Introduction
Oakley's X-Metals have an extremely rigid frame made of a titanium alloy. In order for you to actually be able to wear them without stabbing your eyeballs out with the ear stems, they had to add some flex to the frame.
They did that by connecting nose bridge and orbitals with two press-fit pins that are cushioned by rubbers ("flex couplers"). These wear out over time letting those beautiful frames hang off of your face like toa drooping flower. Time to replace them.
The guide at hand can be seen as an addition to [http://www.linegear-japan.com/page/82] adding dis-and re-assemblyreassembly of Penny's spring hinge and some issues I encountered.
Who should attempt this repair: it is not super easy, but very doable if you have the right tools and like to do this kind of stuff. I specifically added mistakes I made so you don't have to repeat them. In the end, it worked out just fine.
X-Metals are expensive and rare, since they are not built anymore. If this is not for you, send them to a pro to have them tuned for you. There are very good people out there, that can even custom mod them for you, if you like.
