You will find hydroformed tubing throughout Niner’s line up – the Air 9, E.M.D. 9, Jet 9, R.I.P. 9 and W.F.O. 9 all incorporate proprietary hydrofomed tube shapes. The effect of this upgrade goes much further than appearance. Hydroforming allows us to shape the tubes and optimize strength and stiffness in key areas, giving us the ability to create beautifully tuned frames with the precise ride characteristics we seek for every application. In testing, frames incorporating hydroformed tubing put up stiffness numbers much higher than those with old-style round tubing.
  • The shape of a tube is as important now as the material it is made from. Shaping has a huge effect on the way stress is distributed across and around a tube. Controlling the stress distribution enables us to use less material while maintaining or even increasing the frame strength.
  • Shaped tubing is found in many frames. It is important to be aware that how a tube is shaped can change the quality of the results. The least expensive method for shaping a tube is via mechanical forming. In this process, tube shapes are

  • Shaped tubing is found in many frames. It is important to be aware that how a tube is shaped can change the quality of the results. The least expensive method for shaping a tube is via mechanical forming. In this process, tube shapes are
  • achieved by manipulating a straight gauge tube using mandrils, dies and, tube bending equipment. This approach has limits, particularly when it comes to tube bends and tube butting (wall thickness). To contrast, Niner uses a multi stage hydroforming process - a straight gauge tube is butted and mechanically formed in preparation for the hydroforming process. Once the initial tube geometry is achieved, the tube is fully enclosed in a die, then pressurized with hydraulic fluid. This causes the aluminum to expand, obtaining the shape of the die. This process allows better control of wall thickness and more flexibility in cross sectional shaping over mechanical forming.
  • A massive, hydroformed downtube paired with tapered headtube, as well as a significantly larger diameter toptube, contributes to a much stronger frame with superior steering and power transfer.
  • Chainstays, seat tube and seatstays also benefit from hydroforming, via controlled wall thicknesses for increased butting profiles . This translates to rear triangle that are tuned for stiffness, strength and vertical compliance – in other words, ideal ride feel.
