Niner JET 9 RDO 3 Star XT Bike

The Niner Jet 9 RDO is a full suspension, carbon 29” masterpiece that Niner has created. Niner’s carbon is strong but provides a supple ride. The swooping curves and strong lines of the frame were developed through the testing of their competitors’ products. Niner determined the proper shape and thickness for their tubing in order to achieve maximum performance. They have measured performance in strength, stiffness, and damping. Niner is very confident in the quality of their carbon; therefore, they have attached a five year warranty.

The Jet 9 RDO features Niner’s patented CVA suspension. This is the only suspension created for the sole purpose to be used on 29” bikes. In other words, they did not modify suspension that was created for a 26” wheel. The CVA suspension was created with the goal of efficiency. Due to the location of the lower pivot bolt, chain torque effectively isolates and cancels out the forces acting to create inefficiency in pedal stroke. The rider will be able to use all three chainrings. CVA has excellent small bump compliance, to ensure that your ride is smooth as well as fast.

The Niner JET 9 RDO XT Bike features an impressive component spec that is ideal for racers and trail riders alike. Fox is well known within the industry for producing high-end suspension components that are easy to setup and use. Therefore, it was only logical that Niner chose to incorporate the Fox 32 Float CTD fork with one of their leading cross-country race frame. The Fox 32 Float CTD fork features 100mm of smooth Kashima coated travel with Trail Adjust for eating up those small trail vibrations. The 15mm axle and tapered head tube ensure the front end is stiff, helping maintain excellent steering, especially when riding winding single track or switchbacks. Shimano XT is known as the workhorse of the brand. Shimano XT components are built to be tough, without tipping the scale. The Shimano XT 10 speed drivetrain provides smooth, accurate, and fast shifting. There will be no sloppy shifts with Shimano XT. Stan’s NoTubes Arch EX wheels are heavy duty yet lightweight wheelset that will take a beating without weighing you down. A Niner signature carbon cockpit rounds out this build, making it the perfect blend of quality, weight, strength, and speed.

    Comments about Niner JET 9 RDO 3 Star XT Bike:

    Great all around ride. Suspension is solid until you get into the big bumps and the thing climbs like a goat. If you're racing I'd put a 100 on the front or for more versatile riding go 120.
