Un autre article ICI, avec quelques commentaires intéressants en bas,
notamment ceci :
"For me a 2x10 is attractive because of how cheap it can be. I could get a 2x10 GRX setup with a 46/30 and 11-36. For me that would be perfect gearing, and it has 500% of range out of the box. The best part is that it would cost less to replace the cassette, chain, and the two chainrings than what a GX Eagle cassette alone costs.
If you're used to an 11spd 11-25, I think all wide range drivetrains will feel like they have big jumps between the gears. Of course some setups are worse than others, but you have to make the jumps bigger at the back and/or the front (or add a third chainring) to get more range, there is no getting around it. (You can increase the number of speeds, but that only goes so far.)"
