Progressive Dampening System
The Progressive Dampening System is a game-changer for riders seeking greater control in there suspension performance. Designed to replace the OEM spring perch (or seat), the PDS offers advanced bottoming resistance and a more progressive feel, ideal for those who need added support without sacrificing comfort.
What the PDS Delivers
The PDS is for riders who want to maximize their fork’s performance. By regulating fork oil through a series of strategically placed ports, this system delivers greater bottoming resistance and adjustability across a range of settings. Whether you prefer a softer suspension for comfort, or firmer settings for high-speed control, the PDS system can be tailored to your riding style. Key benefits include:
- Enhanced Bottoming Resistance: Perfect for riders running softer valving who want to avoid harsh bottom-outs, even on aggressive terrain.
- Progressive Mid-Stroke Control: The PDS provides added support and hold-up in the mid-stroke, giving you a stable and responsive front end.
- Advanced Hydraulic Support for Fast Riders: The PDS provides riders with the ability to achieve a firm, controlled feel that adapts to riding speed.
