Cirrus Cycle, started in a little town in the Pacific Northwest. Here a passionate cyclist, frame builder, bike shop owner named Paul Barkley, began the journey that would see the idea of bike comfort forever changed. Cirrus Cycle's KINEKT Comfort in Motion; active suspension seatpost is a simple seatpost-based isolation system designed to provide you with the most comfortable and efficient riding experience. KINEKT marries comfort with performance by optimizing both!

KINEKT seatposts allow you to stay in the saddle over more terrain, maintaining a more consistent connection to your bike while isolating you from bumps and vibrations. Your body, bike, and surface create a linked system of moving parts. Excess movement throughout this system causes discomfort at delicate points of contact between rider and bike - you know what we're talking about!

Body Isolation effectively isolate your body from surface bumps and vibrations to improve comfort, control, and traction. You'll feel less fatigued from the decrease in bounce, which will allow you to have longer, more enjoyable rides. If you're not having more fun, something's wrong!
