Swapped out my 11spd for this 12spd on my Kickr for my new DIS2 bike w/Dura-Ace$$$ cassette. Shifted perfectly and saved me half over a spare D-A cassette.

My road bike shipped with this 12 speed 11-30 cassette. I bought a second one for use with my Kickr Core smart trainer. It fit the trainer without issue.
