The Apex and the other SRAM road groups should be compatible with the XX group. The cable pull ratio is the same for the rear derailleurs. The cassette spacing is identical and is the same as Shimano's 10 speed spacing. You can mix and match SRAM 10 speed derailleurs and shifters, but you can't mix them with Shimano. The only Shimano part that is compatible would be the cassette. BTW, if anyone out there is running a SRAM road group and is troubled by the noisy drivetrain, switching to a Shimano Cassette really quiets everything down.
