I dont know if 12mm but it comes with 3 or 4 different sizes. My bike is a road with disc breaks and thru axle and the adapter came with it. But funny because I think somewhere it says it comes without or must be sold separately but I think they started sending it together because thru axle is now more or less standar.

It came with me, I just had to buy the cassette.

The adapter was included with my bike (without thru axle, bought Dec. 24)

Thank you for your answers. So I'll just order Rolle, at best it will be included - it's a shame that this is not clearly visible on sale.

Hello, no, not for me. Greetings
