pitted headset
hey guys, I have another question about my crappy beater of a bike. The headset is almost definitely pitted, but I'll try to describe my problem although I don't have a great grasp on the terminology. When I tighten the top cap on my headset (the frame is a '67 raleigh grand prix) down, the part that holds the ball bearings from the top, the wheel and handle bars wont move at all, so I have to loosen it and then it shakes up and down (like I can pull my fork/wheel down a few cm and push it back up). I realize this is bad. Despite this being bad, I've been riding it like this for like 6 months and haven't had any real issues with it other than constantly having to adjust it (tighten it a little so the fork doesnt shake too much/loosen it so that I can turn the wheel). Is there a cheap way that I can fix this? I'm willing to do the labor and have a fair amount of experiencing fixing the rest of the components on my bike. If not, how much should I pay for a headset etc?
