# Dropper Post Compatibility Guide
## So, you're looking to upgrade your ride with a dropper post? Smart move! Whether you're getting sendy on a Nomad or crushing miles on a Stigmata, a dropper post is one of the best upgrades you can make for better control and more fun on the trails
### 1. Know Your Diameter
Frame seat tube diameters vary by model. It is essential to choose the correct dropper post diameter to match your frame.
| **Model** | **Seatpost Diameter** |
| --- | --- |
| **Stigmata, Highball** | **27.2 mm** |
| **Jackal** | **30.9 mm** |
| **All other models** (including V10, Bronson, Hightower, Nomad, etc.) | **31.6 mm** |
> **Note:** Seatpost diameters can vary by model year and version. Always verify your specific bike's requirements by checking the **[Santa Cruz Bike Archive](https://www.google.com/search?q=https://www.santacruzbicycles.com/archive/bikes)** or consulting your local dealer.
---
### 2. Minimum Insertion & Saddle Height
Every frame and dropper post has a **Minimum Insertion Mark**. For your safety and to prevent frame damage, this mark must *always* remain below the top of the seat tube.
- **Standard Minimum Insertion**: At least **80 mm (3.15 inches)** of the post must be inside the frame.
- **V10 Exception**: Due to its downhill nature, the V10 requires a minimum of **100 mm (3.93 inches)**.
- **Tire Clearance**: Ensure there is at least **6 mm of clearance** between your saddle and the rear tire when the suspension is fully bottomed out and the dropper is fully compressed.

### 3. Find Your Perfect Fit
Because every rider’s leg length and saddle height are unique, we’ve built a tool to take the guesswork out of "How much drop can I run?".
👉 **[Check out the Dropper Post Compatibility Tool](https://www.santacruzbicycles.com/pages/dropper-post-compatibility)**
This tool helps you determine the maximum and minimum dropper post length you can fit based on your specific bike model, frame size, and preferred saddle height.

**Need a hand with the install?** Dropper post cable routing can sometimes be a bit of a puzzle. If you're not comfortable routing the housing or setting the cable tension, reach out to your **[Authorized Santa Cruz Dealer](https://www.santacruzbicycles.com/dealers)** to get it dialed in perfectly.
