There’s a new bike in town and it’s built to last, not let you down. When you’re spinning up steep climbs, bombing down the backcountry and grinding out the final miles as the sun sinks into the horizon, you need a bike you can trust. A comfortable, capable, hand-built bike made from proven, air-hardened, heat-treated steel. That’s right, steel. Because Steel Is Real and it’s fully optimized in the SIR 9.

The classic steel fame construction gives you the comfortable, durable, capable, "ride hard, put away wet" mentality that you have always wanted in a frame. To make it even more capable Niner strapped a 120mm fork up front, added no fewer than 18 threaded mounting bosses, and provided clearance for up to 29 x 2.4' tires so that you can go farther and stay out longer.

Features:

  • Reynolds 853 steel frame construction because "steel is real"
  • No fewer than 18 mounting bosses for bags, racks, bottles, and more
  • Biocentric 30 bb gives you the freedom to run whatever drivetrain you desire
  • Trail ready geometry provides a longer top tube and slacker head tube for more stability at speed
  • Integrated dropper post routing for a clean setup
  • Tire clearance for up to 29 x 2.4" or 27.5+ tires
