A wireless telescopic seatpost designed for modern mountain biking

The SEEKRUN S8 Bluetooth was developed to simplify mountain biking while maintaining a high level of reliability. No more cables, no more housing, no more mechanical stress: the bike gains in aesthetics, ease of maintenance, and user comfort.

Its ultra-fast 0.03-second response time allows for instant saddle adjustment, ensuring intuitive and safe use even in the heat of the action. This responsiveness provides a real boost in confidence on technical and rugged terrain.

Comfort, control and safety on all terrains

On climbs, the saddle immediately returns to its ideal height to optimize pedaling efficiency. On descents or technical sections, it lowers instantly to offer greater freedom of movement and improved stability.

This adaptability significantly improves the rider's handling, comfort and confidence, especially on challenging trails, fast descents and technical areas.

Quick installation and sleek design

One of the great advantages of the SEEKRUN S8 lies in its ease of installation. Thanks to its wireless operation, no complex disassembly is required to integrate cables into the frame.

The result: quick assembly, significant time savings and a visually cleaner and more modern bike.

All-terrain reliability and robust design

Made from high-strength aluminum alloy, the SEEKRUN S8 is built to last. Its wear-resistant coating with premium lubrication ensures excellent operating smoothness and high wear resistance.

Its IP67 certification ensures optimal protection against dust, mud and rain, so you can drive with complete peace of mind whatever the weather conditions.

With an advertised endurance of up to 9,000 uphill and downhill cycles, it perfectly meets the demands of regular and intensive mountain biking.
