Bicycle handlebar, stem, and fork arrangement
View Patent ↗A bicycle handlebar/stem/steering tube assembly has a handle bar diameter and a steering tube diameter there-within. One or both of the steering tube and the handlebar includes one of a depression, a diameter-reduction, and a through-hole configured to mate rigidly against the other of the steering tube and the handlebar and be affixed thereto by the stem at a handlebar/steering tube interface such that a stem offset is created of a dimension that is less than either the handlebar diameter and the steering tube diameter at the handlebar/steering tube interface.
1. An assembly of a bicycle handle bar, stem, and steering tube, having a handle bar diameter and a steering tube diameter there-within; wherein one of the steering tube and the handlebar comprises one of a depression, a diameter-reduction, and a through-hole configured to mate rigidly against another of the steering tube and the handlebar, and be affixed thereto by the stem at an interface of the handlebar and the steering tube, wherein the one of a depression, a diameter reduction, and a through-hole enables a stem offset that is of a dimension that is less than the handlebar diameter at the handlebar/steering tube interface, and less than the steering tube diameter at the handlebar/steering tube interface.
2. The assembly of claim 1 wherein the one of the steering tube and the handlebar is the steering tube.
3. The assembly of claim 2 wherein the one of a depression, a diameter-reduction, and a through-hole is a depression.
4. The assembly of claim 2 wherein the one of a depression, a diameter-reduction, and a through-hole is a circular through-hole.
5. The assembly of claim 1 wherein the one of the steering tube and the handlebar is the handlebar.
6. The assembly of claim 5 wherein the one of a depression, a diameter-reduction, and a through-hole is a depression.
7. The assembly of claim 5 wherein the one of a depression, a diameter-reduction, and a through-hole is a circular through-hole.
8. The assembly of claim 1 wherein the one of the steering tube and the handlebar is both.
9. The assembly of claim 8 wherein the one of a depression, a diameter-reduction, and a through-hole is a depression.
10. A bicycle handlebar having a handle bar diameter and comprising one of a depression, a diameter-reduction, and a through-hole configured to mate rigidly against a bicycle steering tube having a steering tube diameter; and to be affixed thereto by a stem at an interface of the handlebar and the steering tube such that the one of a depression, a diameter-reduction, and a through-hole enables a stem offset of a dimension that is less than either the handlebar diameter and the steering tube diameter at the interface.
11. The handlebar of claim 10 wherein the one of a depression, a diameter-reduction, and a through-hole is a depression.
12. The handlebar of claim 10 wherein the one of a depression, a diameter-reduction, and a through-hole is a circular through hole.
13. The handlebar of claim 12 wherein the circular through hole is a vertical circular through-hole.
14. A bicycle steering tube having a steering tube diameter and comprising one of a depression, a diameter-reduction, and a through-hole configured to mate rigidly against a handlebar having a handlebar diameter; and to be affixed thereto by the stem at an interface of the handlebar and the steering tube such that the one of a depression, a diameter-reduction, and a through-hole enables a stem offset of a dimension that is less than either the handlebar diameter and the steering tube diameter at the interface.
15. The steering tube of claim 14 wherein the one of a depression, a diameter-reduction, and a through-hole is a depression.
16. The steering tube of claim 14 wherein the one of a depression, a diameter-reduction, and a through-hole is a circular through hole.
17. The steering tube of claim 16 wherein the circular through hole is a horizontal circular through-hole.
