Hi I have a question, I have 2 bikes and I want to use them both with my smart trainer wahoo.
One have a SRAM 12 sp. axs etap 48/35 the other one is Shimano 11 sp 50/34.
On the trainer now is installed SRAM 12 and with my Shimano bike a lot of pignons obviously doesn’t work.
So my question is, to have a compromise, and use both bike on trainer and using more pignons possible which cassette can i use? Shimano 11, SRAM 11 your suggestion please!
You are kind of mixing water and oil there. SRAM made their Flat Top chain along with the related cogs & chainrings unique. Apart from the width issue, they also use a larger diameter chain roller with matching pattern on the cog & chainring teeth.
It is a small difference, but a difference that is real. Some claim to mix the new SRAM with traditional gearing options, but it is not ideal. You will end up with a mismatch between them and personally, I’d never do it. I don’t like the risk of wear and damage to the parts that are not designed to work together.

They just aren’t compatible. Pick one bike to be the only one for the trainer or swap cassettes when you swap bikes. Those are the only good options
