NINER RKT 9 RDO RS 4-STAR BIKE 2020
RACE SPEC ROCKET
Cross-country bikes need to be lightweight, fast, and able to dominate the terrain. If you're in an XC race, you need every advantage you can get. The Niner RKT 9 RDO RS 4-Star Bike is a lightweight XC race bike with 90mm of travel on the rear and 100mm of travel no the front. The carbon fiber frame uses Niner's CVA (Constantly Varying Arc) suspension design that is built to be supple yet stable, controlling unwanted suspension movement with calibrated anti-squat, yet remaining active while climbing and descending. The frame is stiff, efficient, light, and highly durable.
The 4-Star version of the RKT 9 RDO RS comes with a 12-speed Shimano XT M8100 drivetrain. The cassette has a hill-crushing 10-51-tooth gear range that makes climbing a breeze and riding in rough terrain much easier. When it comes to descending, the Shimano XT hydraulic disc brakes provide confidence-inspiring stopping power. The DT Swiss X1900 Spline wheels are paired with Maxxis tires. Both are tubeless-ready so you can ditch the tubes and drop the tire pressure for a smoother ride, better traction, and fewer flats. With Fox suspension on the front and rear, you'll have an exceptionally smooth ride everywhere you go.
