Abstract

A user accessible shock travel spacer assembly is disclosed herein. The system is used on a shock assembly having a shaft with an initial predefined stroke length. A retaining cap having a retaining cap thickness and a retaining cap opening therethrough. The retaining cap opening having a diameter that is larger than an outer diameter (OD) of a shaft of a shock assembly. At least one fastener to fasten the retaining cap with a portion of the shock assembly about the shaft, such that the retaining cap reduces a stroke length of the shaft of the shock assembly by the retaining cap thickness.

Claims (42)

1. A travel spacer assembly comprising:

a retaining cap comprising:

a retaining cap thickness; and

a retaining cap opening therethrough, said retaining cap opening having a diameter (D) that is larger than an outer diameter (OD) of a shaft of a shock assembly;

at least one fastener to fasten said retaining cap with a portion of said shock assembly about said shaft, such that said retaining cap reduces a stroke length of said shaft of said shock assembly by said retaining cap thickness;

at least one travel spacer comprising:

a travel spacer thickness;

a travel spacer opening therethrough, said travel spacer opening having a diameter that is larger than said OD of said shaft of said shock assembly; and

at least two separable pieces, such that said travel spacer is installed about said shaft of said shock assembly to form said at least one travel spacer, such that said travel spacer is configured to be installed about said shaft of said shock assembly to form said travel spacer without requiring removal of said shaft from said shock assembly, said travel spacer reducing said stroke length of said shaft of said shock assembly by said travel spacer thickness to enable an end user to customize said stroke length for said shock assembly;

an air sleeve of said shock assembly to form an air chamber;

a piston coupled with said shaft;

said piston dividing said air chamber into a positive air chamber side and a negative air chamber side; and

said at least one travel spacer coupled to said negative air chamber side of said shaft.

2. The travel spacer assembly of claim 1 , further comprising:

at least one attachment hole in said retaining cap; and

said at least one fastener inserted into said attachment hole to couple said retaining cap with said portion of said shock assembly.

3. The travel spacer assembly of claim 1 , further comprising:

an OD of said retaining cap, said OD of said retaining cap smaller than an inner diameter (ID) of a helical spring of said shock assembly.

4. The travel spacer assembly of claim 1 , further comprising:

an OD of said retaining cap, said OD of said retaining cap smaller than an inner diameter (ID) of an air sleeve of said shock assembly.

5. The travel spacer assembly of claim 1 , further comprising:

a geometric shape of said retaining cap selectively configured to displace a volume of air wherein, said volume of air is equal to π/4 times the square of said diameter (D),

said displacement of said volume of air modifying a performance characteristic of said shock assembly in addition to reducing said stroke length of said shaft.

6. The assembly of claim 1 , further comprising:

a geometric shape of said retaining cap selectively configured to displace volume of air wherein, said volume of air is less than π/4 times the square of said diameter (D),

said displacement of said volume of air modifying a performance characteristic of said shock assembly in addition to reducing said stroke length of said shaft.

7. The travel spacer assembly of claim 1 further comprising:

a geometry of said at least one travel spacer based on an amount of air displacement of said at least one travel spacer, wherein said amount of said air displacement modifies a performance characteristic of said shock assembly in addition to reducing said stroke length of said shaft.

8. The travel spacer assembly of claim 1 further comprising:

said at least one fastener to fasten said retaining cap and said at least one travel spacer with said portion of said shock assembly about said shaft.

9. The travel spacer assembly of claim 1 further comprising:

a travel spacer retainer to retain said at least one travel spacer with said shaft of said shock assembly, such that said at least one travel spacer does not need an attachment hole therethrough, said travel spacer retainer selected from a group consisting of: a clip, a hook, and a snap.

10. The travel spacer assembly of claim 1 , further comprising:

an air sleeve of said shock assembly to form an air chamber;

a piston coupled with said shaft;

said piston dividing said air chamber into a positive air chamber side and a negative air chamber side; and

said at least one travel spacer coupled to said positive air chamber side of said shaft.

11. The travel spacer assembly of claim 1 , further comprising:

an OD of said at least one travel spacer, said OD of said at least one travel spacer smaller than an inner diameter (ID) of an air sleeve of said shock assembly.

12. The travel spacer assembly of claim 1 , further comprising:

an OD of said retaining cap, said OD of said retaining cap smaller than an inner diameter (ID) of a helical spring of said shock assembly; and

an OD of said at least one travel spacer, said OD of said at least one travel spacer smaller than said ID of said helical spring of said shock assembly.
