REACTO 400

Features REACTO 400

• 

  PROLITE 66 TRIPLE BUTTED ALUMINIUM

  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.

• 

  CARBON FORK

  Starre carbon voorvork, eventueel met carbon stuurbuis. Een Merida carbon voorvork biedt uitstekende demping van vibraties en tegelijkertijd een hoge (laterale) stijfheid voor perfect rem- en stuurgedrag.

• 

  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.

• 

  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.

• 

  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.

• 

  NACO 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 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.

• 

  DI2 READY

  Shimano's Di2 electronic shifting system offers fast, smooth and reliable shifting. In particular, in the road world, it has proven itself as the primary choice when top performance is at the top of the agenda. With that in mind, we have a broad selection of performance road frames that are Di2 READY and can accommodate the electrical cable, battery and other little tweaks that the system requires.

• 

  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.
