# Custom Gear Ratios

## Collisions

The 2nd Stage of the gearbox is 1.053", which is a 52T distance. This means any gear set that adds up to 52T will fit. The only limit to this is the Driving Gear, which cannot be larger than 24T, otherwise it will collide with the Kraken X60 Motors.

Going one size larger to a 26T Gear will cause the gear to collide with the Kraken X60 Motors.

The table below lists all possible gear sets for the 2nd Stage of the gearbox.

| Driving Gear | Driven Gear |
| ------------ | ----------- |
| 24           | 28          |
| 22           | 30          |
| 20           | 32          |
| 18           | 34          |

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wcproducts.com/welcome/gearboxes/wcp-ss-flipped-gearbox-single-speed-2-stages/general-info/ratio-options/custom-gear-ratios.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
