I removed the fork from my old racer because I was hit by a car. When I'm trying to put the new fork on the frame, I get a gap where the top bearing is situated. What should I do? Could I just remove the bearing and put everything in place, or is that just too stupid?
It's possible that your head tube was ovalized when the wreck occured causing a gap. Also keep in mind that head tubes come in many sizes. Your fork may be the wrong size.
