NINER SIR 9 FRAME 2021
BECAUSE STEEL IS REAL
The frame you use for mountain biking will largely determine what style of riding you'll be able to do out on the trails. With a trail bike, you'll be able to climb efficiently and descend with confidence on those rougher hills. The Niner SIR 9 Frame is made from rugged, reliable, and comfortable Reynolds 853 steel. The frame is optimized for 120mm of travel on the front, is compatible with 29 x 2.4" or 27.5 x 3.0" tires, can be used geared or single-speed, and has "trail country" geometry which blurs the lines between modern trail bike geometry and cross-country geometry. The frame features integrated dropper post routing and has multiple mounting points for racks, fenders, bottles, and frame bags.
Features
- Wide tire clearance for up to 29 x 2.4" or 27.5 x 3.0" tires
- 853 Reynolds steel frame is rugged, reliable, and comfortable
- Multiple mounting options for racks, fenders, bottles, and bags
