2027 Merida Reacto One – Passion Red / Slate Grey
If ultimate speed is your goal, the 2027 Merida Reacto One is the most advanced road bike Merida has ever produced.
Designed with one purpose in mind – to go faster than anything before it – the Reacto One combines Merida's flagship CF5 carbon aero frame, a revolutionary Classified Powershift drivetrain, Shimano's legendary Dura-Ace Di2 electronic groupset, premium DT Swiss ARC 1100 wheels and a dual-sided power meter to create a superbike capable of competing with the very best machines in professional cycling.
In independent wind tunnel testing conducted by Tour Magazine, the Reacto One recorded an astonishing 196 watts, making it the fastest bike in the entire Reacto range and one of the most aerodynamically efficient road bikes available today.
Despite its aero credentials, the Reacto One weighs just 7.4kg, thanks to its ultra-light CF5 carbon frame, which tips the scales at approximately 950g (size Medium).
The result is a bike that climbs, descends and sprints with equal confidence while delivering race-winning aerodynamic performance.
Why Choose The Reacto One?
Merida's Fastest Aero Road Bike Ever
The latest generation Reacto represents a major step forward in aerodynamic efficiency. Every tube shape, surface and component has been refined to reduce drag while maintaining the comfort and handling that has made the Reacto a favourite among professional riders and amateur racers alike.
With tyre clearance increased to 32mm and significant weight savings throughout the frameset, the Reacto One is faster, lighter and more versatile than ever before.
Revolutionary Classified Powershift Technology
The Reacto One uses the innovative Classified Powershift rear hub, delivering the equivalent gear range of a traditional 2x drivetrain while retaining the aerodynamic and mechanical simplicity of a 1x setup.
Benefits include:
- Instant wireless shifting
- Reduced aerodynamic drag
- Lower weight
- Cleaner cockpit setup
