& they designed the whole drivetrain to work together as a package. cranks/chainrings, both derailleurs, shifters, cassette, etc.

cassette cog ('speeds') count and clicks in the shifter have to be = and probably same as the rear derailleur brand/model

though often 105 and the ones above and below it in cost. work OK.

I would figure out what gear range you need , 1st... flatlander or mountain pass bagger.

Shimano's MTB will work when you max out past The road RD's capacities

Used often on tour bike builds..

It is, in the sense that if you want things to work properly, the whole drivetrain should be STI.
