Merida Reacto 4000 Road Race Bike

The Merida Reacto 4000 delivers the thrill of speed at a price that’s hard to ignore, giving riders access to the latest Generation V aero frame technology without the premium price tag. Built around the lightweight CF3 carbon aero frame (approx. 1,185 g in size M), it shares the same aerodynamic shaping and stiffness values as Merida’s top-tier models, paired with the proven reliability of the Shimano 105 groupset and hydraulic disc brakes. With quality finishing kit and a fast-rolling wheelset, it’s the ideal entry point for aspiring racers and riders who want a seriously quick bike from day one.

Key Features

  • Lightweight CF3 carbon aero frame (approx. 1,185 g, size M)
  • Shimano 105 mechanical groupset with hydraulic disc brakes
  • Merida Expert CW handlebar and Expert SL stem
  • Merida Expert CW wheelset
  • Continental Grand Prix 28 mm tyres
  • Merida S-FLEX carbon aero seatpost
  • DISC COOLER braking heat-management technology
  • Tyre clearance up to 32 mm

Frame & Aerodynamics

The latest Reacto generation introduces refined tube shaping, reduced weight and deeper integration across the frame. The CF3 chassis mirrors the aerodynamic performance and stiffness of the flagship CF5, making only small weight concessions to deliver a more accessible package. With clearance for 32 mm tyres, the Reacto 4000 maintains the comfort and control the platform is known for, even on rougher roads or long race days.

Drivetrain & Performance

Shimano 105 offers smooth, reliable shifting and dependable braking performance in all conditions. It’s a groupset trusted by riders worldwide for its balance of durability, precision and value-ideal for those stepping into performance road cycling or preparing for their first races.

Wheels & Tyres

The Merida Expert CW wheelset provides a stable, aerodynamic platform for fast riding, while Continental Grand Prix 28 mm tyres deliver excellent grip, low rolling resistance and a comfortable ride feel. Together, they help the Reacto 4000 carry speed effortlessly across varied terrain.

Cockpit & Comfort

The Merida Expert CW handlebar and Expert SL stem create a clean, aerodynamic front end with reliable stiffness. Merida’s S-FLEX carbon aero seatpost adds compliance without sacrificing efficiency, while DISC COOLER technology improves braking heat dissipation on long descents or repeated hard efforts.

Who It’s For

The Reacto 4000 is perfect for riders who want a true aero race bike-the same frame shape as Merida’s pro-level models-paired with dependable components and upgrade potential. It’s ready to ride and race straight out of the box, and it’s a brilliant platform for riders progressing in the sport.
