2027 Merida Reacto One
The most uncompromising and aerodynamically advanced REACTO ever. With a staggering 196 watts in Tour Magazine's wind tunnel test, the ONE sets a new internal benchmark for aero performance and is the fastest bike in the line-up. A unique 1x drivetrain with a Classified Powershift rear hub delivers a full 2x gear range, paired with super-slippery DT Swiss ARC wheels and a Continental Aero 111/Grand Prix 5000S TR tyre combo — all at just 7.4kg including the Rotor power meter.
