The rear derailleur of the R9100 is a new designed for this a new outer casting is needed but this will be explained in another post. Today is the simple installation but first the weight: 160,5 grams.

As already said, the installation is quite simple. Look for the derailleur hanger on the back. When you got it screw on the derailleur with a torque of 8-10NM. The only thing which must kept in mind is the gap between the hanger-stop and the derailleur itself. The exact gap should be zero =D
