LUNJE Factory OEM Service for Suspension Seatposts, ISO and SGS Certified Professional Bicycle Components

50mm Travel Suspension Spring with Adjustable Preload Screw, LUNJE P003 Coil Damping System

🌟 Why Choose XT-P003? (B2B Highlights)

CNC One-Piece Head: Unlike cheap stamped heads, LUNJE uses a CNC-milled head that is integrally formed with the clamp. This ensures the saddle stays rock-solid even on rough terrain.

50mm Smooth Travel: The internal coil spring effectively absorbs high-frequency vibrations from cobblestones, gravel, and trails, protecting the rider's spine and lower back.

Universal Compatibility: With sizes ranging from 27.2mm to 31.6mm, this is a "Must-Have" stock item for wholesalers serving the MTB, Trekking, and E-city bike markets.

Ready for E-Bike Conversion: Ideal for E-bike riders who travel longer distances and require higher comfort levels.
