Can anyone confirm if a 9-speed SRAM X0 derailleur indexes correctly on a 10-speed cassette with a 10-speed SRAM X0 shifter? (and vice versa 10-speed derailleur indexes correctly on a 9-speed cassette with a 9-speed shifter)? They are both 1:1 Exact Actuation so I think they are cross-compatible. However, here suggests the derailleur shift ratio is different between the two.

I had this hairbrained idea that I might transplant the ratchet out of a smashed 10-speed X0 shifter into my 9-speed X0 shifter and then all my geared bikes can share wheels and cassettes because they'll all be 10-speed.

SRAM 1:1 and SRAM Exact Actuation are different. If one says 1:1 and the other says Exact, they probably won't work. In general SRAM 9 is incompatible with SRAM 10 (although there may be some odd bits that work together)

Edited out. Chatting shit

Yeah I feared that would be the case, so it won't be a direct swap.
