Hi and Merry Christmas.
My wife and I just purchased our first smart trainer and are setting up our Opus road bikes.
The Saris H3 didn’t come with a cassette so we purchased a separate Shimano 105 11 speed cassette. Pretty much matches our bike cassettes.
Tried both the medium and large through axel hub but are running into the same issue with both. On the small crank and largest cassette (lowest gear) , the rear derailleur rubs against the body of the trainer causing a chatter.
Thanks in advance.
