Abstract

A tool for fitting a bicycle to a cyclist includes first and second stirrup elements, a handle, and attachment elements attaching the first and second stirrup elements to each other and to the handle. The cyclist may be positioned with the cyclist'"'"'s back against a substantially flat surface and one leg extended away from the substantially flat surface and the foot of that leg engaging the first stirrup element and with the other leg bent and the foot of that leg engaging the second stirrup element. The cyclist may grasp the handle and pull the first stirrup element towards the cyclist'"'"'s head to a position in which the cyclist'"'"'s lumbo/sacral spine area moves away from the substantially flat surface.

Claims

1. A tool for fitting a bicycle to a cyclist, comprising:

a first stirrup element,

a second stirrup element,

a handle, and

attachment elements attaching the first and second stirrup elements to each other and to the handle,

whereby the cyclist may be positioned with the cyclist'"'"'s back against a substantially flat surface and one leg extended away from the substantially flat surface and the foot of that leg engaging the first stirrup element and with the other leg bent and the foot of that leg engaging the second stirrup element, and the cyclist may grasp the handle and pull the first stirrup element towards the cyclist'"'"'s head to a position in which the cyclist'"'"'s lumbo/sacral spine area moves away from the substantially flat surface.

2. A tool according to claim 1, wherein the first and second stirrup elements comprise first and second substantially rigid elements and the attachment elements comprise flexible elements that attach the first and second substantially rigid elements to each other.

3. A tool according to claim 2, wherein the first and second substantially rigid elements are tubular and the attachment elements are threaded through the tubular elements.

4. A tool according to claim 3, wherein the handle comprises a substantially rigid tubular element and an attachment element is threaded through the tubular handle element.

5. A tool according to claim 4, wherein the attachment elements comprise first and second lengths of flexible material threaded through the first and second tubular elements and forming respective loops, a third length of flexible material threaded through the tubular handle element and forming a third loop, the third loop being connected to the second loop, and a fourth length of flexible material attached at one end to the first loop and attached at an opposite end to the second and third loops.

6. A tool according to claim 5, wherein the fourth length of flexible material is adjustable in length.

7. A tool according to claim 5, wherein the first, second and third lengths of flexible material are of substantially equal respective lengths.

8. A tool according to claim 4, wherein the attachment elements comprise first and second portions of a length of flexible material threaded through the first and second tubular elements and forming respective loops, a third portion of said length of flexible material threaded through the tubular handle element and forming a third loop, the third loop being connected to the second loop, and a fourth portion of said length of flexible material attached at one end to the first loop and attached at an opposite end to the second and third loops.

9. A method of measuring hip flexion, including:

positioning oneself on a substantially flat surface,

engaging one'"'"'s right foot with a first stirrup element of a tool that also comprises a second stirrup element, a handle, and attachment elements attaching the first and second stirrup elements to each other and to the handle,

engaging one'"'"'s left foot with the second stirrup element,

positioning oneself so that one'"'"'s back is against the substantially flat surface, the right leg is substantially fully extended and is directed away from the substantially flat surface, the left leg is bent, and the left foot is adjacent the right calf,

grasping the handle and pulling the handle towards one'"'"'s chest while the right leg remains straight and the first stirrup element moves towards one'"'"'s head to a position in which one'"'"'s lumbo/sacral spine area moves away from the substantially flat surface, and

measuring the hip flexion.

10. A method of measuring hip flexion, including:

providing a tool that comprises a first stirrup element, a second stirrup element, a handle, and attachment elements attaching the first and second stirrup elements to each other and to the handle,

positioning the cyclist so that the cyclist'"'"'s back is against a substantially flat surface, one leg is extended away from the substantially flat surface, the foot of said one leg engages the first stirrup element, the other leg is bent, and the foot of said other leg engages the second stirrup element,

grasping the handle and pulling the handle towards the cyclist'"'"'s chest while said one leg remains straight and the first stirrup element moves towards the cyclist'"'"'s head to a position in which the cyclist'"'"'s lumbo/sacral spine area moves away from the substantially flat surface, and

measuring the cyclist'"'"'s hip flexion.

11. A method of fitting a bicycle to a cyclist, including:

providing a tool that comprises a first stirrup element, a second stirrup element, a handle, and attachment elements attaching the first and second stirrup elements to each other and to the handle,

positioning the cyclist so that the cyclist'"'"'s back is against a substantially flat surface, one leg is extended away from the substantially flat surface, the foot of said one leg engages the first stirrup element, the other leg is bent, and the foot of said other leg engages the second stirrup element,

grasping the handle and pulling the handle towards the cyclist'"'"'s chest while said one leg remains straight and the first stirrup element moves towards the cyclist'"'"'s head to a position in which the cyclist'"'"'s lumbo/sacral spine area moves away from the substantially flat surface,

measuring the cyclist'"'"'s hip flexion,

in the event that the cyclist'"'"'s hip flexion is in the range from about 130°

to about 140°

, adjusting the bicycle so that the top of the handlebars is level with the saddle,

in the event that the cyclist'"'"'s hip flexion is greater than about 140°

, adjusting the bicycle so that the top of the handlebars is higher than the saddle, and

in the event that the cyclist'"'"'s hip flexion is smaller than about 130°

, adjusting the bicycle so that the top of the handlebars is lower than the saddle.
