I recently purchased a used Felt DA4 with SRAM Red components. The cassette is a 10 speed 11 26. I just picked up an Elite direct drive trainer on sale a Performance Bike that was going out of business but the only cassette I could find for the trainer was a Shimano 11 28. I put the bike on the trainer and it is riding really rough, like it can't find a gear. I know this is a novice question but I assume the reason for that is the fact that the cassettes are different and I would like to ask if that is a correct assumption on my part and I assume the fix for that would be to get another 11 26 for the trainer.
Thanks.
Thanks.
