The KS Rage-iS is designed for mountain, gravel, and touring riders who demand both adjustable saddle height and increased vibration damping in a single component. By combining dropper functionality with air-sprung suspension, it provides a smoother ride on technical terrain, though riders should note that the necessary remote control lever must be purchased separately.

No, all KS remotes for the Rage-iS are sold separately.
Yes, you can fine-tune the plushness of the ride by adding or removing air pressure using a standard Schrader valve shock pump.
This post is designed specifically for internal frame routing.
Use the included O-ring on the stanchion; it will slide to show you exactly how much the post is compressing under your weight.
While it is designed for mountain, gravel, and touring bikes, it is compatible with any frame that supports internal routing and has a 30.9mm seat tube diameter.
Check the air pressure in the suspension chamber and ensure the cable housing is not kinked or contaminated with dirt.
Ensure the micro-adjustable clamp bolts are tightened to the manufacturer's recommended torque specification.
Verify the cable routing for sharp bends and lubricate the cable internally; adjust cable tension at the remote.
Installation of the Rage-iS requires a frame compatible with internal cable routing. Start by inserting the post to your desired height, ensuring the seat tube is clean and free of debris. Use a standard high-pressure shock pump to adjust the air spring pressure via the Schrader valve located under the saddle clamp; start at the manufacturer's recommended baseline for your body weight. Maintenance includes cleaning the stanchion after every ride and applying a light coat of suspension-specific lubricant. Periodically check the cable tension for the remote actuator and inspect the seat clamp bolts to ensure they remain within the specified torque values.
