NINER AIR 9 RDO 4-STAR BIKE 2021

LIGHTER AND BRIGHTER

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 RDO 4-Star Bike is lightweight, stiff, efficient, and compliant. It is great for cruising the trails, shredding the singletrack, and getting riders to the podium. It has an RDO carbon fiber frame that has internal cable routing and is single-speed compatible. The frame features integrated frame protection and tire clearance for up to 2.4″ tires.

The 4-Star version of the Niner Air 9 RDO comes with a Shimano XT M8100 drivetrain. This includes a cassette that has a hill-crushing 10-51T gear range that makes climbing and pedaling through rough terrain much easier. Shimano XT M8100 hydraulic disc brakes provide superior stopping power so you can descend with confidence. With the DT Swiss XR 1700 Spline 25 wheels and Schwalbe tires, you’ll be able to set everything up tubeless for a smoother ride, better traction, and fewer flats.
