For many years there was 100% compatibility between SRAM and Shimano, but after Shimano when 10 speed with MTB (SRAM wasn't so big into road at that time) the compatibility split, with only cassettes (speed, not the fitting) now being the only real part in a groupset that is 100% interchangeable between SRAM and Shimano.
