At this point, you're probably looking at 10, 11, and 12 speed cassettes. Most will likely be Sram/Shimano - maybe a handful of Campy. And I'd guess you're looking at 50/50 disc/rim brakes. All the 10-spd stuff is likely to be rim. All 12-spd stuff will be disc and the 11 will be half and half.
So if you really wanted to try sorting it, I'd suggest these categories:
- Campy
- 10 spd Sram/Shimano
- 11 spd Sram/Shimano Rim
- 11 spd Sram Shimano disc
- 12 spd Disc
That's best sorting outcome I can think of that doesn't get too complicated/granular. Others may have different thoughts.
