    To reduce production and delivery times, we are sometimes forced to make last-minute specification changes. Please be aware that those changes might not be reflected on these product pages and images.


    To offer maximum control and braking performance, the new REACTO comes equipped with disc brakes throughout the range. We use flat mount disc brake standards in combination with our 'Disc Cooling' technology at the front and rear for the best braking performance. A flat mount rear caliper is mounted on the chainstay which is better for dissipating braking forces but also keeps it protected inside the rear triangle.

    Our high-performance carbon models with the CF5 frame feature a completely cable integrated Vision Metron 5D ACR carbon cockpit, improving aerodynamics and offering a super clean silhouette and cockpit area. The CF3 models with electronic shifting feature a two-piece aluminium cable integrated cockpit consisting of a Vision ACR SMR stem combined with a MERIDA EXPERT CW handlebar. All three cockpit options provide a very clean, organic and modern appearance.

    With aerodynamic optimisation at the fork, seat stays and a cable integrated cockpit the new REACTO offers even better values than its already class-topping predecessor.

    The 12 mm bolt through axles for greater wheel stiffness and precise disc alignment when replacing wheels. The custom axle lever is removable and has a 4 mm Allen key included, so, for example, stem and seat post clamps can be tightened and loosened.

    All models feature a full carbon fork with a tapered steerer to give precise, confidence-inspiring steering. All SCULTURA Alloy and CF2 carbon models feature a ‘regular’ 1 1/8" to 1 1/2" taper. The high-end SCULTURA CF4 frame has a slimmed down front profile and uses a 1 1/8" to 1 1/4" taper, the new REACTO frames a 1 1/2" to 1 1/4"taper.

    A forged aluminium part under the front and/or rear disc brake caliper draws heat away through CNC-milled cooling fins giving 35 % less heat build-up and faster temperature reduction for a stable braking performance.

    Comfort has always been a key feature of the REACTO. Many aero bikes suffer from a harsh ride due to the larger tube sections and seat posts. Not so on the REACTO, where our profiled seat post behaves like a conventional seat post providing a significant level of comfort amongst other aero bikes.




    Our X-Tapered headtube offers the space for a tapered fork to be fitted. Tapered forks offer superb stiffness and precise and deliver confidence-inspiring steering.



    Cables are routed through the frame, entering and exiting through smooth sockets. The bike looks neat, whilst the cables are protected from moisture and dirt.



    To protect the integrity of carbon frames, the fibres are bonded together with an epoxy resin with added nano particles, increasing impact resistance by up to 40%.



    When creating the individual carbon elements, an inflatable bladder is used to ensure there are no wrinkles inside the tube as these can add weight and create weakness. This results in a lighter, stiffer and stronger frame.



    The aerodynamics are based around a NACA0028 teardrop profile (National Advisory Committee for Aeronautics) which is truncated. Air moves around the tube as though the missing rear section of the teardrop were still there, saving weight by using less material.



    A forged aluminium component under the front and/or rear caliper allowing heat to dissipate through CNC-milled cooling fins. Tests show that temperatures are reduced by around 35 % and cooling times are shortened, optimising the performance of the brake.



    Designing WorldTour bikes is similar to Formula 1: apparently nondescript details can result in saving split seconds. Integrated seat-post clamping minimises turbulence at the top tube.



    MERIDA designed headsets that allow all control cables to enter the frame through the headset, creating a clean and uncluttered look, without making structural changes to the frame. Depending on the model, the cables are run completely internally (including bar and stem) or semi-integrated where the cables enter the frame underneath the stem.
