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 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.

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/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.

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 significant level of comfort amongst other aero bikes.

PROLITE 66 TRIPLE BUTTED ALUMINUM

When creating high-end aluminium frames, we use our proven PROLITE 66 (6066) aluminium, as it is incredibly light and durable. In addition, it works exceptionally well with our hydroforming technology, allowing us to create complex shapes, featuring triple butted wall thicknesses, an almost carbon-like appearance and the best possible stiffness-to-weight ratio. While lesser alloys might be cheaper, it is the ideal choice for high-performance bicycle frames.

HFS - HYDRO FORMING SYSTEM

‘C-Mount’ equipped bikes have the fixing points for a rear rack already integrated (some bikes require model specific rear rack), making fitting fast, simple and reliable.

X-TAPER HEADTUBE

Steering precision is vital to safe and confident handling, and the X-TAPER HEADTUBE allows us to significantly boost this precision. A larger headset diameter at the bottom paired with a smaller one at the top helps to deal with the strains modern riding and equipment can put on the headtube, all without adding unnecessary weight. It allows tapered forks to be fitted with ease and delivers precise and confidence-inspiring steering.

SMOOTH WELDING

This is a process we use to give a nice flat finish to our welds instead of the scaled, 'stack of coins' effect TIG welded joints often have. The welder uses the welding torch to go over the joint twice, helping to smooth out the filler material. It takes a lot of skill to do this, but it delivers strong and smart-looking frames that have the appearance of a carbon fibre frame at first look.

INTERNAL CABLE ROUTING

On the majority of our frames, we run the gear and brake cables and hoses through the frame. The cables enter and exit the frame through smooth sockets, or we use one of our other systems like SMART ENTRY or WIRE PORT to be routed through. Running the cables inside the frame protects them from the elements, gives a clean and neat look and can offer aerodynamic advantages.

TFS - TECHNO FORMING SYSTEM

Manipulating the tube shape and thickness greatly impacts the appearance, weight and functionality of our aluminium frames. One technology that allows us to do that is TECHNO FORMING, where plain aluminium tubes get mechanically formed by using an external form and an internal metal core. The result, beautifully shaped tubes with varying wall thickness, ready to be used to create our technoformed aluminium frames.

NACA FASTBACK PROFILE

This is a special kind of tube shape that helps reduce aerodynamic drag while also helping to reduce weight. It’s based around a teardrop profile that was originally developed in the aeronautical industry, but the rearmost portion of the profile is cut short. This reduces the amount of material needed to make the tube, but air still flows around it just as well, giving all the aerodynamic benefits but at a lower weight.

INTERNAL CLAMP

When every second counts, the smallest of details can make the difference between winning and losing, so we look at every aspect of our frames to make them as sleek as possible. By using a seat post clamping mechanism that secures the post with a wedge inside the frame itself, we minimise the turbulence and potential drag while keeping post height adjustment simple, giving a frame that is more aerodynamic and also better looking.
