# Custom Gear Ratios

## Possible Gear Ratios (Non-Flipped)

The table below lists all possible gear ratios and associated free speeds for the non-flipped configurations of the Swerve X.

The first row shows the possible gear sets for the first stage. The first column shows the possible gear sets for the second stage. All free speeds are in ft/s.

## Recommended Ratios

For the 2nd stage of the drive ratio, a 26T or smaller driven gear provides the required clearance for the module as it rotates. Listed in the table below are some recommended gear sets.

| Driving Gear Tooth Count | Driven Gear Tooth Count |
| ------------------------ | ----------------------- |
| 20                       | 26                      |
| 22                       | 24                      |
| 24                       | 22                      |

## Possible Issues

When creating custom overall drive ratios, the gear set for the 2nd stage must be carefully selected. The driven gear for this stage cannot exceed a 26T tooth count, otherwise the gear will collide with the module spacers and sensor shaft as the wheel module rotates.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.wcproducts.com/welcome/gearboxes/wcp-swerve-x/misc/other-configurations/ratio-options/custom-gear-ratios.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
