Had a look at headset on the winter bike as it was getting a bit rough and it is goosed so I am going to have to replace it. I have a replacement heatset sitting doing nothing in my garage and thought I'll have a go replacing it myself. However the outer parts are fused into the frame top and bottom. Mentioned it to guy in LBS who said that I might be able to use cup removing tools which I don't have or failing that knock them out with a chisel. I am wondering if anyone here has tried this and has any tips?
