Description

Winspace M6 Dura-Ace 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. 

Custom Build Options

  • Shimano Dura-Ace Di2 groupset, with lightning-fast, electronic shifting and world-class braking precision.   
  • The Carbon Project carbon  saddle weighing only 200g.
  • Choose your bar and stem size.  The Hyper Handlebar can be customised to your size preferences for width (380mm, 400mm, 420mm) and length (85mm-125mm).
  • Choose your cassette and crank length to customise the bike to your size preferences (162.5 - 175mm)
  • Choose your preferred wheel, rim depth and tire (28mm or 30mm, black/tan wall).  Choose between the UNAAS HARD2 (rim depth 50/45mm wavy) or another wheel set in the Winspace range (contact us to confirm pricing).

Aerodynamic Performance

Every tube shape on the M6 was developed using CFD aerodynamic analysis, allowing engineers to refine airflow around the frame and minimise drag across a wide range of riding speeds. 

Key aerodynamic improvements include:

  • Sharpened head tube profile to reduce frontal area
  • Ultra-wide aerodynamic fork architecture for improved airflow and stiffness
  • Patented dovetail rear wing fork design to smooth airflow across the frame 

These aerodynamic refinements allow the M6 to save up to 8.9 watts compared to the previous C5 Aero platform, helping riders maintain higher speeds with less effort. 

Race-Level Stiffness and Strength

The M6 was engineered to deliver exceptional structural performance under the intense forces generated during racing.

Testing and design targets include:

  • High bottom bracket stiffness for explosive power transfer
  • Reinforced head tube structure for precise steering control
  • Optimised fork stiffness for high-speed stability 

The frame structure is designed to withstand load forces equivalent to two tonnes, highlighting the durability built into the M6 platform. 

When riders accelerate, sprint, or attack climbs, the frame responds instantly — converting every watt directly into forward speed.

Modern Race Geometry

The M6 is designed with race-focused geometry to balance aggressive performance with stability.

Key geometry highlights include:

  • 410mm chainstay length for efficient power transfer and responsiveness
  • Optimised stiffness-to-weight ratio for improved acceleration and climbing efficiency
  • Integrated cockpit compatibility with Winspace Hyperbar system for aerodynamic control and clean cable routing 

This geometry delivers a confident ride feel whether sprinting out of corners, descending at speed, or driving the pace in fast group rides.
