Xintai GP Edition <br/> Backpack-style mini twin-needle bar
● Back-mounted compact design: A compact nitrogen cylinder is mounted on the body, resulting in a small footprint and improved installation compatibility.
● Up-and-down needle design: Both the upper and lower ends feature precision, slender needle rods, resulting in extremely low moment of inertia and rapid response.
● Larger size: A larger barrel and piston than the PD version, offering a wider damping range and enhanced durability.
● 9+9‑stage manual adjustment: 9 compression stages (with simultaneous high‑ and low‑speed control) + 9 rebound stages, for precise tuning.
● All‑terrain compatibility: stable and reliable from paved roads to demanding off‑road conditions.

Product Description
GP Edition Backpack-Style Mini Double-Needle Stitching Machine ▪ Core Technology
Stability ![]() ![]() ![]() ![]() ![]() | Compact back-mounted gas cylinder The compact gas cylinder is integrated with the body, saving space while providing ample nitrogen capacity, and offers superior heat dissipation compared to a separate hose. |
Flexibility ![]() ![]() ![]() ![]() ![]() | Dual-round-head adaptive structure The upper and lower circular joints can automatically accommodate slight angular misalignments, preventing interference and extending the service life of the connector. |
Trip length ![]() ![]() ![]() ![]() | 9-stage compression and rebound are adjustable. High- and low-speed compression are synchronized and adjustable, with independent rebound damping—each offering nine distinct settings—to precisely accommodate road impacts and wheel retraction. |
Adjustment Options ![]() ![]() ![]() ![]() | Extra-large cylinder body and spring assembly The cylinder and piston have been enlarged, delivering superior resistance to thermal fade; the spring preload is adjustable, providing ample support and making it well-suited for heavy loads and challenging terrain. |
