Top tier performance at a never before seen price point from KS. The longevity, smoothness, and weight of the Rage, give posts 3x the price something to worry about. Who's this for: Riders wanting a truly excellent dropper at a more affordable price than ever. Clamp options: Only available in the two leading size standards, 30.9mm and 31.6mm diameter. Spring and system: The Rage uses an adjustable air spring, with an open bath hydraulic cartridge. An all new keyway system locks the post in place. A one piece, machined outer mast with an integrated seal head keeps simplicity at a maximum, and fiddly parts to a minimum. Infinite vs multiple positions: The Rage is infinitely adjustable within it's travel range, allowing for the perfect position for whatever situation arises. Remote: These posts do not come with a lever so you can pair it up with an option of your choice. Includes cable / housing: Yup, this kit includes the necessary inner and outer cables to make the seatpost operational. Routing: Internally routed here. This is a front feeding design, so the cable requires a barrel nut to click into the posts poly-carbonate actuator. This means it is compatible with any dropper lever on the market. Weight: Weight ranging from 448g to 549g, travel length dependent. Warranty: 2 year warranty period, so long as regular servicing is maintained. KS recommend a simple seal service every 3 months. Pros: Legitimately fantastic performance, minimal cost, very simple. Cons: Not particularly fancy, with no special features.
