If you’re looking for the lightest mountain bike possible, you’ll want to get a hardtail. Hardtails feature suspension on the front making them excellent climbers and fast on the flats. The Niner Air 9 3-Star Single-Speed LTD Bike is an aluminum hardtail with the DNA of a trail bike. It is great for cruising the trails, shredding the singletrack, and getting riders to the podium. It has a hydroformed aluminum frame that has external cable routing and is single-speed compatible. The frame features “trail country” geometry and tire clearance for up to 29 x 2.4″ or 27.5 x 3.0″ tires.

The 3-Star Single Speed LTD version of the Niner Air 9 comes with a simple single-speed drivetrain. This allows riders to focus on what is most important: the ride. Shimano XT hydraulic disc brakes provide superior stopping power so you can descend with confidence and under control. With the Niner Alloy wheels and Schwalbe tires, you’ll be able to set everything up tubeless for a smoother ride, better traction, and fewer flats.
