Sram shifters with shimano derailleurs (road)

[montage]

Are these compatible?
I mean, sram and shimano cassettes are interchangeable are they not? Therefore the derailleurs must be compatible with each of the cassettes, which means the shifters must all pull the derailleur the same distance to make the shifts...
...so why wouldnt sram shifters and shimano derailleurs be interchangeable?

(thinking of replacing my ultegra shifters for sram rival/force shifters)

They're not. The lever pull different amount of cable, and the parralelograms are different in the mechs. It won't work.

Agree with young un. Sram pull more cable than anyone else.
This is an excellent comparison discussion:

The only thing I know that works is the Attack, Centera and the MRX but there all MTB. as far as I know there is no Road! but I know some one that will know and Ill be seeing them in a week so Ill ask for you.

Whilst the data in the tables shows SRAM 1.0 is certainly different, I thought some SRAM models were compatible with Shimano? Or is it just the cassette spacing/mounting where SRAM is Shimano compatible?

I think it's just cassette spacing. You usually get Sram mechs AND shifters, but Shimano cranks and casette (or other makes of crank).

Cassettes and chains are both interchangeable

Sram shifters will only work with Sram rear mechs
Shimano shifters will only work with Shimano rear mechs

Front mechs will work with both Shimano and Sram

edit: thats for both road and MTB, although there are a couple of sram flat bar MTB shifters that work with Shimano. rocket and attack iirc
