Agree with that mate. I bought the 2011 version just when it came out with the plastic hose end….this inevitably snapped off so I bought the new metal clip, the 2012 version fixed this issue. Then about 3 months later, the post lost pressure…supposed to hold 250psi but would only hold about 100. Sent back to SRAM, and they replaced internals for me. Came back…all good….apart from the play which I am pretty sure was not there when I bought it. Now this may have been to do with the replacement internals but who knows. Anyway, back to SRAM again to investigate the play. As I said, prob about 1mm side to side and 1mm forward and back. You can see the flex in the rubber dust shield a tiny bit as you move the post. Post worked fine and air pressure held at 250psi. They sent it back to me saying no fault found and a tiny bit of play is necessary for the post to work. I am a chartered engineer so know all about tolerancing issues etc so can agree with them to a point. What seems weird is the inconsistency between different posts. I have physically seen some with absolutely zero play, and seen some a lot worse than mine.
I don’t really think SRAM were ready to release the post when they did – the R&D was not complete and they used us as the consumer as the test subjects….at 250 a pop back in 2011, this is not really on!
The 2013 version is better so I am told but to be honest when mine dies I will dump it and stick with my quick release.
