Merida Reacto 4000 Carbon Road Bike 2023

Description

Entry level carbon aero bike with race proven ProTour geometry equipped with Shimano 105 drivetrain and hydraulic disc brakes.
The Merida Reacto has always been a class leading aero bike combining state of the art aerodynamics with rider comfort. The 4th generation model is more slippery and beautiful than ever incorporating wider tyres much neater cockpit cable integration and a series of incremental improvements to boost performance.
In the world of Pro-Tour racing no area can be ignored. Computational Fluid Dynamics (CFD) calculations were used to model performance in a virtual wind tunnel guiding the changes which offered the most aerodynamic benefit: Prototypes were wind tunnel tested following the German TOUR magazine standard including the ‘moving leg dummy’ test.
The Reacto CF5 needs just 209 watts effort for 45 km/h speed 1 watt faster than its predecessor so it's in the leading group of aero road bikes ever tested by TOUR magazine. Small details such as integrating the front disc cooler behind the fork and the rear disc caliper in the rear triangle and creating new bolt through axles with the thread integrated into the fork dropout minimise drag and improve aerodynamic performance.
A myriad of small improvements over-compensate for the aerodynamic compromises made to give the Reacto bigger tyres resulting in the perfect package of comfort aerodynamic lightweight and style. A long string of test wins perfect scores and awards confirm the successful evolution of the race-proven DNA of the previous model with the latest trends and technologies.
Cycling Weekly described it as 'without doubt one of the most complete bikes available on the market' Cyclingnews 'an utterly brilliant and faultless machine' and Cycling Plus were 'hugely impressed'.
All Reacto come with powerful hydraulic disc brakes. Calipers are mounted on the chainstay for better dissipation of braking forces using the flat mount standard for a neat flush fit. Calipers sit on top of CNC'd aluminium Disc Cooler fins which reduce operating temperatures by up to 35%.
