Merida Reacto 4000 Carbon Aero Road Bike | Uncompromising Speed & Performance
The thrill of speed unites road cyclists, and nothing embodies that pursuit better than the Merida Reacto. As the perfect entry point to Merida's high-performance aero range, the Reacto 4000 delivers professional-level aerodynamics at a price point that is hard to ignore. Built using the exact same super-aero frame profiles as top-tier flagship models, this machine is engineered to slice through the wind, reduce drag, and save you valuable watts on every ride.
At its core is a cutting-edge, lightweight CF3 carbon aero frame weighing in at approximately 1,185g (size M). Merida has completely optimized this latest generation to slash weight, maximize aerodynamic efficiency, and boost versatility with modern tire clearance for up to 32mm tires. Paired with a sleek Merida Expert CW handlebar and stem configuration, all cables are cleanly integrated to keep your cockpit incredibly neat and wind-resistant.
Powering your sprints and climbs is the utterly reliable Shimano 105 groupset, offering crisp, no-nonsense mechanical shifting. When it comes to slowing down, the matching Shimano 105 hydraulic disc brakes provide powerful, confident modulation in all weather conditions. To prevent brake fade on long, fast descents, the calipers feature integrated Disc Cooler technology to dissipate heat rapidly. Complete with an aerodynamic Merida S-Flex carbon seatpost to absorb road vibration and fast-rolling Continental Grand Prix 28mm tires, the Reacto 4000 is ready to race straight out of the box and serves as the ultimate platform to upgrade as your cycling progresses.
