💡 What role does the internal nitrogen spring play in a drafting seat lifter?
- Nitrogen compression acts as a steady counterweight against your body mass.
- Manual leverage shifts the release ring to lower or raise the saddle smoothly.
- Steel guide rings prevent sideways sway while maintaining consistent tension.
- Seal rings block oil leaks to keep the pneumatic action handy all year.
