There’s a new bike in town. It’s built to last and not let you down.When you’re spinning up the steeps, 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 SIR 9 is strapped with a 120mm travel FOX suspension fork, perforated with no fewer than 18 threaded, reinforced mounting points, clears 29x2.4” (or 27.5x3.0”) tires, and offers easy options for geared or singlespeed drivetrains. No excuses - pack an extra jacket and a PBR, go farther, and stay out longer.
Blurring the lines between modern trail bike geometry and traditional cross-country geometry, the SIR 9 occupies a niche we lovingly call “trail country.” If you’re doing a combination of long pedaling rides, stiff climbs, extended descents, and spicy technical sections, you’ll love what Niner have done here. “Trail country” geometry translates to modern trail manners when you need them most, with no sacrifice of efficiency or agility.
Features:- This 4-Star SIR 9 is dressed for success with a light, stiff FOX 34 120mm travel suspension fork, Shimano XT drivetrain, and DT Swiss M1700 wheels. No excuses - get out and ride!
