Just in: Merida Reacto 5000

A carbon-fibre aero road bike with Shimano Ultegra components for £2,000 The Merida Reacto 5000 aero road bike has just arrived for testing here at road.cc. Boasting a carbon-fibre frame, a mainly Shimano Ultegra groupset and Fulcrum Racing Quattro wheels, it costs £2,000.

We’re all familiar with aero road bikes these days, right? The reasoning goes that saving weight on a frameset is an overrated factor that’s only really significant when you’re accelerating or climbing a very steep hill. At other times, aerodynamic efficiency is much more important.

With that in mind, the Reacto 5000 is built using Merida’s Fastback tube profiles which are based on the NACA (National Advisory Committee for Aeronautics) 0028 airfoil. The tail of the profile is cut away in such a way as to keep the airflow stable without causing turbulence. This lowers the weight and allows Merida to stay within the UCI’s rules on tube dimensions. Other brands do similar things with their aerodynamic shaping.

The seatstays meet the seat tube much lower than the top tube junction, reducing the frontal area, and they’re positioned well out from the rear wheel to manage airflow back there. The legs of Merida’s full-carbon Pro-Direct fork are widely […]
