Niner took the already rowdy ROS 9 and fattened it up for your pleasure. It shrugs off abuse with a frame built out of tough 4130 chromoly and features Niner’s popular long-travel hardtail geometry that begs to carve and huck all the way home. It has the same unwavering 142 x 12mm through-axle dropouts out back with simple inserts for easy setup with both single speed and geared options. And, it clears 3.0-inch rubber, making the ROS 9 Plus versatile as a four-season ripper, extra-gnarly trail tamer, and all-around plaything.

Niner built a chromoly fork for this beast that combines the benefits of a tapered steerer, a 15mm thru-axle, and a relatively short axle-to-crown length. All these features mean you get a stable and predictable front end that climbs well, avoids rotor rub, and precisely carves out whatever line you choose. To make sure you can have your ROS 9 Plus just how you like it, Niner included all the same bells and whistles as on the standard ROS 9 frame, like internal dropper post routing, removable front and rear derailleur hangers, and integrated MRP bash guard mounts on the bottom bracket shell.

Niner’s ROS Plus 3-Star XT 1x gives you the tools you need to back up your boasts. The svelte Shimano XT 1 x 11-speed drivetrain gives you a generous range of gears with a monster cassette and XT Shadow Plus rear derailleur that team up to make a clean, lightweight drivetrain that will keep you in gear so you can drop the hammer, not your chain. While we’re on the subject of dropping, when you’re losing elevation like a lead balloon, you’ll be thankful for the ruthless Shimano XT brakes that slow your marginally-controlled self, so you rail the corner and avoid any cacti cartwheel. The Stan's wheelset features Neo hubs and 52mm-wide Hugo rims that let the Vittoria Bamboloni tires spread out all over the trail for unnerving traction whether you're going up, down, or 'round and 'round. Niner threw a KS dropper post on the ROS 9 Plus, allowing you to instantly switch spirit animals from mountain goat to downward dog so that you can make the most of every section of trail. Make your life a little better each day on the ROS 9 Plus 3-Star.
