Hi All, new to Zwift.
Does it matter what ratio my cassette is i have on my trainer?
Not caring about the weight between 105/Ultegra/Dura Ace, but does the ratio of 11/25 - 11/32 make a difference to speed/watt etc?
If it does and there is a place to change it, can you point me to it? I don’t find the interface very easy to navigate.
