Adding to an already legendary resume, EXT is proud to introduce the new Arma and Storia V4 Series. The V4 is specifically designed to raise the bar on what is possible in MTB damper performance technology. Don’t be fooled by the similar appearance to its V3 predecessor, for beneath the surface the V4 beautifully refines and improves what was already an industry game changer. Building off of their prestigious pedigree in motorsports racing, EXT has worked diligently to put out a damper that ensures its rightful place as innovative industry leaders in the highly competitive MTB marketplace.
The V4 not only retains and refines foundational aspects of the V3, such as its unique mid body damper characteristics, hydraulic bottom-out circuit and notable high speed control, while simultaneously addressing and integrating feedback from our riders. The V4 celebrates a position sensitive rebound hydraulic top out system, frequency dependent damping, an externally adjustable HBC and a steel DLC coated damper shaft. All of this and more coming in a stronger yet quieter package.
Features:
- 4 way adjustable (LSC-HSC-LSR-HBC)
- Unique patent pending PSR technology to avoid harsh top-out while improving bike platform stability
- New externally adjustable HBC Technology: no more bottom-out
- Allen key adjuster for both high and low compression valve
- LOK 2.0: optimized for every trail section
- High turbolent flow valves: no risk of cavitation
- Ø14 mm high strength chrome steel shaft with DLC ultra-low friction surface coating to increase durability
- Spring Thrust Bearings to improve straight alignment in case of spring side-load conditions
- Reservoir with large volume bladder design and very low reservoir pressure (55PSI) for maximum sensitivity
- New high viscosity index EV2S fluid developed throughout our off-road motorsport experience
- 30% lighter steel spring, designed from motorsport and tested to perform over 500,000 cycles
- Unique frequency dependent 1 way valve for best ride quality on rough terrain
- Wider and improved adjustment range with more defined sensitivity
- Weight: 397 gr. (210×55 mm. Standard mount – without spring)
