More than a decade after Niners first W.F.O. 9 defined the category and set a benchmark for what a long-travel 29er could do, theyre bringing it back. The 2021 WFO 9 RDO draws on their years of 29er evolution to establish a new paradigm of unbridled, big-wheel domination. Reborn with 170mm of stable CVA suspension, a 180mm-travel fork, adjustable geometry, increased frame stiffness, and our signature RDO carbon fiber, the new generation of WFO 9 RDO is an enduro-ready brawler with the pedaling prowess to get you to the top in style.
