I'm planning to build a new bike from scratch.
Part of that is buying a new frame, and possibly facing/reaming it. That's actually the part I'm scared of the most.
Fortunately, the brand I'm targeting, Surly, seems to do that in the factory. But as they state, there may be some paint left where it should not be:
Since Surly frames are faced prior to painting, it is possible to shave the paint off the head tube and BB shell ends with a carpet knife blade. This usually results in an acceptable result, saving you money, but we still recommend having it done the proper way to ensure longest life from your components.
So what is the "proper way" to remove the extra paint, if the frame is properly reamed/faced already?
Should I choose not to do it the proper way, which components are going to suffer? I suppose at least the headset and bottom bracket, but could the frame suffer as well?
