Summary
The Merida Reacto is a highly regarded aero road bike that combines improved aerodynamics with increased comfort and versatility. It features a fully integrated cockpit, revised fork profiling, and an S-Flex seatpost for enhanced ride quality. While it excels in speed and handling, some reviews note its stiffness and the need for wheel upgrades to fully realize its potential.
Improved aerodynamics
Increased tyre clearance
More compliance
Fully integrated cabling
S-Flex seatpost for comfort
Can feel excessively rigid
Wheelset is a weak point
Front end susceptible to crosswinds
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 new Reacto makes the race choice easier, there’s no longer a need to pick comfort over aero performance on race day.
The Reacto is a genuinely excellent bike.

One month into our longterm test and the Merida Reacto LTD road bike is already impressing us
Effortless straight-line speed
Scything high-speed cornering capabilities
Dampening when dealing with large impacts
Doesn't come with tubeless tyres as standard
The rear light is far from reliable

A fast machine with sorted geometry, but its firm ride won't appeal to all
