I have a Planet X carbon dirty harry with bonded in aluminum internal headset cups. With the spec'd FSA CF 40 headset, the crown of my 2014 Rock Shox SID rubs ever so slightly on the edge of the headtube. No headset company makes a taller race. FSA suggested having the the headtube faced. Planet X said this was OK but the local shop doesnt have the correct cutting tools. Is this something that can be safely done on a carbon frame?
