Merida’s latest iteration of the Reacto series, the fifth generation unveiled in early 2026, marks a significant evolution in aerodynamic road bike design. This model not only refines the Reacto’s performance but also introduces innovative features that set it apart in the competitive aero bike market.
Aerodynamic Advancements
The Reacto V showcases a deeper head tube and a more sculpted fork design, aligning with the UCI’s updated 8:1 tube ratio regulations. These modifications enhance airflow, reducing drag and improving overall speed. The integration of the “Seagull Wing” cockpit, developed in collaboration with Vision, further contributes to a 5% aerodynamic gain over its predecessor. This cockpit design, initially deemed UCI-illegal due to its width, is now available for amateur riders seeking maximum aerodynamic advantage. (cyclingnews.com)
Structural Refinements
Merida has optimized the frame’s geometry to accommodate wider 32mm tires, offering improved comfort without compromising speed. The redesigned seat tube features a unique cutout between the bottom bracket and seat stay junction, reducing weight and enhancing aerodynamics by approximately one watt at 45 km/h. (cyclist.co.uk)
Weight Reduction and Stiffness
The Reacto V achieves a weight reduction of approximately 110 grams compared to its predecessor, bringing the frameset closer to the UCI’s 6.8 kg weight limit. This reduction is largely attributed to the new S-Flex seatpost and a minimalist seatpost clamp design. Additionally, the frame’s bottom bracket area has been reinforced to increase stiffness, enhancing power transfer and ride responsiveness. (cyclist.co.uk)

Performance and Handling
Initial test rides in Spain have highlighted the Reacto V’s exceptional handling and comfort. The bike offers a direct and aggressive acceleration, with a long and low riding position that enhances aerodynamics. The lightweight Vision wheels in the Team edition contribute to its climbing ability, ensuring that riders do not feel burdened by excess weight. The Reacto V’s design and performance make it a compelling choice for both competitive cyclists and enthusiasts seeking a high-performance aero bike. (cyclingweekly.com)
