Name: Merida Reacto One 2027 - Road Bike
Brand: Merida

The most uncompromising and aerodynamically advanced Reacto ever. With a staggering 196 watts in the Tour Magazine's wind tunnel test, the Reacto One is the fastest bike in the line-up.

The latest generation delivers fundamental changes that further improve its aerodynamics, reduce its weight and offer tyre clearance up to 32 mm, all while maintaining the comfort and control the Reacto is known for. Aerodynamically optimised spec; a unique 1x drivetrain using the Classified Powershift Gear Hub to offer a full 2x gear range, combined with the super-slippery DT Swiss ARC wheels and Continental 111 tyre combo, allows the Reacto One to undercut the magic 200 watts mark by quite some margin. All this while coming in at only 7.4 kg. If you want to go fast, look no further.

Traditionally, there was a clear divide between aero and classic road bikes: the former focused on air-slicing capabilities, while the latter concentrated on weight and comfort. Fast forward to the REACTO V: not only have Merida been able to push it below the magical 200-watt barrier, but they have also reduced its weight further, making it possible to get the complete bike close to, if not below, the UCI weight limit of 6.8 kg. In terms of comfort, the REACTO's ability to accommodate up to 32 mm wide tyres, coupled with the lateral compliance properties of the S-Flex seat post, provides a ride quality comparable to that of a classic, thin-tubed road bike. In summary, the REACTO V, with its outstanding aerodynamics and ability to reach the UCI weight limit, delivers higher performance, greater speed and a more efficient ride than a classic road bike, which often focuses solely on weight.

While the new REACTO is another milestone in our technological and innovative history, setting new standards in terms of aerodynamics, as well as maintaining the perfect balance of air-slicing capability, comfort, and control, Merida's constant pursuit of marginal gains doesn’t end here. Through the lessons we learned and the processes they further refined while creating the new REACTO, are already able to explore additional ways to let key details trickle further down the REACTO range and find their way into their broader road and gravel offerings in the future. This drive is the foundation of REACTO's heritage and what it stands for.
