I have a Kona Rove ST, with a 40 teeth gear wheel and a 11-42 cassette. It's all SRAM. Here is the technical description.
It's ok for now, but I'm often using the smallest ratio (40x42) so I don't have any margin. Hence, I'd like to have a smaller gear ratio. To make it more complicated, I like my biggest ratio just fine, but I guess I'll have to compromise and lessen it.
But lowering my smaller ratio seems quite complicated and/or so expensive. So I thought I could just change the gear wheel for a smaller one. It seems straightforward to replace it with a 38 teeth one, but I'm not so sure for a 36 teeth one.
So my questions are: is it worth it to replace my gear wheel with a 38 or 36 one, and if so is it easy to do so? (especially for the 36 teeth) Or is there any other solution that would work?
