stuck or corroded threadless fork

many will want to just drive the steerer tube straight down but this is wrong or much harder than attacking it differently. if you try to drive it straight down you are breaking the bond of everything at once. there is lots of surface area. driving it down also wedges the split wedge tighter and grips the tube. very hard to do. knock off 1 piece at a time. spin each spacer to break the bond. sometimes i use some rubber around the pliers but if its stuck good go for the teeth. after one is spun drive it up with a screw driver or putty knife. now sand the corrosion off the tube. repeat until you win
