The Reacto 9000 is built around Merida's top-level CF5 carbon frame, the same race-proven aero platform used at the highest level of road racing, combining state-of-the-art aerodynamics with rider comfort. The fourth-generation Reacto is slipperier and better looking than ever, with wider tyres, much neater cockpit cable integration and a series of incremental improvements that add up to more performance.

Merida used Computational Fluid Dynamics (CFD) to model performance in a virtual wind tunnel and guide the most beneficial changes, then tested prototypes to German TOUR magazine's standard, including its moving-leg dummy test. The Reacto CF5 needs just 209 watts to hold 45km/h, one watt faster than its predecessor and among the quickest aero road bikes TOUR has tested. Details like tucking the front Disc Cooler behind the fork, integrating the rear caliper into the rear triangle and designing thru-axles with the thread built into the fork dropout all reduce drag.

The 9000 is built with Shimano Ultegra Di2 2x12 shifting, Reynolds BL60 carbon wheels with Continental GP5000S TR 28mm tyres, and a fully integrated Vision Metron 5D carbon cockpit. Flat mount Ultegra hydraulic disc brakes sit on Disc Cooler fins that cut operating temperatures by up to 35%, and Cycling Weekly called the Reacto "without doubt one of the most complete bikes available on the market".
