CF5 V Aero Race Platform
The Reacto One uses Merida’s Reacto CF5 V carbon frame together with the dedicated CF5 V Disc fork. It’s a platform focused firmly on aerodynamic road performance, whether you’re racing or pushing the pace on fast roads. Clearance for tyres up to 32C also gives you scope to adjust the tyre setup to suit your riding.
Dura-Ace Di2 Performance
Shimano Dura-Ace Di2 provides electronic shift control, paired here with a Classified 12-speed cassette and Rotor Aldhu Carbon chainset. Hydraulic disc braking provides the stopping power and control expected from a modern race bike.
DT Swiss ARC 1100 Carbon Wheels
The Reacto One rolls on DT Swiss ARC 1100 Dicut DB 65 carbon wheels, complementing the aerodynamic focus of the frame. The tyre setup combines a Continental Aero 111 700 x 29C at the front with a Continental Grand Prix 5000S TR 700 x 30C at the rear.
Aero Cockpit and Contact Points
Merida Team CW Aero components create a clean, performance-focused cockpit, while the Reacto V S-FLEX seatpost and Prologo Nago R4 PAS saddle complete the contact points.
Who It’s For
