Sram/Shimano 12-speed cassette spacing compatibility?
Moderator: Moderator Team
Does anyone know if the recently announced Shimano 12-speed XTR cassettes will use the same spacing as the SRAM 12-speed? With 11-speed, you can mix and match with impunity - I have a couple of bikes using SRAM shifters/derailleurs and Shimano 11-speed cassettes.

That's a shame, it's always been good to know that they were the same, still it's probably choose enough to make it work?

Interesting thanks. XTR 12 speed has not been released yet right?
So XTR Shifter + RD with Sram cassette seems not to work properly because of the indexing on the shifter.
But it works with an Sram Shifter. Who would have thought that? But why even use a XTR RD in this case?
I don't get this whole "mixing parts up" thing anyway.
If you still what to use your shitty xD driver anyway, why not stick with Sram? Only because of the cheap, but maybe light and not reliable, rearhub you've got in your chinese wheelset?

Yeah, it does seem that Shimano RDs have a better reliability track record. I am pretty blown away by that second video though, as it implied that the cable pull ratio of the new XTR and Sram Eagle are the same, meaning a sort of return to cross-compatibility in one regard, even if we have lost cross compatibility with cassette spacing. That cassette incompatibility kind of sucks for anyone with a lot of wheelsets who might want to trade back and forth between bikes based on the tires/riding coditions, or if one wheel is waiting for repair and you want to keep the bike in service with a wheel swap.
Does anyone have cable pull ratio info yet? That cog spacing document was a sweet find, so something similar for the shift/derailleur system would be great.

Anyone knows the cog width of eagle and shimano 11s?
is anyone able to report any more real world testing on this. I've seen a couple of threads contradicting the videos in this thread (i.e. stating xtr 12sp RD adn shifter works with sram and sunrace 12sp cassettes). e.g. https://singletrackworld.com/forum/topi ... atibility/
I have a wheelset with an xd driver with little hope of a microspline freehub body in the near future (formula), plus some dt wheelsets I can put microspline on. Want to run xt or xtr shifters and RDs on the bike but have mutliple wheelsets in use.
i had several bikes previously with shimano RDs and shifters and sram cassettes in 11 speed with great shifting. Kind of also wondering if the shimano shifter in 11 speed mode would play with a sram 11 speed cassette or not, which might be a possible solution.
