Crank Brothers is and always has been about marketing and image first, function and engineering second. ANyone thats spent any time on 50/50s can attest to that.
Saying that the setup is the reason so many posts are failing is the same as Apples "you are holding it wrong" excuse. If your product cannot deal with even slighly out of perfect setup, then its a failure on your part. You don't see other posts having similar issues and excuses.
Crank Bros needs to get their shit inline. That said, I'd imagine from the high sales figures they seem to have that its not a priority to fix their issues, as they sell product regardless.
