Tendon Joint Raceboard UF Essentials U-Pin Unifiber UF060011006

Tendon Joint Raceboard UF Essentials U-Pin Unifiber UF060011006

Description:

The Tendon Joint Raceboard UF Essentials U-Pin is a low-profile, high-performance tendon joint engineered for raceboard rigs. It provides a direct, secure connection between rig and board to help riders "close the gap" and maintain efficient power transfer at high speeds. Construction combines a high-quality TPU tendon and a single-piece stainless-steel U‑pin with two large-diameter custom bolts for easy tendon replacement without bolt overturning. An ergonomically shaped high-grade nylon pad locks the joint to the carriage while allowing smooth fore-aft travel in the mast track. A Spectra safety rope links top and bottom components and offers up to 650 kg break load for added security. Despite its robust materials, the design is lightweight—approximately 50 g lighter than many competing joints—improving responsiveness and reducing swing weight. Compatible with Unifiber Proteus V1/V2 and Starboard Phantom 2021 and newer models, it’s built for durability and race-day reliability.
