Highlights

Superlite CF4 frame using the highest quality fibres for minimum weight (caliper version below 1050 g– M/L / disc version approx. 950 g – M/L). Aggressive pro geometry with ‘NACA Fastback’ profiled tubes and slimmed down tapered head tube (1 1/4") for superb aerodynamic efficiency and BB386 for exceptional power transfer. Caliper version runs quick release hubs, Disc version has R.A.T system bolt through axles with disc cooler technology.

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

X-TAPER HEADTUBE

Using a tapered head tube with 1 1/8" bearings in the top and 1 1/4" or 1 1/2" in the bottom creates superb stiffness and precise, confidence inspiring steering.

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

DI2 READY

Bikes/frames with the symbol ‘Di2 Ready’ are prepared for the installation of Di2 technology with battery mounting in the seat post or within the fork steerer.

IMAGE

NANO MATRIX CARBON

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%.

IMAGE

AWS

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.

IMAGE

S-FLEX

Patent pending design. Carbon is good at absorbing vibration but to increase comfort we shape the seat posts using our exclusive S-Flex design.

IMAGE

CARBON FORK

Carbon forks provide superb vibration damping and precise steering. All road bikes feature a full carbon fork; the steerer and fork blades are all made of carbon.

IMAGE

12-142 THRU-AXLE

A 142 mm wide 12 mm rear axle fixed directly into the frame increases rear end stiffness whilst simplifying wheel removal and replacement.

IMAGE

12-100 THRU-AXLE

Selected front forks use a 100 mm wide through axle 12 mm in diameter to increase lateral stiffness.

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.
