About ExaForm

ExaForm is a specialist dropper post manufacturer producing reliable, performance-focused seatposts for mountain bikers at all levels. Their range covers a variety of post diameters, travel lengths, and actuation styles to suit a wide range of frames and rider preferences. At Swinnerton Cycles, we stock ExaForm dropper posts as a quality upgrade option for riders looking to improve their trail performance without overspending.

Consistent Actuation, Every Time

ExaForm dropper posts are engineered for smooth, consistent actuation across a wide range of temperatures and conditions. The internal cartridge design minimises play and ensures reliable return to full extension, giving riders the confidence to focus on the trail rather than their equipment.

JAGi, Jag & 900i — Which Post is Right for You?

The ExaForm JAGi is the top-spec model, offering infinite travel adjustment for precise saddle height control on the move. The Jag provides reliable three-position actuation in a robust, trail-ready package. The 900i is an excellent entry-level option for riders making their first dropper upgrade, delivering the core benefits of a dropper post at an accessible price point.

Choosing the Right ExaForm Dropper

The correct dropper post depends on your frame's seat tube diameter (typically 30.9mm, 31.6mm, or 34.9mm), the available insertion length inside your seat tube, and your preferred cable or remote routing. Travel length should be chosen based on your riding style and the minimum insertion depth your frame allows. If you need help selecting the right ExaForm post for your bike, the Swinnerton Cycles team is happy to advise.
