Product Description
The Merida Reacto 4000 combines both rider comfort and ultimate aerodynamics.
The Reacto incorporates wider tyres, a much neater cockpit cable integration and a series of incremental improvements to boost the performance and comfort of the frame.
Key Features:
- CF3 Fibre frameset with aerodynamic tube profiling
- Reacto CF3 full carbon forks for responsive handling
- Shimano 105 11 Speed groupset offers precise shifting
- Shimano 105 hydraulic disc brakes deliver powerful and faster-stopping speeds
- Continental Ultra Sport 3 Tyres ensure confident grip
- Colour: Red/Black
- Sizes: Small (52cm), Medium (54cm), Large (56cm), X Large (59cm)
Computational Fluid Dynamics (CFD) calculations were used to model performance in a virtual wind tunnel, guiding the changes which offered the most aerodynamic benefit.
The Reacto CF5 needs just 209 watts effort for 45 km/h speed, 1 watt faster than its predecessor so it’s in the leading group of aero road bikes ever tested by TOUR magazine.
Small details such as integrating the front disc cooler behind the fork and the rear disc caliper in the rear triangle and creating new bolt through axles with the thread integrated into the fork dropout minimise drag and improve aerodynamic performance. A myriad of small improvements over-compensate for the aerodynamic compromises made to give the Reacto bigger tyres, resulting in the perfect package of comfort, aerodynamic, lightweight and style.
