2020 Niner RKT 9 RDO 4 Star - SM

2020 Niner RKT 9 RDO 4 Star build. This thing is a rocket ship and great for technical XC racing. It's a great trail bike too. I rode this bike at Leadville the last two years and its a great bike for that too. The XT derailleur clutch went out on me during the 2022 Leadville 100, so it has a brand-new XT derailleur. Bike is in great condition. There are some scratches from riding off road on the carbon but nothing that compromises the integrity of the carbon.
