Extra Volume / EV Series
Suitable for general road riders, featuring adjustable spring preload + air preload auxiliary system and adjustable rebound damping.
The EV system, which increases gas volume in a limited space, effectively reduces heat generation during shock absorber operation, stabilizes oil temperature and damping force, and keeps performance in an optimal state.
The EV shock absorber is an entry-level choice for general road riders looking to initially improve vehicle stability.

.Monotube oil-gas separation
The damper adopts a monotube oil-gas separation design. The excellent heat dissipation performance of the monotube effectively reduces the operating temperature of the damping oil. The large-sized piston serves as the foundation for wide-range damping settings.
Oil-gas separation protects the damping oil from foaming, which would otherwise affect the stability of the damping force.
.High-sensitivity wide-range piston
The high-sensitivity wide-range piston, combined with a smooth oil passage design and diverse torque variations from the large piston, provides the necessary damping to appropriately reduce simple harmonic motion during low, medium, and high-speed (wide-range) operation.
.Adjustable spring preload + built-in air preload
Spring preload can be fine-tuned according to the rider's needs. Combined with built-in precision-calculated high-pressure inert gas to assist spring preload, it provides wide-range and simplified setup, saving time.
.Adjustable rebound damping
Effective 15-click rebound adjustment, allowing riders to adjust and set 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 the limited space, preventing the compressed gas chamber from becoming too small and generating high temperatures.
.Adjustable length
For some models, the maximum length is adjustable by 5mm, providing riders with the ability to adjust vehicle height, rake angle, and center of gravity transfer settings.
.12-month warranty
Quality service guarantee, providing a 12-month warranty on the damping damper (limited to Taiwan main island).
