Niner SIR 9 Frame

Real Is Steel

"Steel is real" is what you'll hear people who ride steel-framed mountain bikes say as they descend from the tops of the tallest mountains and flow over the fun single tracks. Though the frames may be slightly heavier than aluminum and carbon, steel frames are rugged, reliable, and incredibly comfortable over the roughest trails. The Niner SIR 9 Frame is here to take you on your next adventure. The Reynolds 853 Steel Frame uses 120mm of travel on the front and is compatible with 29x2.4" tires or 27.5x3.0" tires. The Trail Country geometry blurs the lines between modern trail bike geometry and traditional cross-country geometry making this perfect for long pedaling rides, stiff climbs, and extended descents. The frame features 18 mounting points so you can use this as your bikepacking bike, internal dropper post routing, and a lifetime frame warranty.
