CATEGORY HIGHLIGHTS

Lightweight 6066 triple butted and hydroformed aluminium with NACA fastback aerodynamic tube profiles and smooth welding, internal cable routing and integrated seat clamp. Tapered head tube and full carbon fork for precise handling

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

The REACTO is available in both caliper and disc brake options. We use direct mount caliper and flat mount disc brake standards (with our disc cooler 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.

A forged aluminium part under the front and 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.

Our high-performance carbon models with the CF4 frame feature a completely integrated Vision Metron 6D cockpit designed by MERIDA, to improve aero-dynamics and hide the Di2 junction box. The integration also provides a very clean, organic and modern appearance.

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 great level of comfort amongst other aero bikes.

Technologies

IMAGE

PROLITE 66 TRIPLE BUTTED ALUMINUM

Our proven high-end aluminium (6066) is extremely light and durable. Using triple butted wall thicknesses and hydroforming technology, we can tune the aluminium tubes to give the best possible stiffness to weight ratio.

IMAGE

HFS - HYDRO FORMING SYSTEM

Tubes are inserted into negative moulds and a hot emulsion of water and oil is forced through at pressure, enabling them to be formed into complex shapes.

IMAGE

X-TAPER HEADTUBE

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.

IMAGE

SMOOTH WELDING

Sometimes called ‘double pass welding’, a second pass over the weld gives a clean organic look to the frame. At first glance, you will be convinced it is carbon.

IMAGE

INTERNAL CABLE ROUTING

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.

IMAGE

TFS - TECHNO FORMING SYSTEM

Technoforming is a mechanical forming process, shaping the tubes by using negative moulds, at times combined with an internal metal core. 

IMAGE

NACA FASTBACK PROFILE

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.

IMAGE

INTERNAL CLAMP

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.
