The Merida Reacto is an entry-level carbon aero bike with race-proven ProTour geometry. It features the CF3 carbon frame and a Shimano 105 2x12-speed groupset paired with hydraulic disc brakes. Known for its class-leading aerodynamics and rider comfort, the 4th generation Reacto is more streamlined and efficient than ever. Wider tyres, refined cockpit cable integration, and numerous small performance enhancements make this bike a top contender in the aero category.
Aerodynamic performance was fine-tuned using Computational Fluid Dynamics (CFD) and wind tunnel testing, including the German TOUR magazine’s rigorous ‘moving leg dummy’ test. The result? The Reacto CF5 needs just 209 watts of effort to maintain a speed of 45 km/h—1 watt less than its predecessor, placing it among the best aero road bikes ever tested by TOUR magazine.
The Reacto’s innovative features, such as integrating the front disc cooler behind the fork, positioning the rear disc calliper within the rear triangle, and creating bolt-through axles with integrated threads in the fork dropout, all contribute to reduced drag and improved performance. The wider tyres add comfort without compromising aerodynamics, resulting in a bike that combines speed, comfort, and style.
Praised by leading cycling publications, Cycling Weekly called it "one of the most complete bikes available," Cyclingnews described it as "an utterly brilliant and faultless machine," and Cycling Plus was "hugely impressed." The Reacto’s hydraulic disc brakes are mounted on the chainstay for optimal braking force dissipation, enhanced by CNC aluminium Disc Cooler fins that reduce temperatures by up to 35%. This ensures consistent performance in all conditions, making the Merida Reacto a top choice for those seeking a high-performance aero road bike.
