Extra Volume / EV Series. Suitable for general road riders. Features adjustable spring preload + air preload assist system and adjustable rebound damping. The EV system increases gas volume within a limited space, effectively reducing heat generation during suspension operation, stabilizing damping oil temperature, and maintaining optimal performance. The EV shock is an entry-level choice for general road riders looking to improve vehicle stability. ．Monotube oil-gas separation: The shock absorber uses a monotube oil-gas separation design. The excellent heat dissipation of the monotube effectively lowers the operating temperature of the damping oil. The large-diameter piston serves as a foundation for wide-range damping force settings, while oil-gas separation prevents oil foaming, ensuring damping stability. ．High-sensitivity wide-range piston: Features a smooth oil passage design and diverse torque variations from the large piston, providing appropriate damping force to reduce simple harmonic motion during low, medium, and high-speed (wide-range) operation. ．Adjustable spring preload + built-in air preload: Allows fine-tuning of spring preload based on rider needs, supplemented by built-in high-pressure inert gas to assist spring preload, simplifying settings and saving time. ．Adjustable rebound damping: 15 effective clicks of rebound adjustment, allowing riders to customize their own handling style. ．Enlarged cylinder gas chamber: Based on Boyle's Law and the Ideal Gas Law, the internal gas chamber volume is increased within a limited space to prevent high temperatures caused by overly small compressed gas volumes. ．Adjustable length: Some models allow for up to 5mm of length adjustment, providing riders the ability to adjust vehicle ride height, rake, and center of gravity transfer. ．12-month warranty: Quality service guarantee, providing a 12-month warranty on the damping shock absorber (limited to Taiwan main island).
