Both shifters and derailleur are 10 speed. Don't ask me the in and outs but i have read a number of sources that validate compatibility and a number that call it out also have read heard things about alternate wiring within components for comparability which may be the case here because as I mentioned there are no extra/redundant clicks and all gears shift smoothly
