I have an S-Works Roubaix that is 2 years old with about 9,000 miles on it. I have never touched the derailleur hanger.
Should I replace the hanger as a preventative maintenance matter?
It is recommended to remove it once in a while from the frame to check the interface between hanger and frame?
What torque is usually used on the single screw that holds the hanger to the frame/drop out?
