Ergonomic bicycle handlebar and cycling systems
An ergonomic and aerodynamic bicycle handlebar system having appropriate sweep angles and slope angles, embodiments of which can vary both for the type of application and the width of the bar, provides improved energy efficiency, comfort and increased center of gravity control. Flare angle and drop angle can also be adjusted for particular applications. The handlebar may be made of carbon fiber or other suitable materials. Various alternative embodiments are disclosed for drop handlebars and mountain bike handlebars.
1. A bicycle handlebar comprising:
a stem mount portion substantially bisected by a sagittal plane, the stem portion being fixedly disposed between symmetrical left and right top portions wherein each of the left and right top portions comprises an inner portion and a central grip portion,
the left inner portion extending forward, upward, and to the left relative to the stem mount portion and having an upper end,
the right inner portion extending forward, upward, and to the right relative to the stem clamp area and having an upper end,
the left central grip portion formed integrally with and connected to the left inner portion at the left inner portion's upper end and extending to the left therefrom with an acute downward slope angle relative to the sagittal plane and an acute sweep angle relative to a plane orthogonal to the sagittal plane,
the right central grip portion formed integrally with and connected to the right inner portion at the right inner portion's upper end and extending to the right therefrom with an acute downward slope angle and an acute backward sweep angle, wherein a cavity is formed between the left and right inner portions and opposing thumb indexes are formed on the left and right inner portions within the cavity, and
a frontal bar extending between the left central grip portion and the right central grip portion and enclosing the cavity therebetween.
2. The handlebar of claim 1 wherein the opposing thumb indices are formed substantially at each of the junction of the left inner portion with the left central grip portion and the junction right inner portion with the right central grip portion.
3. The handlebar of claim 1 wherein the opposing thumb indices extend down an inner sidewall of each of the left inner portion and right inner portion.
4. The handlebar of claim 1 having a mount formed centrally in the frontal bar, the mount configured to hold one or more cycling accessories.
5. A bicycle handlebar comprising:
a stem mount portion substantially bisected by a sagittal plane, the stem portion being fixedly disposed between symmetrical left and right top portions wherein each of the left and right top portions comprises an inner portion and a central grip portion,
the left inner portion extending forward, upward, and to the left relative to the stem mount portion and having an upper end,
the right inner portion extending forward, upward, and to the right relative to the stem clamp area and having an upper end,
the left central grip portion formed integrally with and connected to the left inner portion at the left inner portion's upper end and extending to the left therefrom with an acute downward slope angle relative to the sagittal plane and an acute sweep angle relative to a plane orthogonal to the sagittal plane,
the right central grip portion formed integrally with and connected to the right inner portion at the right inner portion's upper end and extending to the right therefrom with an acute downward slope angle and an acute backward sweep angle, wherein a cavity is formed between the left and right inner portions and opposing thumb indexes are formed on the left and right inner portions nearest the stem clamp area, and
a frontal bar extending between the left inner portion and the right inner portion and enclosing the cavity therebetween.
6. The handlebar of claim 5 having a mount formed centrally in the frontal bar.
