Vorsprung Secus Fox A1 Fork Air Spring Upgrade Kit

Description Secus Advantages: An enlarged negative air spring chamber delivers a soft, supple initial stroke for ultimate small bump compliance (yes, even compared to the Luftkappe) Considerably lighter than coil conversions – adds approximately 130g Proprietary Midstroke Support Valve improves predictability and support beyond the sag point Simple setup – inflate fork, bounce on it a few times, press MSV charge button, go ride Reduced lower leg pneumatic ramp means better scalability of the air spring, particularly for light riders who previously struggled to use full travel Compatible with OEM volume spacers for end-stroke progression adjustment Plush and predictable like a coil, bottomless like an air spring Compatible with other aftermarket top-cap systems such as DSD Runt and MRP Ramp Control Allows full use of travel in both directions – fully extends to topout without any quibbles (including on Debonair B1 air springs) and fully compresses without excessive ramp Lower compression ratios mean a more consistent spring rate Allows more lower leg bath oil to be used for superior lubrication Transferrable between any Secus-compatible forks with only a footstud to change at most
