Merida Reacto 4000 Carbon Road Bike in Black/Gunal Grey

Season:2027

Brand:Merida

Code:P-S077

The latest generation of the Merida Reacto 4000 delivers fundamental changes that further improve its aerodynamics, reduce its weight and offer tyre clearance up to 32 mm.

The Reacto 4000 uses exactly the same super-aero frame shape as Merida's top level models. Using the utterly reliable Shimano 105 groupset with hydraulic disc brakes and some choice components, it is ready to ride and race from the box, as well as being a great platform to upgrade as you progress. Featuring Merida's lightweight CF3 carbon frame with race-proven geometry, the Reacto 4000 is far from an entry-level bike, but if you are starting out in road racing or want a fast and well-balanced aero road bike, then it is a perfect choice.

The Reacto 4000 offers impressive comfort due to the generous tyre clearance and the fitted S-FLEX carbon seat post. At the same time, the latest super smooth mechanical 12-speed Shimano 105 groupset keeps shifting and braking in perfect check. This is the ideal aero bike for your first steps into the racing world as well as challenging club rides. Its outstanding aerodynamic performance, reduced weight, sharp handling and super quick acceleration makes it the perfect bike for criterium racers and sprinters. At the same time, the class-leading comfort gives it the ability to play out its aerodynamic advantage also on the cobblestones or the idyllic but potholed littered lanes of your favourite training ride.
