Niner WFO RDO 4-Star Bike 2021

A Legend Reborn

When it comes to enduro riding, you’ll want a mountain bike that is durable, nimble, and can roll over any obstacle in your path. The Niner WFO RDO 4-Star Bike is back and ready to conquer the enduro course. It is reborn with 170mm of stable CVA suspension, a 180mm travel fork, adjustable geometry, increased frame stiffness, and Niner’s signature RDO carbon frame. The frame features full sleeve cable guides for easy internal cable routing and integrated frame protection.

The 4-Star version of the Niner WFO 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 demanding terrain a breeze. Shimano XT M8120 hydraulic disc brakes provide excellent stopping power so you can descend with confidence. DT Swiss EX 1700 Spline 30mm 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.
