Rinasclta Ultralight Carbon Road Disc Frameset | Only 850g Lightweight Carbon Disc Brake Frame with Free Headset

For riders who believe every gram matters, a lightweight road bike remains the ultimate choice for climbing, acceleration, and all-day efficiency. Unlike aerodynamic race bikes built for maximum speed on flat roads, a lightweight frameset focuses on responsive handling, rapid acceleration, and effortless climbing while offering the confidence and braking performance of modern disc brakes.

Drawing on over 10 years of carbon bicycle manufacturing experience, we proudly introduce our updated ultralight carbon road disc frameset. Constructed from premium Toray T800 and T1000 carbon fiber, the frame weighs just 780g (44cm) while maintaining excellent stiffness and durability. Combined with a tapered head tube, PF30 bottom bracket, and flat-mount disc brake design, it provides an outstanding platform for building your dream lightweight road bike.

1. Ultra-lightweight 780g carbon frame designed for climbing, fast acceleration, and efficient power transfer.

5. Premium Toray T800 + T1000 carbon fiber construction for the ideal balance of weight, stiffness, and strength.

The frameset includes a lightweight carbon fork, carbon seatpost, headset, and all essential hardware for assembly.
