Will SRAM AXS work with a Shimano 12 speed cassette?

[@cel440]

Thanks for the vid although now a few months old. Pretty much have the same set up but bought a cheap 12spd cassette and chain. Shifts perfect and didn’t touch the micro adjust. Switching chain takes about 2 mins with the quick links. Got the chain for $25. Meant to add the 12spd parts are 105 - fine for trainer

[@JMCyclingVideos]

Glad to hear a Shimano chain helped out. That's excellent info to know.

[@Rudyjosephjr]

Running SRAM Force axs D2 12S on 12S ultegra cassette. Runs perfect. Smooth shifting. Problem? None so far after more than 1000miles.

[@JMCyclingVideos]

Good to hear! Indoors only or full-time indoors and outdoors?

[@Rudyjosephjr]

@@JMCyclingVideos full time outdoor.

[@affandieko9921]

What chain did you used?

[@JMCyclingVideos]

SRAM flat top 12 speed chain.

[@affandieko9921]

@@Rudyjosephjr you? What chain?

[@willhayes1976]

I run AXS 1x on my TT bike with an Ultegra cassette, but I also run 11sp pulleys and 12sp Shimano chain. I found the Shimano chain didn't get on well with the AXS pulleys, it lifts off due to the deep gulleys for the larger rollers.

[@JMCyclingVideos]

Good insight there. Since my bike is 100% AXS on the road, every other part is AXS including the chain. I originally thought that would cause additional wear on the cassette (or chain) but I really didn't observe that on the 11 speed cassette I used previously. Were you able to tune your AXS derailleur to the Shimano cassette? I'm tempted to try tuning it with the micro adjust, but I know it'll throw off the tuning on my AXS cassette on my wheel set.

[@willhayes1976]

@JM Cycling Videos it tuned in fine, I wonder if what you're hearing is partly the chain clattering through the cogs? It's worse on the pulleys as they're so small and have a lot of chain wrap, and you've got the opposite with the bigger rollers on the smaller gaps. I'd love to get hold of an AXS cassette to measure the spacing as I've heard it's not even across the range, there's only about .5mm difference in the total width though so I can't see it causing a huge issue over time

[@irondistance4313]

Thanks for making this I’m going to give it a try on my trainer as well. Roughly how many miles have you put on this setup?

[@JMCyclingVideos]

I’d say I have about 300-350 trainer miles on it. My trainer miles slow down in the summer as I do a lot more outside riding. No difference in noise and no noticeable wear.

[@nationsnumber1chump]

the axs rollers on the chain are a different size than a shimano chain so it will wear like twice as fast.

[@JMCyclingVideos]

Rollers are different. However, I ran an 11 speed cassette and really didn’t notice any abnormal wear after a year and a half,

[@nationsnumber1chump]

@@JMCyclingVideos you'd probably lose alot of watts though if you run hot wax

[@JMCyclingVideos]

Hot wax is legit. Definitely the way to go for max performance. But I’ve been there and done that and it’s just so time consuming. I’d love to have all the time in the world to hot wax all the time but unfortunately I don’t.

[@timesignal]

Thanks for doing this 😊

[@JMCyclingVideos]

Lots of people wanted it and I needed a new cassette for my trainer. So win win for all!

[@cosinus_square]

i'd be interested to see how a chinese 12 speed cassette works with axs

[@JMCyclingVideos]

This was also requested quite a lot, but I’m not sure how different in spacing and such that one of those would be, and I actually picked up this cassette for only $45 USD so, it was definitely cheap enough.

[@kenmilne8902]

Chinese 12 speed "Sunshine" cassette works fine with Force AXS derailleurs and chain

[@ata_473]

Hi, I was thinking of using a shimano cassette for indoor training as well. For context, I have the Rival eTap group-set. Have you noticed any extra wear on your drivetrain after months of usage?

[@JMCyclingVideos]

I haven't noticed extra wear. Even with the 11 speed cassette, I didn't notice anything. I think being indoors probably helps not being exposed to dirt and grime from outdoor riding.

[@stevefry4317]

What size cassette on your bike and what cassette on the trainers. I run Force 10-33 on the bike so thinking Shimano 11-34 on the trainer.

[@JMCyclingVideos]

I actually run a 10-28 on my bike and 11-34 on the trainer. But I used to interchange with a 10-33 so the chain is sized for that. I think that’s the best way to match the cassettes.

[@joefu1581]

Hey man. If I have a bike with Sram red 10-28 cassette and another one with force 10-33 cassette, what size Shimano cassette should I put on the trainer?

[@JMCyclingVideos]

As always, I have to say that neither SRAM nor Shimano would recommend this, but I would probably split the difference at 11-30 and call it good. Unless your bike with the 10-28 is at its limit on chain length. Then you might run into issues on that one.

[@arnoldmckz]

may i ask what type of chain are you using on this setup? im using the similar setup on my trainer with axs groupset, flattop chain and shimano cassette and the chain can't stay in the cassette(keep skipping)...thank you!

[@JMCyclingVideos]

I’m using the standard Force AXS flat top chain. No issues other than what you see in the video…

[@pieeredas]

Are u using shimano chain and cranks or sram

[@JMCyclingVideos]

All SRAM except cassette.

[@mickaelrogell7958]

Are you useing a flattop chain?

[@JMCyclingVideos]

Yep flattop. It’s all SRAM AXS except the cassette. Because I didn’t want to swap to an XDR freehub.

[@kamoteadventures23]

You should have tried using a shimano chain

[@JMCyclingVideos]

I certainly thought about it, but it kind of goes against the thought of making it easy to swap a SRAM bike onto a Shimano based trainer. I definitely wouldn’t have wanted to swap chains every time I put the bike on the trainer. It might’ve helped shifting though.

[@YellowfinCoachMatt]

so you are saying it does not work for you?

[@JMCyclingVideos]

Not saying it does or doesn’t work. Just demonstrating how it works on my particular set up so people can make their own determination. I personally wouldn’t run it on a wheelset outside, but I think it’s acceptable for use indoors on the trainer. Spacing is certainly a bit different
