KS Kind Shock Rage Circuit Wireless 31.6 mm 120/380 mm

The KS Kind Shock Rage Circuit Wireless dropper seatpost proves that high-end electronics and uncompromising mechanical quality no longer have to be exclusive to the most expensive models. The KS brand took its years of know-how, precise internal craftsmanship, and legendary durability and put them into a model that makes "wireless freedom" accessible without any compromises on functionality. The seatpost completely eliminates the mess of internal routing and cables, bringing you not only perfectly clean bike lines, but above all machine-precise operation, lightning-fast installation, and care-free riding you can 100% rely on in any terrain.

This technological innovation in the wireless segment builds on years of experience and proven expertise from the premium LEV Circuit model. The result is uncompromising performance and maximum reliability transferred to a price point that makes wireless more accessible than ever. It is the ideal choice for riders seeking mechanical simplicity, a clean look, and great value.

Construction and Connection Transfer

The seatpost's design stems from the KS brand's extensive experience and utilizes a proprietary 2.4 GHz wireless connection. For you as a rider, this brings two major real-world advantages. The signal is digitally encrypted, which means it will never interfere with others in your riding group—even if your friends on the trail have the exact same seatpost or wireless drivetrain, your remote will always control only your seatpost.

The transmission is also lightning-fast, meaning the seatpost responds to the button press instantly and without any lag.

Wireless Simplicity Without Apps (Plug & Play)

A huge user advantage of the KS Rage Circuit system is its absolute independence from smartphones and mobile apps. Forget tedious registrations, firmware updates, or setting up accounts via Bluetooth before every ride. The seatpost and remote operate purely in "Plug & Play" mode—the components come pre-paired right from the factory. If you ever need to re-pair the system in the future, you can do it in seconds with a single button press directly on the seatpost body and remote. Simply mount the system mechanically to your bike, and you can hit the trail immediately without any software-related delays.

Advanced Internal Mechanics and Automatic Reset

A top-tier internal hydraulic cartridge ensures a smooth, velvety fluid, and precise stroke. A massive advantage of the Rage Circuit model is its integrated automatic reset functionality. This technology effectively solves the common issue of unwanted sagging or pulling air into the oil chamber, which typically happens with standard seatposts when accidentally pulling up on the saddle while the post is dropped. During normal use, the system automatically self-calibrates and maintains a solid position. Furthermore, the entire cartridge features a user-friendly design, meaning that after years of heavy operation, replacing it is quick and effortless.

Wireless System, Power, and Fast Charging

The seatpost is powered by a removable and rechargeable Li-Ion battery with a 400 mAh capacity, providing approximately 8 weeks of operation under normal use. If you drain the battery, simply unclip it and place it into the included USB charger—the battery charges to full capacity in just 1.5 to 2 hours.

The compact battery pack on the seatpost body can be removed without tools in just a few seconds and charged using the included docking station.

Handlebar Remote Control

The handlebar remote control is powered by a standard CR2032 battery with a lifespan of around 8 months. Thanks to this solution, worries about complex cable tension adjustments and mechanical wear of the control mechanism disappear, plus you can find a replacement battery virtually anywhere.

Uncompromising All-Weather Waterproofing

When mountain biking, the weather can change in a matter of minutes. But with the KS Rage Circuit, an unexpected downpour, deep puddles, or ubiquitous mud won't stop you. The entire system is engineered for maximum trail reliability, whether you ride technical singletrack or harsh enduro lines. Its durability under extreme conditions is proven by the IP67 certification—the seatpost is completely dust-tight and waterproof.

The electronic circuits and mechanical parts are perfectly sealed, enabling the system to survive temporary immersion in water without damage. After a demanding, muddy ride, you can wash the entire bike with a water stream without worries.

Compatibility and Construction

The KS Kind Shock Rage Circuit Wireless seatpost features a 31.6 mm diameter and an overall length of 380 mm. The saddle clamp is designed with versatility in mind and is fully compatible with both classic 7 mm round rails and 7x9 mm oval carbon rails. Included in the package is a complete set ready for immediate use, including the remote control, battery, and charger.
