Cassette confusion for turbo trainer
Hi, hope someone can help here?
I'm currently using a Giant Contend SL2 Disc (2019) as my road bike. I've now purchased a Wahoo Kickr Core to use for indoors.
The Giant bike has a Shimano Tiagra 11-34 cassette but a 20 speed groupset (2x10).
I have bought a Shimano 105 R7000 11-34 to fit onto my KICKR however I have now realised that the bike cassette is actually a 10 speed.
Question is - should I return my new cassette and get a 10 speed for the turbo or is the 11 speed compatible with my bike?
Thanks in advance

Thanks for that, yeah the 11 part of the 11/34 threw me at first.
I've reordered and will send mine back.
An 11 speed cassette won't work happily on 10 speed Tiagra. Buy a 10 speed cassette.
If you can, for ease, I'd return it & get a 10 speed cassette.
