The first trail-bike style, short chainstay, big tire hardtail is all Niner and all fun. Based on our wildly popular long travel hardtail geometry, the ROS 9 Plus delivers miles of shreddy riding. The bike features short chainstays for a playful feel (437mm at 9 o’clock BB position), while accommodating 3.0 tires for the ultimate in traction and plushness. The 29 Plus platform is the most versatile of the big-tire options – great for off season riding and a functional daily driver – and now we’ve made the most fun version of this platform available.
The ROS 9 Plus is made with 4130 ChroMoly, the go-to material for high abuse applications since the early days of off-road bikes. The tubeset offers the durability and ride quality you want for rowdy rides. Complemented by custom forged 142x12 maxle compatible dropouts in the rear, the frame is designed to resist twist under heavy pedal loads and when cornering and descending. The frame also features high quality details such as internal and external dropper routing, removable cable guides and custom forged seat and chainstay bridges.
A 2-Star Build is designed to get Niner owners out on the trail, happy in the knowledge they got a great bike at a great price. Perfect for riders who desire a taste of how quality components can transform the riding experience
