Rock Shox Recon does not "completely" lock
RockShox FAQ FRONT SUSPENSION Remotes/Lock Outs:


  Why Isn’t The Lockout Function Completely Locked, Instead, There’s A 
  Bit Of Travel?
  Please know the lockout setting on most RockShox forks is not a “hard 
  lockout”- meaning you will have about an inch of movement when the
  fork is the locked mode. We call this feature Small Bump Compliance, 
  and the intention is that the wheel will continue to track over 
  ground with control, even in the locked setting.
