Description

The Merida Reacto 5000 (2026) in glossy black is a class-leading aero road bike that combines state-of-the-art aerodynamics with real rider comfort, built for serious racers, ambitious road cyclists and enthusiasts alike.

At its heart is a lightweight CF3 carbon aero frame with race-proven ProTour geometry, sharing the same aerodynamic profiling as the flagship CF5 with a more accessible carbon layup. Refined through Computational Fluid Dynamics and wind-tunnel testing, it integrates the front Disc Cooler behind the fork, tucks the rear caliper into the rear triangle and uses full Wire Port cable integration — details that minimise drag and manage brake heat. A Merida S-Flex seatpost and up to 30c tyre clearance add impressive comfort on long rides and rougher roads.

The complete Shimano 105 Di2 electronic 2x12 groupset delivers fast, precise and reliable shifting at the press of a finger, while the Vision Team 35 wheelset and tubeless-ready Continental Grand Prix TR 28c tyres balance speed, grip and control. Shimano 105 hydraulic disc brakes provide confident stopping in all conditions.

Ideal for criterium racers and ambitious road riders who want a fast, aerodynamic and genuinely comfortable carbon bike with electronic shifting.

Shimano 105 Di2

The Shimano 105 Di2 marks the arrival of electronic transmission in the 105 range, renowned for its excellent performance/price ratio. Designed for demanding cyclists, it offers fast, precise and reliable gear changes, with the ease of use typical of Shimano electronic groupsets. Thanks to Di2 (Digital Integrated Intelligence) technology, the derailleurs are electronically actuated, guaranteeing smooth and consistent gear changes, even under heavy load. This precision improves driving comfort and allows you to stay focused on the road.
