Bob makes an important point: If you don't know whether the dropouts are twisted (dropout alignment tool) or whether one blade is bent (fork bending tool), you might "fix" the wrong problem and end up with a twisted fork that while act oddly as it flexes.


I would suggest getting a better idea what's wrong before bending anything. Place straightedge or pipe on the blades near the crown and another near the dropouts. Are they parallel?
