Hey group.
Im moving to the sram 13speed 1by this season and am currently using the ZwiftCog on my trainer, through the SystemX platform.
Id like to run more non-ERG training in the future.
Do i have to put a 13speed cassette on the trainer? Or could I get away with a cheaper 12speed?
Thanks for the help clarifying this.
I can’t speak to 13 vs 12 speed but I have ran an 8 speed cassette for both my 8 speed Claris trainer bike and my wife’s 9 speed sora. Her bike worked for the most part. There were a couple gears where the chain would be loud on the cassette or occasionally want to jump but nothing horrible. If you stick to the smoother gears you might be okay but there is a chance for accelerated chain or cassette wear.
