Curious if this has happened to anyone else? I just completed a build on a leftover 2018 session from Trek done at my LBS. second day of riding and when I got to the top with the shuttle and roof the bike down I could hear rattling. Upon inspection of the bottom of the piggy back the bottom of it is askew and there is an o ring hanging out one side. Strange since I never thought during any of my riding wow that bottomed out. I could not even tell you what it was that caused it.
Happen to anyone else? Clear the rod that runs through the piggy back is bent.
