I should have mentioned that you will need a medium cage RD (me bad, I forgot), you are correct but it's not just Apex, but any medium cage RD (that works with your shifters). My commuter has a medium cage Shimano (originally had a triple up front) so will work with the wide cassette (SRAM and Shimano are the same spacing). The Rival RD is also available in medium cage, and the 1070 'Rival' cassette can be had in an 11~32 as well. Heck, I even ran a 9 speed LX MTB long cage rear derailleur for a time on my commuter with Shimano road shifters 10 speed and the new SRAM cassettes will work with that RD too.
