The Merida Reacto 9000 is built for riders who demand speed. Every detail has been refined to reduce drag, from the fully integrated cockpit to the hidden disc coolers behind the fork and rear triangle. Computational Fluid Dynamics (CFD) and wind tunnel testing helped shape the Reacto CF5, making it one of the most aerodynamically efficient road bikes ever tested by TOUR magazine.
Beyond aerodynamics, this bike prioritises rider comfort. Wider tyre clearance (up to 30c tyres) and a carbon aero seatpost help absorb road vibrations, keeping you fresh over long rides. Meanwhile, the Shimano Ultegra Di2 12-speed drivetrain ensures crisp, reliable shifting in all conditions.
Stopping power comes from Shimano Ultegra hydraulic disc brakes, which are mounted on aluminium Disc Cooler fins to reduce heat build-up by up to 35%, improving performance on long descents. The Reynolds BL60 carbon wheels provide the perfect balance of aerodynamics and handling, wrapped in Continental Grand Prix 5000S TR tyres for low rolling resistance and confidence-inspiring grip.
With its sleek aesthetics, top-tier performance, and cutting-edge aerodynamics, the Merida Reacto 9000 is a standout choice for riders looking to push their limits.
