Description
Aero Speed Meets Everyday Versatility
The Merida Reacto 4000 2025 is built for riders who want aerodynamic speed, racing efficiency, and all-day comfort in one package. At its heart lies the CF3 carbon frame, weighing just 1,150 g (size M) and shaped for maximum aerodynamic efficiency without compromising ride quality. Its race-proven geometry ensures sharp handling and fast acceleration, making it the perfect partner for crits, sprints, or long club rides.
Comfort Meets Control
Despite its aggressive aero design, the Reacto 4000 doesn’t sacrifice comfort. With clearance for up to 30 mm tyres and a MERIDA S-FLEX carbon aero seat post, it smooths out rough tarmac and potholes, helping riders stay fresher for longer. The DISC COOLER brake technology enhances heat management on long descents, ensuring consistent performance and safety.
Premium Performance at Great Value
Equipped with the latest Shimano 105 12-speed mechanical groupset, the Reacto 4000 delivers crisp, reliable shifting and powerful braking at an outstanding value point. Integrated WIRE PORT cable routing keeps the cockpit sleek and aerodynamic, while the included seatpost-integrated rear light enhances visibility on the road.
