Claims2
A bicycle headset structure comprising:
- a tubular section having a first end with an upper end opening, and an axial passageway extending axially from the first end towards a second end of the tubular section, the second end of the tubular section including a set of first external threads;
- a top abutment section extending radially from the tubular section to form an abutment surface that faces in an axial direction towards the second end of the tubular section;
- and
- a steerer tube attachment section configured and arranged to adjustably couple the tubular section to a steerer tube such that selective adjustment of the steerer tube attachment section results in the abutment surface applying a downward force on a bicycle head tube to hold the steerer tube within the bicycle head tube, the steerer tube attachment section including a cylindrical section with a threaded bolt having a set of second threads that are threadedly engaged with the first external threads, and an abutment member with a radial width that is larger than a radial width of the tubular section.
