I had a UNIVEGA fork that was just bent about 3° back. It really was not perceptible until I shoved a PVC pipe down the steerer tube to compare the fork arms alingnment. At replacement I was rewarded with not having to worry about the tip of my toes hitting the front wheel in a tight turn. I am still surprised at how only a 3° bend changed about 2cm of wheel clearance at the end of the fork.
