BIG NINE 700

Features BIG NINE 700

• 

  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.

• 

  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.

• 

  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.

• 

  DOWN TUBE EXIT

  DOWN TUBE EXIT is a feature seen on some of our frames with internally routed cables. By slightly overlapping the downtube where it connects to the bottom bracket, it leaves a small space that allows cables to exit easily. This means they are easily accessible for routine maintenance or replacement, but it prevents excessive movement and noise that can cause wear and distraction.

• 

  SMART ENTRY

  Many of our frames offer internal cable routing, where the gear and brake cables are run through the frame for maximum protection and a clean look. Some internally run cables can rattle when riding over uneven surfaces, but our SMART ENTRY system prevents this from happening. Cables, housings and brake hoses are clamped under tension to prevent noisy cable movement. All inlets are completely interchangeable to deal with any kind of cable or wire.

• 

  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.

• 

  12-148 THRU-AXLE BOOST

  'Boost' hubs are 6mm wider and therefore the spokes run flatter, this results in a stiffer and stronger wheel. Especially with 29" and 650b+ wheels and in combination with a thru axle this is a big step forward. The chain-stay can also be made shorter because the bottom bracket is also wider and the chain line is moved outwards. This makes the bike even stiffer and more agile.
