Hardtail mountain bikes accel when it comes to trail and XC riding. These types of bikes climb more efficiently and roll quickly on flatter terrain. The Niner Air 9 2-Star Bike is a lightweight and highly durable mountain bike hardtail that has a hydroformed and welded aluminum frame. The frame is optimized for 120mm of travel on the front making it perfect for trail riding. The Air 9 is also compatible with wider 29" tires and 27.5+ tires.
The 2-Star version of the Air 9 comes with a SRAM NX Eagle drivetrain. With the SRAM Eagle drivetrains, you'll get a 12-speed cassette with an excellent 11-50-tooth gear range that makes climbing a breeze and riding in rough terrain much easier. SRAM Level hydraulic disc brakes provide exceptional braking power so you can descend confidently. The Niner alloy rims and Maxxis tires are tubeless-ready for a smoother ride, better traction, and fewer flats.
