Reduce Riding Pain & Increase Comfort: Absorb bumps, dips, and drops. This will soften your ride and make biking more comfortable and enjoyable so you can ride longer.

No Shop Tools Needed: Tool-free elastomer change and a single-bolt seat clamp design for easy seatpost adjustments.

Works with Many Different Bike Types: This seatpost can be used on road bikes, gravel bikes, e-bikes (electric), commuter bikes, and adventure bikes for maximum comfort and performance.

Wide Range of Rider Weight: Weight limit of riders up to 150kg/330lbs.

Patented Parallel-Linkage Technology: Parallel Linkage technology stays in the direct path of the natural travel of the rear wheel. As a bump lifts the back of a bicycle, the rear wheel pushes up and forward into the rider.
