I'm usually the type to just do it but since I don't wan't to get into something needing special tools or skills or something I will just ask first
How do I remove the stem and lock nut so that I can get to and remove the cable guide? The cable guide is the worst part of the bike -by far- and needs to be sanded and "chromed." Just loosen the stem bolt and nut and take everything off? What about putting it back together? Seems very easy to do that but I don't know what little surprises lay in wait..
I don't know why the guide would rust while the headset itself is fine.
