LA PALMA, CALIF. - The new 444 Series shock from Progressive Suspension features what the company dubs its Frequency Sensing Technology (FST), a design that allows the shock to dynamically adjust damping while on the road.
FST is described by Progressive's engineering team as like having two sets of shocks on a bike. One set to comfortably and efficiently smooth away those nasty exposed aggregate road surfaces, weather cracks and expansion joints. The second set handles the big jobs like drainage dips, speed bumps, bottoming control and cornering stability.
This patent-pending technology features frequency sensitive damping circuits, an all-aluminum body, deflective disc valving and progressive spring rates. Like its predecessors, the 444 Series is preload adjustable by turning the top cap and can be easily set up for the rider's weight and riding style.
Available in black or chrome as well as standard and heavy duty spring rate and supported with a lifetime limited warranty.
