Introducing the 2027 Merida Reacto (GEN 5) Range
We headed out to Benicàssim, Spain for the launch of the new Reacto. A highly anticipated bike for us here – we couldn’t wait to get out hands on the new product. As the previous generation Reacto was Merida’s most highly awarded bike, the stakes were high to see how they would change this incredible machine. We were not disappointed.
A complete guide to the brand new Gen 5 Reacto. The fastest, most advanced aero road bikes yet.
The 2027 Merida Reacto lineup marks the biggest leap forward in the bike’s history. Every model—from the entry‑level Reacto 4000 to the flagship Reacto Pro—shares the same design philosophy: maximum aerodynamic efficiency, reduced weight, improved comfort and class‑leading control. Whether you’re racing, chasing personal bests or simply addicted to the feeling of speed, the new Reacto range is built to help you ride faster, further and with more confidence than ever.
Ride Feel
The Reacto is insanely fast. Jose Hermida led out a 52km group ride and the pace was hot from the get-go. Luckily the Reacto rewards every watt you can put through the pedals. As we rode down the coast cycle path at warp speed, dodging pedestrians and rough patches of tarmac I instantly got to grips with the bikes handling, and confidence to push came quickly.
When it came to descending, I was happy to push and lean in. Manuel, our model for the day, was also really impressed with the Reacto’s ability to descend confidently at speed and made the same comment. It’s a bike you can ride flat out and feel like a hero!
What’s New for 2027
The latest generation Reacto introduces several major updates that run across the entire range:
- Refined aerodynamics — reshaped tube profiles and deeper integration reduce drag significantly.
- Lower weight — both CF5 and CF3 framesets shed grams without sacrificing stiffness.
- Tyre clearance up to 32 mm — more comfort, more grip, more versatility.
- Improved comfort — the S‑FLEX seatpost and frame shaping smooth out rougher roads.
- Better heat management — DISC COOLER technology keeps braking consistent on long descents.
- Shared DNA across the lineup — even the most affordable models use the same aero frame shape as the pro‑level bikes.
The result is a platform that feels faster everywhere: on climbs, in sprints, on rolling terrain and in the wind.

The Reacto has always been fast, but the 2027 range pushes the concept further:
- Every model feels like a race bike, even the entry‑level 4000.
- Comfort is dramatically improved, making long rides and rough roads easier.
- The aerodynamic gains are real, especially at higher speeds.
- The lineup is more accessible, with electronic shifting and carbon wheels appearing at lower price points than ever.
It’s a range built for riders who want to go fast—whether that’s in a race, on a club ride or simply chasing the thrill of speed on their own.
