The thrill of speed unites road cyclists. Whether professional or amateur, the fundamental goal is to push harder, chase speed and break free. Nothing embodies this better than the Reacto. The latest generation delivers fundamental changes that further improve its aerodynamics, reduce its weight and offer tyre clearance up to 32 mm, all while maintaining the comfort and control the Reacto is known for.
The ultimate all-rounder in Merida's Reacto range, the 10K offers the most balanced package in terms of overall aerodynamic performance and weight, tipping the scales at just 7.2 kg. With a wind tunnel reading of just 202 watts to maintain 45Km/h the 10K was optimised for head and cross wind aerodynamic performance making it perfectly suited for whatever a modern aero bike has to deal with on the open road.
