About the Merida Reacto 4000
Merida's Reacto platform represents years of aerodynamic development, with every tube shape optimised for minimal drag. The CF2 carbon frame delivers impressive stiffness for explosive acceleration while the NACA-inspired profiles slice through the air. The integrated cockpit and hidden cable routing further reduce wind resistance.
The Reacto 4000 sits at the sweet spot of Merida's aero range, offering race-ready performance with a Shimano 105 groupset and deep-section wheels. Disc brakes provide confidence-inspiring stopping power regardless of conditions, while the S-Flex seatpost insert adds comfort compliance for long days in the saddle. It's a bike that rewards riders who love to go fast.
