Abstract
A bicycle handlebar stem or stem/handlebar assembly has an inclined linear travel approximately 45 degrees from horizontal. This inclined path mimics a rider's natural arm inclination and pitching moment. 45 degrees is nearly ideal for most dropped bar road bicycles but different style bicycles may have an ideal angle between 30 and 60 degrees.
Claims12
A suspension handlebar assembly, comprising:
- a handlebar;
- a slider centered along the handlebar and extending below the handlebar;
- a stem having an upper surface, a first end, and a second end;
- a ramp at the first end of the stem below the upper surface and extending below the stem;
- and
- a connector at the second end of the stem,
- wherein the ramp is configured to engage the slider allowing for slideable movement between the ramp and the slider,
- wherein a spring is located in the ramp and configured to provide resistance to movement between the ramp and the slider to absorb impact energy;
- a damper to dissipate energy stored in the spring;
- a dial configured to adjust compression of the damper, the dial located at the top of the ramp;
- and
- an aperture located at a junction of the handlebar and the stem, the aperture configured to allow access to the dial.

A suspension handlebar assembly, comprising:
- a handlebar;
- a slider having a cross-sectional shape and centered along the handlebar and extending below the handlebar;
- a stem having an upper surface, a first end, and a second end;
- a ramp at the first end of the stem, the ramp having a top end and a bottom end and a cross-sectional shape sized smaller than said slider and slidable thereon, and the bottom end extending below the stem;
- a connector at the second end of the stem;
- and
- an aperture at a junction of the handlebar and stem, the aperture allowing access to the top of the ramp,
- wherein the ramp is configured to engage the slider allowing for slideable movement between the ramp and the slider;
- a spring and a damper located within the ramp and configured to absorb the impact of jolts;
- and
- a dial configured to adjust the stiffness of the damper.
