The 2025 Merida Reacto 8000 is a high-performance aero road bike that brings together cutting-edge technology, exceptional aerodynamics, and a rider-first approach to comfort and handling. Designed for serious racers and performance-driven enthusiasts alike, the Reacto 8000 is built around Shimano's latest Ultegra 12-speed Di2 groupset, paired with the impressive Reynolds AR60 DB carbon wheelset, making it a true contender for those who want to dominate both flat sections and steep climbs.
Key Features:
- CF3 carbon frame (1,150 g in size M): Built for speed, the lightweight CF3 frame enhances acceleration and power transfer, while providing excellent aerodynamics.
- Shimano Ultegra 12-speed Di2 groupset: This electronic shifting system ensures lightning-fast, precise gear changes, making it a reliable choice for competitive racing.
- Reynolds AR60 DB carbon wheelset: These high-performance wheels, fitted with Continental Grand Prix 5000S TR 28 mm tyres, deliver superior aerodynamics, reduced rolling resistance, and great control on varied road surfaces.
- Vision Metron 5D ACR EVO one-piece cockpit: Fully integrated for aerodynamic efficiency, this cockpit provides a sleek look while enhancing control.
- DISC COOLER technology: Built into the braking system to maintain optimal performance on long descents, this innovation helps reduce brake temperatures by up to 35%.
- MERIDA S-FLEX carbon aero seat post: Adds to the bike’s already impressive comfort, helping to smooth out road vibrations for a more comfortable ride on long, demanding rides.
Performance Focused:
The Reacto 8000 is designed for unadulterated speed, perfect for criterium racers, sprinters, and those who demand high levels of performance. The bike excels in delivering quick acceleration, sharp handling, and aerodynamic advantages, while maintaining a lightweight frame that doesn't compromise on comfort. The integration of wider tyres further enhances its ability to tackle rough roads and cobblestones, making it as versatile as it is fast.
This latest version of the Reacto builds on the proven success of previous models, incorporating the latest trends in aerodynamics and rider-focused improvements. These include wire port cable integration for a cleaner look and reduced drag, and a refined braking system that includes flat-mount calipers positioned on the chainstay for better force dissipation.
Real-World Proven:
The Reacto has always been at the cutting edge of aero bike design, but this fourth-generation model takes things further. Computational Fluid Dynamics (CFD) analysis and wind tunnel testing have helped fine-tune the frame’s aerodynamic profile. For instance, the bike requires just 209 watts of effort to maintain a speed of 45 km/h, making it one of the most aerodynamically efficient bikes ever tested by Tour Magazine.
Small but impactful details, such as integrating the front disc cooler behind the fork and embedding the thread into the fork dropout, further minimize drag while ensuring precise braking control. These details make the bike race-ready, whether for high-speed sprints or challenging hill climbs.
