I have been trying to figure what to do about this bike with a bent steer tube. Before extracting it from the headset, it would turn smoothly when generally aimed straight but then would tighten up and have the most resistance turned 180 degrees. With the headset off, a straight edge revealed a slight bow in the steer tube with concavity toward the front while the fork also appears visually bent toward the front, apparently indicating in instance of trauma opposite that of a front-end collision.
