Merida Reacto 5000 Carbon Di2 Aero Road Bike | Electronic Precision & Elite Speed
The thrill of speed unites road cyclists, and nothing embodies that pursuit better than the Merida Reacto. Benefit from our fastest ever road bike frame without blowing the budget.
The Reacto 5000 pairs Merida's benchmark lightweight CF3 carbon aero frame (~1,185g, size M) with the cutting-edge precision of electronic shifting to create a ride that is almost as fast as our top-tier pro-level bikes. It delivers a blend of speed, premium performance, and value that is hard to beat.
Engineered to slice through the wind, this latest-generation frame shape features optimized aerodynamics, integrated cable routing, and expanded tire clearance for up to 32mm tires. Up front, the sleek Merida Expert CW handlebar and Expert SL stem setup minimizes drag. To ensure long-distance comfort alongside pure speed, the aerodynamic Merida S-FLEX carbon seatpost features built-in compliance to actively dampen road vibrations.
The headline feature is the Shimano 105 Di2 electronic groupset, offering lightning-fast, ultra-precise electronic shifting at the press of a button with zero mechanical cable stretch over time. Matching Shimano 105 hydraulic disc brakes deliver confident, modulated stopping power in all weather conditions, while integrated Disc Cooler technology rapidly dissipates heat to prevent brake fade on fast descents. Rolling on a race-ready Vision 35 tubeless-ready wheelset paired with premium Continental Grand Prix TR 28mm tyres, the Reacto 5000 is an incredibly fast, modern package built to help you break free.
