Suitable for electric dirt bicycles, downhill bicycles, for example：rawrr/e-ride pro SS/ninebot/surron/talaria sting/czem/ewatt/vtb/ventus/bse Stable Performance: The external nitrogen canister resolves issues of cavitation and performance degradation found in traditional shock absorbers. Responsive: Adjustable rebound speed allows adaptation to various terrains and riding styles. Durable and Efficient: Superior heat dissipation makes it ideal for prolonged high-intensity use. Providing Support and Absorbing Impact: The coil spring in the shock absorber compresses under force, converting external vibrations into stored elastic energy, which is released after the impact ends.Adjustable Preload: Users can adjust the preload to suit riders of different weights or various terrain conditions, altering the spring's initial support characteristics. Controlling Spring Compression and Rebound Speed: The hydraulic oil inside the shock absorber flows through damping valves or orifices, generating resistance (damping force) to regulate the spring’s motion and prevent excessive compression or rebound.Adjustable Compression Damping: The damping system controls the compression speed of the shock absorber during impacts, ensuring it quickly adapts to road shocks.Adjustable Rebound Damping: After an impact, the shock absorber slowly returns to its original length, controlled by the rebound damping system, preventing excessive bouncing on uneven terrain and improving ride stability. The external nitrogen canister is a critical upgrade for spring-damped shock absorbers, serving the following functions: During high-speed operation, the hydraulic oil inside the shock absorber may generate bubbles (cavitation) due to pressure changes, leading to unstable damping performance.The external nitrogen canister uses a diaphragm or floating piston to separate the nitrogen gas from the hydraulic oil, preventing bubble formation and ensuring consistent damping force. The nitrogen canister is filled with high-pressure nitrogen gas (typically 100-200 psi), which offers additional cushioning and support to the hydraulic system during compression.This design is especially effective in high-frequency vibrations or intense impacts, such as during off-road cycling. By increasing the total volume of hydraulic oil and exposed surface area, the external nitrogen canister improves heat dissipation, helping prevent performance degradation during prolonged rides. Spring Preload Adjustment Easily customize spring tension to match your weight, riding style, and terrain (e.g., downhill, trail, or urban riding) for optimal shock absorption and comfort. External Nitrogen Reservoir Heat Dissipation: The external reservoir reduces heat buildup during intense rides, ensuring consistent damping performance even on long descents or technical trails.Smooth Operation: Oil-air separated damping technology prevents foaming and maintains fluid stability, delivering a plush and responsive ride.Customizable Control: Adjustable preload and rebound settings allow you to fine-tune the shock to your weight, riding style, and terrain. Rebound Damping Adjustment Terrain Adaptability: Slow down rebound for technical trails to maintain traction, or speed it up for smooth roads to maximize efficiency.Personalized Ride: Adjust the rebound speed to match your riding style, whether you’re a downhill racer, trail enthusiast, or casual rider.Enhanced Stability: Prevent bouncing or “kickback” after impacts, ensuring a smooth and controlled ride. Compression Damping Adjustment Impact Absorption: Adjust compression resistance to absorb large hits (e.g., jumps) while maintaining sensitivity for small bumps.Ride Customization: Stiffen compression for high-speed stability on smooth trails, or soften it for plush control on rocky terrain.Progressive Response: Prevent bottoming out during heavy impacts, ensuring consistent performance under extreme loads.
