Abstract
A set of angle-adjusting head parts includes upper and lower head parts respectively mounted on top and bottom ends of a bicycle's head tube holding a front fork stem. The upper head parts include an upper bearing cup having an axially extending oval slot and two retaining surfaces arranged parallelly with the major axis of the oval slot at laterals, an upper bearing having an eccentric slot for receiving the front fork stem and an eccentric seat for engaging into the oval slot, and an adjusting washer mounted in the upper bearing cup and movable along the minor axis of the oval slot and having a circular opening for receiving the upper bearing. Rotating the upper bearing forces the eccentric seat to stop against the retaining surfaces and synchronously move the adjusting washer along the major axis of the oval slot, thereby biasing the angle of the front fork stem.
