EXT Storia V4
Core Features 4 way adjustable (LSC-HSC-LSR-Lok 2.0 proprietary system) Unique patent pending PSR hydraulic top out technology to avoid harsh top-out while improving bike platform stability and predictability Adjustable Hydraulic Bottom-out Circuit (HBC) Technology: our end stroke damping technology that has revolutionized the MTB damper market has been refined even further ensures predictable end-stroke characteristics to allow the user full utilization of travel of the bike while virtually eliminating harsh rebound effects. Introduction of more commonly found 5mm Allen wrench adjuster for high compression valve vs. the previous 12mm wrench adjuster LOK 2.0: optimized for pedaling but perfectly at home on every trail section due to an integrated threshold by-pass circuit. High turbulence flow valves provide a balanced and controlled damping profile while simultaneously minimizing risk of cavitation Ø14 mm chromoly shaft utilizing diamond like carbon (DLC) coating via physical vapor deposition (PVD) provides state of the art ultra-low friction properties and increased durability from impacts and wear Tapered Spring Thrust Bushings to improve straight alignment in case of spring side-load conditions Large volume reservoir using a bladder design and very low reservoir pressure (55PSI) ensures maximum sensitivity High viscosity index oil provides consistency through even the most tortuous of conditions 30% lighter steel spring, designed from motorsport and tested to perform over 500,000 cycles Designed for Enduro / Trail riding Price is for damper only. Springs are available on the product page and a 2nd spring can be purchased at a discounted rate. Note: AFMLOW RIDERS: Due to the tight frame clearance on Amflow frames, we are recommending a maximum rider weight of 230lbs. To ensure frame clearance, riders over a 170lb will most likely require and be shipped with a C55 spring-size. C55 spring rates max out at 650lbs rate, which calculates to a 230lb rider weight. If you are over the recommended maximum rider weight, your spring may touch your frame under full compression.
