The Merida Reacto Pro is built for riders who want a bike that combines aerodynamic efficiency with low weight and long-distance comfort. Whether you're racing, tackling demanding sportives or pushing the pace on fast club rides, it brings together premium components and an advanced carbon frame to help you ride efficiently over a wide range of terrain.
At the heart of the bike is Merida's latest Reacto CF5 carbon frame. Designed with aerodynamic tube profiles to reduce drag, it also sheds weight compared with previous generations while retaining the balanced handling the Reacto range is known for. Despite its aero focus, the frame offers clearance for tyres up to 32mm, giving you the option to increase comfort and grip on rougher road surfaces without compromising its fast character. Merida's Disc Cooler technology also helps dissipate heat from the brake calipers during long descents, supporting more consistent braking performance.
Comfort has been carefully considered alongside outright speed. The carbon S-FLEX seatpost is engineered to offer controlled vertical compliance, helping absorb road buzz and reduce rider fatigue on longer rides while maintaining pedalling efficiency. Combined with the increased tyre clearance, the result is a ride that remains composed over imperfect road surfaces without losing the responsive feel expected from a performance road bike.
Shifting comes from Shimano's flagship Dura-Ace Di2 2x12-speed groupset, delivering fast, accurate electronic gear changes with minimal effort. The wide gear range is suited to everything from steep climbs to fast-paced descents and sprint finishes. A factory-fitted 4iiii power meter integrated into the left crank arm provides accurate power data, making it easy to monitor training, pacing and performance.
DT Swiss ARC 1600 Spline carbon wheels complement the bike's aerodynamic design, helping maintain speed while remaining responsive when accelerating. They're paired with Continental Grand Prix TR 28mm tubeless-ready tyres, offering dependable grip, low rolling resistance and the option to run tubeless for improved puncture protection and comfort.
Finishing the bike is a fully integrated carbon cockpit that keeps cables hidden for a clean appearance while contributing to the bike's aerodynamic profile. A Prologo Scratch M5 saddle and an integrated Merida mini tool complete a specification that's ready for fast training rides, racing and long days in the saddle.
