Winspace M6 Ultegra Di2 — Build Your Dream Bike

Designed around modern aerodynamic principles, the M6 features a sculpted frame profile, optimized fork design, and fully integrated cable routing to minimize drag and maximize speed. The result is a bike that slices through the wind while maintaining exceptional control and stability at high speeds.

Advanced Carbon Construction

At the heart of the M6 is a precision-engineered carbon frame constructed from a blend of Toray T800, T700, M40 and ultra-high-modulus M60 fibers, strategically layered to balance stiffness, weight, and ride quality. This advanced carbon layup delivers excellent power transfer when sprinting or climbing, while maintaining compliance for long days in the saddle. 

With a frame weight of approximately 900g (size M) and a lightweight carbon fork, the M6 offers impressive efficiency without sacrificing durability or handling confidence. 

Built for Speed and Race Performance

Unlike many pure race bikes that prioritise stiffness alone, the M6 is designed to balance aerodynamics, comfort, and stability, allowing riders to maintain high speeds for longer. The refined geometry improves responsiveness and handling while ensuring confidence in fast corners, group rides, and long endurance efforts. 

The frame also supports tyres up to 32mm, providing additional comfort, grip, and versatility across varying road conditions.
