Because the racing bug doesn’t choose who it bites, Niner offers the AIR 9. With World Cup-tested mountain bike race geometry and lightweight hydroformed aluminum, this privateer-priced frame has the design to win. Hydroforming allows Niner to control the shape of the tubes and wall thickness to optimize strength and stiffness in key areas. The rigid sides of their signature down tube and top tube shapes maximize torsional stiffness, with a buttery smooth ride quality achieved via the flat sections on each tube, which act like leaf springs. A PressFit 30 bottom bracket and 142 x 12mm thru-axle complement and magnify this efficiency, ensuring lightweight stiffness where power might otherwise be lost to frame flex.
