Pardon the novice question but I am not an expert on this.
I have a 3T Strada 1X with the SRAM factory 11 speed cassette (11-32) as my primary road bike. On my direct drive trainer I have a Shimano 105 11 speed cassette (think it is an 11-30 but not sure). If I wanted to use my Strada on the trainer do I need to switch the cassette? Or can I use the same cassette? Would you recommend I switch the cassette? 95% of my trainer time are TR workouts in ERG mode. The other 5% would be free riding in Zwift.
Any help would be greatly appreciated. Thanks.
