Elite-level aero performance, without the WorldTour price tag. The Merida Reacto 8000 2027 delivers near top-tier speed using the advanced CF3 carbon aero frame, paired with Shimano Ultegra Di2 electronic shifting and Reynolds AR60 carbon wheels for maximum efficiency on the road.

Sharing the same wind-tunnel developed aerodynamics and frame stiffness figures as Merida’s flagship CF5 platform, the Reacto 8000 offers true race-bike performance with only minimal weight differences. The result is a fast, responsive, and incredibly efficient aero road bike built for serious riders.

The latest Reacto generation is lighter, faster, and more versatile than ever, now with tyre clearance up to 32mm, giving you the ability to run wider tyres for improved comfort, grip, and real-world speed.
