My motivation is to get rid of the original Sunrace hub and cassette and at the same time have narrower spaced gears.
The range of this 9-32t cassette is enough but the hub isn't reliable and the cassette is very difficult to find in spare parts.
I have two options, either go as with my Ti Birdy with a 3T 11s 9-32 cassette for XD/XDR hub and Shimano Ultegra or 105 derailleur that works very well but with the drawback that this cassette is not really available anymore.
The other option is to go with a full SRAM transmission using a 12s SRAM XDR cassette and SRAM road or gravel derailleur but there are only two cassette that give at least the same range I have, the 10-36t and the new XPLR 10-44t (there are also smaller range cassettes, the other SRAM wide range cassettes are MTB and not road cassettes). The 12s offer also closer spaced gears.
