KS (Kind Shock) stands for clever design, rugged durability and fluid seatpost performance you can trust. KS products are built for every rider who demands more comfort, more control and gear that works hard so you can pedal easy. Explore KS Saddles & Seat Posts and experience parts inspired by high-end tech that make every ride better.

Founded by Martin Hsu in southern Taiwan in the late 1990s, KS (short for Kind Shock) began life as part of Yen Yue Manufacturing making bicycle components like forks and stems. In 1998, Hsu turned inspiration from an office chair into the first modern dropper seat post prototype.

By 1999 KS released its first dropper post to market. Since then KS has driven forward innovation—building top-quality dropper, suspension and seat post systems, expanding material options, routing styles and drop lengths. That legacy still benefits riders today with reliable post-travel, excellent adjustment and component match for every bike style and budget.

• Pioneers of the dropper KS invented the dropper post in 1999, giving riders the ability to adjust saddle height while riding, which improves control on trails and steep descents.
• Superior materials and precision KS uses high-grade aluminium and hydraulic or air-sprung cartridges in its designs to ensure smooth action, minimal play and long life.
• Range of actuation styles You get cable actuation (both internal and external), mechanical remotes or wireless options so you can pick what suits your bike frame and riding style.
• Real-world durability Every KS post is tested in-factory for weight, return speed and ride tolerances, so your gear withstands rain, rocks and riding every week.
