World Cup tested geometry meets high end alloy reliability. The new AIR 9 in hydroformed alloy benefits from the same decade of refinement and testing as does the entire Air 9 Family, while representing NIner’s most economical racing option. Riders benefit from years of hardtail experience with the unique ride quality of a high end alloy frame.
This version of our alloy hardtail integrates hydroformed tubing throughout. More than a cosmetic feature, hydroforming allows us to shape tubes, control wall thickness and optimize strength and stiffness in key areas. This customization creates perfectly tuned frames with precise ride characteristics – in other words, ideal ride feel. You will find hydroforming in the toptube, downtube, headtube, chainstays and seatstays.
Bottom line? A light, stiff frame with better ride feel and improved steering results in better power transfer and an overall efficiency improvement. In other words, the updated Air 9 will win more races.
These introductory builds are lovingly curated to deliver the most bang for the starter buck. The 1-Star Build is a popular choice for high school racing and great for a first Niner because it's riding, not frills, that ignites passion for the trail.
