Merida Reacto 4000 2026

Carbon Aero Road Bike

The Merida Reacto 4000 2026 is an entry-level carbon aero bike that brings ProTour race geometry to a wider audience, offering professional-level performance at an accessible price point. Built around the advanced CF3 IV carbon frame – sharing the same aerodynamic profile and geometry as the flagship CF5 IV – it blends state-of-the-art aerodynamics, rider comfort, and outstanding value. Equipped with the latest Shimano 105 2×12-speed mechanical groupset and powerful hydraulic disc brakes, this bike delivers exceptional speed, precision, and control on every ride.

Engineered through Computational Fluid Dynamics (CFD) and wind tunnel testing, the Reacto’s design leaves no detail to chance. From the integrated front Disc Cooler hidden behind the fork to the rear caliper neatly housed in the rear triangle, every feature is optimised to minimise drag. Even the bolt-through axles have been redesigned with threads integrated into the fork dropout for maximum aerodynamic efficiency. Wider tyre clearance up to 700x30c improves ride comfort without sacrificing speed, thanks to countless small refinements that more than offset aerodynamic trade-offs.

The Merida Reacto 4000 2026 also features heat-dissipating CNC-machined aluminium Disc Cooler fins that can reduce operating temperatures by up to 35%, ensuring consistent braking performance even on long descents. The Continental Grand Prix 700x28C tyres deliver low rolling resistance with dependable grip, while the Merida Expert CW wheels offer a perfect balance of stiffness and aerodynamics.
