Mountain biking is all about exploring new trails and seeing sights you would never be able to see from the road. With a trail bike, you’ll be able to efficiently climb hills and descend down steep and technical terrain. The Niner Jet 9 RDO 4-Star Bike brings cross-country efficiency to trail bike versatility. It blends the best characteristics together for an ultimate trail bike. The RDO carbon fiber frame uses 120mm of travel on the rear and 130mm of travel on the front. The frame features full sleeve cable guides for easy cable installation, CVA suspension that is supple yet stable, and one bottle mount.

The 4-Star version of the Niner Jet 9 RDO comes with a Shimano XT M8100 12-speed drivetrain. This includes a cassette that has a hill-crushing 10-51T gear range that makes climbing and pedaling through rough terrain a breeze. The Shimano XT M8120 hydraulic disc brakes provide confidence-inspiring stopping power so you can descend under control. DT Swiss XM1700 wheels are paired with Schwalbe tires that can be set up tubeless for a smoother ride, better traction, and fewer flats. With the KS LEV Si dropper post, you’ll be able to quickly lift and lower your saddle with the press of a lever.
