The thrill of speed unites road cyclists. Whether professional or amateur, the goal is to push harder, chase speed and break free. Nothing embodies this better than the Merida Reacto.
The Merida Reacto 5000 road bike is built around Merida's latest CF3 carbon fibre aero frame, which is lighter, more aerodynamic and more comfortable than previous generations.
With tyre clearance up to 32mm, it handles rough UK roads better than older aero frames while giving nothing away in terms of speed. In the Merida Reacto 5000 Green (Halo Green Grey), it looks every bit as sharp as it rides.
Speed at a sensible price
The Reacto One platform substantially undercuts the 200-watt barrier as measured by Tour Magazine's test standards, setting a new internal benchmark for aerodynamic performance. The Reacto 5000 shares that same frame platform, meaning you get Merida's most aerodynamic road frame ever at an accessible price point.
Any informed review of the aero road bike market in the UK right now would struggle to find a better-specced Merida carbon aero bike at this level. For riders asking what the best aero road bike under £3,500 might be, this one belongs on the shortlist.
Shimano 105 Di2 electronic groupset
Pairing the CF3 frame with Shimano's 105 Di2 electronic groupset is a smart move at this price. As a carbon road bike with 105 Di2, the Reacto 5000 gives you precise, wireless shifting and hydraulic disc brakes without the cost of Ultegra. The shifts are crisp, consistent, and completely reliable in all conditions, wet winter commutes included.
Wheels and tyres that perform
The Vision 35 tubeless-ready wheelset paired with Continental Grand Prix TR 28mm tyres gives you a ride that's fast, grippy, and forgiving on anything other than perfect tarmac. Running tubeless drops rolling resistance and improves puncture protection, a genuine advantage on British roads.
Comfort built into an aero frame
The MERIDA S-FLEX carbon aero seatpost adds a degree of vertical compliance that takes the edge off rough surfaces on longer rides. The frame weight comes in at approximately 1,185g in size M, which keeps the overall bike weight low enough that climbing and acceleration feel sharp and responsive.
