Have you ever damaged your disc brakes? Overheated them during a downhill or racked up a bill after missing the target with your bike cleaner?
Well, we’re guessing that no matter how much you ended up paying to get the things fixed, you probably still didn’t damage them as badly as this guy… who decided for one reason or another, to attack some disc brakes with an industrial lathe.
We can imagine it would’ve been a good stress reliever anyway.
