Summary
The Merida Reacto is a highly regarded aero road bike that combines improved aerodynamics with comfort and versatility, making it suitable for race day and beyond. It features a clean, integrated cockpit, revised fork profiling, and a more comfortable ride thanks to updated carbon layup and an S-Flex seatpost. Reviews highlight its speed, efficient handling, and the ability to fit wider tires for added comfort.
Improved aerodynamics
More comfortable with revised carbon layup and S-Flex seatpost
Bigger tire clearance for added comfort and control
Clean, integrated cockpit solution
Wind tunnel-proven drag reduction
CF5 frames only include internal routing for electronic shifting

Not the most light-footed on very steep climbs
Merida’s Reacto aero road bike enters its fourth generation with an all-new carbon frame that through subtle updates is more versatile than ever while still improving on aerodynamics.
The Reacto 4000 offers a superbike-adjacent experience on a rather more real-world budget.
An aerodynamic jack of all trades!
