​KS Rage-i 2.0 telescopic seatpost: Greater travel and easier to maintain than ever before

The Rage-i series has been one of the classic mechanical Vario seatposts in the Kind Shock range for years and is aimed primarily at trail, all-mountain and enduro riders looking for a robust, relatively simple solution.

In the market, the Rage-i has traditionally been positioned in the mid-price range and is regarded as a good choice for riders looking for solid value for money and tried-and-tested technology. The series is characterised by its focus on reliability and straightforward performance.

​For a long time, the Rage-i was designed to be rather conservative: it offered few adjustment options, but was solid and functional. This is precisely where the new Rage-i 2.0 comes in: without straying from the basic concept, it expands the range with features such as adjustability, improved serviceability and modern proportions.

Rage-i 2.0 now features adjustable air pressure

The biggest change concerns the adjustability of the support. Whilst the previous model was designed as a closed system, the Rage-i 2.0 can now be customised to suit individual needs.

Using a Schrader valve located beneath the head, the rider can adjust the internal air pressure – and thus directly influence the rebound speed. This transforms what was previously a fixed-setting mechanism into an adjustable component that can be better adapted to different preferences and riding conditions.

Easier maintenance and self-venting

KS is also stepping up its game when it comes to service. The new threaded seal collar replaces the previous one-piece housing. This makes the strut much easier to access.

A common problem with dropper posts is a spongy feel when fully extended. KS addresses this issue with a self-purging system. If air and oil mix inside the seatpost, it can self-regenerate: simply cycling through the full stroke a few times is enough to restore its original function, without the need for tools or dismantling.

Optimised stroke-to-length ratio

The revised geometry of the strut is expected to deliver a noticeable improvement. A shorter overall height at the head and a more compact actuator significantly improve the ratio of stroke to overall length.

This has specific implications:

• more usable stroke with the same insertion depth
• better integration into compact or modern frames
• greater compatibility with current geometries

Compared with its predecessor, the maximum stroke has increased to 210 mm, whilst the design is now more compact.

A tried-and-tested foundation, but modernised

Despite these innovations, the Rage-i 2.0 remains a classic, mechanical Vario seatpost with internally routed controls. The system utilises a cartridge design with a combined air/oil system, which is intended to ensure smooth operation.

Conclusion from the editor’s perspective

KS has fine-tuned the right settings on the Rage-i 2.0. In particular, the new air pressure adjustment option adds real value to everyday use and clearly sets the suspension apart from its predecessor. Added to this are practical solutions such as simplified maintenance and the self-bleeding system, which tackle typical problems encountered in everyday cycling.

The biggest advantage, however, remains its more compact design with greater travel. With modern trail and enduro bikes in particular, it is often the installation length that determines whether a seatpost will fit or not – and this is where the Rage-i 2.0 has a real advantage.
