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.

Features:

Designed for internal frame routing
Cylindrical upper clamp nuts simplify installation
More vertical head clamp bolt angle increases clamping force
Dedicated cartridge architecture is reliable and smooth
Lightweight, rotating bottom actuator, reduced actuation force
Longer travel options
Alloy stanchion
Self-purging system
Compatible with all KS remotes
Remote sold separately
