Value and Quality
Precision fit, effortless control.
Thirty‑stage precision damping is fully adjustable, letting you effortlessly switch between comfort and firmness. An external nitrogen reservoir delivers greater travel and faster heat dissipation, ensuring confident performance even in the most demanding conditions.
Engineering excellence, robust and reliable.
The needle rod features a hard chrome plating, while the barrel is made of high‑strength forged aluminum. Paired with a forged steel base and surface treatment, it stands up to grit and corrosion.
Extreme testing, lasting like new.
With 6 million fatigue‑life cycles, a 2.2‑inch single‑tube body, and a large 50 mm piston, it effectively suppresses thermal fade. A proprietary sealing design eliminates the risk of oil leakage, ensuring consistent performance over time.
A choice of value, embarking on long journeys with composure.
The PD+ model strikes the perfect balance between performance and practicality, featuring a backpack‑style nitrogen cylinder and 30 adjustable damping settings. With outstanding value and effortless installation, it ensures every journey is both reassuring and composed.
