Bicycle cassette with clamping connection
A bicycle cassette comprises a clampstyle connection for connecting the bicycle cassette to a bicycle hub driver body. The bicycle cassette is attached to a bicycle hub driver body by incorporating a clamp structure into one portion of the cassette, which then rigidly clamps onto the driver body of the bicycle hub. In addition, when combined with a bayonet style attachment structure between two parts of the cassette, it allows for the use of a smaller sprocket on one segment of the cassette. Specifically, it allows a small 9 or 10 tooth sprocket to overhang the cassette driver body on a bicycle hub, by attaching the small cog assembly to a larger cog assembly using a bayonet style attachment.
1. A bicycle cassette comprising:
a. a large sprocket sub-assembly comprising a clamping mechanism for attaching the large sprocket sub-assembly to a rear bicycle hub, wherein the large sprocket sub-assembly clamps to an outside radial profile of the rear bicycle hub; and
b. a small sprocket sub-assembly, wherein the small sprocket sub-assembly rotatably couples with and locks to the large sprocket sub-assembly after the large sprocket assembly is clamped to the rear bicycle hub to form the bicycle cassette.
2. The bicycle cassette of claim 1 , wherein the large sprocket sub-assembly clamps to the rear bicycle hub by tightening a clamp screw.
3. A bicycle cassette comprising:
a. a large sprocket sub-assembly comprising a clamping mechanism for attaching the large sprocket sub-assembly to a rear bicycle hub; and
b. a small sprocket sub-assembly, wherein the small sprocket sub-assembly rotatably couples with and locks to the large sprocket sub-assembly after the large sprocket assembly is clamped to the rear bicycle hub to form the bicycle cassette, wherein the small sprocket sub-assembly is coupled to the large sprocket assembly using a locking bayonet style attachment.
4. The bicycle cassette of claim 1 , wherein the small sprocket sub-assembly comprises a 9 tooth sprocket.
5. The bicycle cassette of claim 1 , wherein the small sprocket sub-assembly comprises a 10 tooth sprocket.
6. The bicycle cassette of claim 1 , wherein the large sprocket sub-assembly comprises a 46 tooth sprocket.
7. The bicycle cassette of claim 1 , wherein the large sprocket sub-assembly comprises a 50 tooth sprocket.
8. The bicycle cassette of claim 1 , wherein the large sprocket sub-assembly and the small sprocket assembly are manufactured from different materials.
9. The bicycle cassette of claim 1 , wherein the small sprocket sub-assembly overhangs a cassette driver body of the bicycle hub in an assembled configuration.
10. The bicycle cassette of claim 1 , wherein the small sprocket sub-assembly comprises a bushing, which radially supports said small sprocket sub-assembly on the cassette driver body of the bicycle hub in the assembled configuration.
11. A bicycle cassette and hub system comprising;
a. a rear bicycle hub;
b. a hub driver assembly coupled to the rear bicycle hub; and
c. a cassette assembly clamped to the hub driver assembly, the cassette assembly comprising:
i. a large sprocket sub-assembly comprising a clamping mechanism for clamping the large sprocket sub-assembly to the hub driver assembly, wherein the large sprocket sub-assembly clamps to an outside radial profile of the rear bicycle hub; and
ii. a small sprocket sub-assembly, wherein the small sprocket sub-assembly rotatably couples with and locks to the large sprocket sub-assembly after the large sprocket assembly is clamped to the rear bicycle hub to form the bicycle cassette assembly.
12. The bicycle cassette and hub system of claim 11 , wherein the large sprocket sub-assembly clamps to the hub driver assembly by tightening a clamp screw.
13. A bicycle cassette and hub system comprising;
a. a rear bicycle hub;
b. a hub driver assembly coupled to the rear bicycle hub; and
c. a cassette assembly clamped to the hub driver assembly, the cassette assembly comprising:
i. a large sprocket sub-assembly comprising a clamping mechanism for clamping the large sprocket sub-assembly to the hub driver assembly; and
ii. a small sprocket sub-assembly, wherein the small sprocket sub-assembly rotatably couples with and locks to the large sprocket sub-assembly after the large sprocket assembly is clamped to the rear bicycle hub to form the bicycle cassette assembly, wherein the small sprocket sub-assembly is coupled to the large sprocket sub-assembly using a locking bayonet style attachment.
14. The bicycle cassette and hub system of claim 11 , wherein the small sprocket sub-assembly comprises a 9 tooth sprocket.
15. The bicycle cassette and hub system of claim 11 , wherein the small sprocket sub-assembly comprises a 10 tooth sprocket.
