, if not more so. I'm in my 6th year of running eTap with no issues whatsoever. It's been totally flawless.

Yeah I can see that, but for the vast, vast majority of people that isn't the case and they're buying a groupset to go on a frame they have. I actually did buy a custom frame made a couple of years ago, specced it with di2 and then put etap on it... And am not annoyed about the holes. They mean it's more versatile and I have choices. But I do find that etap doesn't work as well.

This is fairly minor stuff - I've not had full failure on either system, but the Shimano shifting has always been crisper, faster, and doesn't go out of alignment, whereas etap front shifting loses the chain all the time, despite multiple bike shops having tuned it.

Friends on axs have similar stories - yes it works, but isn't as quick to shift or as accurate in shifting, more often is slightly out of true and makes noises, etc.

I dunno. Whether my frame has a hole I'm not using is more or less just aesthetics, whether my bike throws the chain at the bottom of a climb when I'm changing chainrings is a proper performance issue

Yeah I like the shifting for intuitiveness, but I have to think more about it as the front shifting is so much less reliable.

Happy for you if you find it better. But I have spoken to loads of people who think the shifting is less good and you're the first whose said it might be better...

I have Force AXS on my SuperSix, and DA Di2 on my Talbot…. I think both are pretty faultless TBH. I was unsure of the whole using left for up and right for down thing on AXS to begin with, but have got used to it now…. Wouldn’t say I prefer AXS to Di2, but deffo don’t think it’s ‘worse’. AXS does require a little more effort to keep it running smoothly though….. but nothing like the regular fine tuning needed to keep campagnolo happy. Talbot is rim brake, so can’t comment on braking comparison, although my old Volare had hydro R8070 Di2, and the braking was better than my SuperSix I think, but that may be down to the Ultegra levers suiting my hands a bit better.

The only thing that would make me choose AXS over Di2 on another bike would be the wireless aspect, but if 9200 has wireless connectivity between the levers and the mechs as speculated, I’d choose Di2 over AXS for sure. I much prefer the look of Shimano (on a modern bike at least), I get on better with Shimano lever ergonomics, and replacement parts are much more affordable!

I think SRAM's shifting is fundamentally more intuitive, from both a lever and derailleur perspective, and is as reliable as Di2, if not more so.

Likewise. I have both 11 and 12 speed etap. Zero issues.

@andyfallsoff

Is a difference in shifting speed really noticeable? Something that happens in hundredths of a second! I think overall the difference between the two is vanishingly small.

Strange about the front derailleur. Have seen reports of this online but it’s always an incorrect set up issue.
I’ve never had any chain dropping issues with mine.

Edit for balance:
The sram 12 speed Mtb cassettes can be loud and clunky compared to shimano though
