2027 MERIDA REACTO ONE FRAMESET
The Ultimate Aero Platform
When only the fastest will do.
The new 2027 Merida Reacto One Frameset represents the pinnacle of Merida's aero engineering. Developed using extensive CFD analysis, wind tunnel testing and real-world racing feedback, this is the same fifth-generation Reacto platform that has already become one of the most talked-about aero road bikes of the year.
The new CF5 V carbon frameset is lighter, more aerodynamic and more comfortable than the previous generation while retaining the incredible stiffness and handling that made the Reacto famous. Independent testing has shown the new Reacto to be among the fastest aero bikes currently available, yet it's still practical enough to run up to 32mm tyres for real-world speed and comfort.
Whether you're building the ultimate race bike, dream aero machine or time trial weapon for fast road riding, the Reacto One Frameset gives you complete freedom to choose every component exactly how you want it.

Wind Tunnel Proven Speed
The new Reacto isn't just another aero bike.
Merida worked extensively with Reynolds and aerodynamic specialists to redesign almost every area of the bike.
The result is:
- Reduced aerodynamic drag
- Lower overall weight
- Improved rider comfort
- Increased crosswind stability
- Faster integrated cockpit
- Improved airflow around wheels and frame
In independent testing, the flagship Reacto platform achieved one of the lowest aerodynamic drag figures ever recorded in TOUR Magazine's wind tunnel testing.

Why We Love It
There are lots of fast aero bikes available today, but very few combine outright speed, sensible pricing, superb handling and practical tyre clearance like the new Reacto.
The latest frame feels incredibly responsive under power while remaining remarkably comfortable over long distances. It inspires confidence on technical descents and remains stable in crosswinds, making it one of the easiest aero bikes to ride fast in real-world conditions.
