KS Ragei 2.0 Dropper Seat Post

The all-new KS Rage-i 2.0 evolves a proven platform with upgrades where it counts: on-bike tuning and optimized drop-to-length ratio, without losing its reputation for reliability and value.

Key Upgrades at a Glance:

• Air Pressure Tuning Via Schrader Valve → Adjustable Return Speed
• Threaded Seal Collar → Faster, Easier Servicing
• Self-Purging System → Eliminates Sponginess And Restores Full-Extension Support.
• Optimized Drop-To-Length Ratio → More Drop, Better Fit Across Frame Sizes

Designed to handle demanding trail conditions with smooth, reliable performance, the Rage-i now gives riders something it never had before: adjustability. Thanks to the addition of a Schrader valve under the head, the internal air pressure is no longer fixed. Riders can now fine-tune the return speed of the post, dialing in the feel to match their preferences and terrain. What was once a sealed, non-adjustable system is now a tunable component.

Serviceability also takes a big leap forward. The threaded seal collar replaces the one-piece chassis, making maintenance significantly faster and more straightforward.

Another key improvement is its self-purging system: If air and oil become mixed during use, causing a temporary soft or spongy feel at full extension, the post can restore itself through a simple self-purging process. By cycling the post through its travel a few times by hand, normal performance is quickly recovered. No tools, disassembly or service required.

But the real game changer lies in its reworked proportions. By combining a reduced mast length with a shorter actuator, the new Rage-i delivers more drop relative to its total length. This means:

Better fit in smaller or more constrained frames
More usable travel for a given insertion depth
Improved compatibility with modern bike geometries

In short, you get maximum drop efficiency without compromising fit.
