The Secus upgrade delivers the first and only air spring system to really come indistinguishably close to the linear spring rate of a coil fork for the entire first 2\/3rds of its travel, with the advantage of a gentle end stroke progression to prevent bottoming without the “wall of force” harshness that excessively progressive springs create.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSecus Advantages:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAn enlarged negative air spring chamber delivers a soft, supple initial stroke for ultimate small bump compliance (yes, even compared to the Luftkappe)\u003c\/li\u003e\n\u003cli\u003eProprietary Midstroke Support Valve improves predictability and support beyond the sag point\u003c\/li\u003e\n\u003cli\u003eReduced lower leg pneumatic ramp means better scalability of the air spring, particularly for light riders who previously struggled to use full travel\u003c\/li\u003e\n\u003cli\u003ePlush and predictable like a coil, bottomless like an air spring\u003c\/li\u003e\n\u003cli\u003eAllows full use of travel in both directions - fully extends to top out without any quibbles (including on Debonair B1 air springs) and fully compresses without excessive ramp\u003c\/li\u003e\n\u003cli\u003eAllows more lower leg bath oil to be used for superior lubrication\u003c\/li\u003e\n\u003cli\u003eConsiderably lighter than coil conversions - adds approximately 130g\u003c\/li\u003e\n\u003cli\u003eSimple setup - inflate fork, bounce on it a few times, press MSV charge button, go ride\u003c\/li\u003e\n\u003cli\u003eCompatible with OEM volume spacers for end-stroke progression adjustment\u003c\/li\u003e\n\u003cli\u003eCompatible with other aftermarket top-cap systems such as DSD Runt and MRP Ramp Control\u003c\/li\u003e\n\u003cli\u003eLower compression ratios mean a more consistent spring rate\u003c\/li\u003e\n\u003cli\u003eTransferrable between any Secus-compatible forks with only a foot stud to change at most\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cb\u003eThree Stages of Control\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eBy independently optimising the beginning, middle and end portions of the stroke, the Secus gives you the linear-to-progressive spring rate that coil springs and traditional air springs alike wish they had.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eInitial stroke\u003c\/b\u003e - enlarged negative air spring chamber delivers a soft, supple initial stroke for ultimate small bump compliance\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMidstroke\u003c\/b\u003e - where traditional air spring rates drop off in the midstroke, our proprietary Midstroke Support Valve technology boosts the midstroke spring rate to maintain linearity, for support, predictability, ride height and compliance\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eEnd stroke\u003c\/b\u003e - enlarged lower leg volume reduces overall progression even at higher pressures and allows for a wider range of end-stroke ramp options to be utilised with standard fork volume spacers.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cb\u003e12 Month Crash Replacement Guarantee\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eVorsprung will replace any parts of your Secus damaged in the event of a crash or other accident for the first 12 months of ownership.
