From Merida Reacto 9000 (2027) in the version Carbon UD (Silver) is the pinnacle of aerodynamic efficiency and lightweight technology. While other aero bikes often compromise on weight or comfort, the Reacto 9000 proves that a true speed specialist can also be an excellent climber and a comfortable partner for long rides.

The Absolute Topframe: CF5 Carbon

The heart of this machine is the CF5 carbon aero frame. This is the lightest and most advanced frame Merida produces, weighing only about 950 grams (size M). By using high-quality fibers and a complex lay-up, this frame offers unprecedented stiffness for direct power transfer, while the profile is optimized to cut through the wind with minimal resistance.

High-Quality Components with Powermeter

The Reacto 9000 is equipped with the electronic Shimano Ultegra Di2 12-speed groupset. This set delivers professional-level shifting performance: fast, reliable, and fully customizable via the app. A crucial detail for the ambitious cyclist is the standard included 4IIII powermeter, which allows you to monitor your power and progress with great accuracy.

Aerodynamics and Integration

Every part of this bike is chosen to minimize air resistance:

• Vision Metron 5D ACR EVO: This one-piece carbon cockpit is not only ergonomic and stiff but also provides fully internal cable routing. This results in an extremely clean look and significant watt savings.
• Reynolds BL 60 Expert DB: This 60 mm high carbon wheelset is designed to maintain maximum speed on flat terrain while ensuring stability in crosswinds.
• Continental Grand Prix 5000S TR: Fitted with 28 mm tires (tubeless ready), you benefit from the lowest rolling resistance and superior grip in corners.

Innovative Details and Comfort

Despite the focus on speed, comfort is not forgotten. The S-Flex seatpost with integrated rear light absorbs vibrations from the road surface, reducing fatigue during long rides. Additionally, the well-known Disc Cooler technology (cooling fins on the brake calipers) ensures that the hydraulic disc brakes stay cool and maintain their braking power even on long, Alpine-like descents.

Fast, agile, comfortable, and lightweight. The REACTO 9000 is the proven combination of the three pillars on which our REACTO concept is based: the perfect balance between aerodynamic efficiency, comfort, and control.

Top components combined with our latest Generation V REACTO frame create the perfect recipe for a top-level aero bike. With an abundance of aerodynamic efficiency, without compromising on weight, comfort, or the control REACTO is known for, the REACTO 9000 feels just as at home in races as during long club rides or fast, intense chain gang sessions.

The sensation of speed is what unites road cyclists. Whether you are a professional or an amateur, the fundamental goal remains the same: push harder, chase speed, and break away. Nothing embodies that better than the REACTO.

The latest generation REACTO builds on its predecessor, with fundamental changes that further improve aerodynamics, reduce weight, and allow for tires up to 32 mm, while maintaining the comfort and control REACTO is known for.

The REACTO ONE easily dips below the 200-watt threshold, measured according to Tour Magazine’s test standards, setting a new internal benchmark for aerodynamic performance. Other models within the range offer the perfect balance between aerodynamics, comfort, and control.

Whatever your focus — low drag, low weight, or all-round performance — in our latest lineup you’ll find the perfect REACTO.
