Wow I didn’t even realized the Crux was not UDH. Guess I’ll be waiting to see if the next Crux is compatible with XPLR transmission.
No big deal to me honestly. From the way I hear Transmission shifts if you’re not under load I’m not sure I’d want that on a gravel bike.
I got a response from SRAM, they checked it with stuff from their parts bin and it works! They don’t have any official manual for this as it is (according to them also) a very uncommon setup

@moukari You can definitely add an AXS Pod to a drop bar setup, device pairing wise. However, that ain’t fitting in the end of an aerobar extension… The diameter of the Pod portion that gets clamped is 22.2mm, the same as handlebars and extensions. The Pod infinity mount will clamp onto an extension, so I suppose you could hack it together, or get someone with 3D print abilities to design you a nice “bridge” mount for the Pod controller.

Yes I can’t put it in the end of the extension, but I could clamp it in the end of the aerobar where it is 22.2 mm. I try to figure out if that could be doable, it seems to be that the pod would be in a weird angle. I don’t know anyone here where I live who could 3D print a such mount. Wireless blips are on sale at r2-bike.de though…

Can anyone who has successfully installed transmission share what the shifting sounds like?
While it is perfect when in gear, when I shift there is a “clank” and sometimes gears are “crunchy” which is more noticeable when under load. A couple gears are smooth and quiet but most sound like shifting my mechanical under load.
Going to try to reinstall and see what I got wrong. But any feedback from those who have done it would be appreciated!
I do think it is louder … and slower than AXS Eagle.
I did a little video about it last year…

Thanks for sharing. Great video btw!
That’s exactly what mine sounds like… so that helps. I was taken back by the “clanks” and “crunching” when shifting (I cringe every time I hear it as those are not good sounds on my old drivetrain), but I guess that’s normal for transmission? AXS and mechanical are so much more quiet when shifting (not under load).
It does feel more “sturdy” when shifting under power going up a steep hill but not what I was expecting with the drivetrain noise.

I’m debating running my old XX cassette with my T-Type on my 2nd set of wheels. This reddit thread says it works fine as long as you add a 1.8mm spacer: Reddit - Dive into anything
I think only real risk would be longevity of chain, but I dunno man I could buy a lot of freaking chains for the $500+ that a 2nd T-Type cassette would cost me given this would be on my mostly spare wheel set.
Very interested in this as well…one of the major hangups that has prevented me from going to transmission is that I have 2 wheelsets with XX1/X01 cassettes and plenty of standard Eagle chains that would all go to waste if I couldn’t use them at all
I don’t mind spending $ on premium cycling gear when it makes sense, but the fully CNC’d SRAM eagle cassettes don’t hit my performance per $ ratio. The GX shifts the same at half the price with just a 1/4 lb weight penalty. Nothing wrong with going with the XX1/X01 if you are really concerned about weight, but GX can make a lot of sense (especially if talking about backup/training wheels).

Agreed on training wheels - I run GX chains and GX cassettes on training setups, just happen to have 2 “race” setups that seemed like they’d go to waste when switching to transmission.
GX is an amazing value for the performance/savings. You can also put an XX SL cage onto a GX transmission derailleur and be within 10g of a full XX SL derailleur but with the tucked away battery of the GX design. It’s only marginally cheaper than a normal XX SL derailleur but you’d have a spare cage as well

The Reddit post I linked is from a year ago and people have asked him for updates as recently as a few months ago and he said it’s still working great. N=1 but still
Yeah I hear you. I have a relatively new XX1 10-52 cassette that it pains me to not get use out of. I could sell it but not sure the used cassette market is particularly robust

I’m on Shimano, but aren’t the higher end SRAM chains much better bang for your buck in terms of longevity?
Both are very good, according to Zero Friction Cycling’s research:

That’s been my experience, so I splurge on the x01 chains rather than GX. GX for everything else. I’ve got some other X01 and XX1 stuff, but only because GX wasn’t around yet when purchased. As soon as they trickled down AXS to GX on the MTB and Rival on the road/gravel, I’m a Rival/GX guy all the way. Except chains and powermeter spiders.
Agree 100%. I have the XO T-type chain and cassette on my race wheels, T-type XO chain and GX cassette on training wheels, and T-type XO derailleur only because my GX derailleur failed and they replaced it with an XO because they didn’t have a GX. And Rival brifters.
But the text below the table says “Please note that GX level chains do not have HARDCHROME and wear VASTLY faster vs x01 & xx1 level chains.” (ZFC’s emphasis.)
Yeah I’m Ultegra/XT all the way, except chains.
fwiw, SRAM claims similar longevity marketing about the XX cassettes as well. For T-Type the XX cassette isn’t even lighter than the X0 as an example, it’s just that the XX and XX SL are made from “hardened tool steel” whereas the X0 and below aren’t. They claim the “hardened tool steel” will last much longer. Maybe less of an argument for XX SL since it has more aluminum cogs that will wear faster.
