We are reviving our Mystery Pic series! If you have any idea what this part is, please let us know in the comments section. This photo was submitted to us by Andy Wiedrich, Warranty Manager at University Bicycles in Boulder, Colorado, “We came across this guy, and have no idea what its for. FYI, A Ritchey Break Away Der hanger fits on this guy pretty darn close.”
