   - **Coil Spring**: More consistent feel but heavier; good for downhill and aggressive riding.

3. **Damping System**: Look for adjustable dampers that allow you to fine-tune compression and rebound settings for optimal performance.

4. **Weight**: Lighter forks are easier to handle, especially for cross-country and trail riding, but durability is also important.

5. **Budget**: High-end forks come with advanced features and performance, but there are many great options available at lower price points for beginners and casual riders.
