Niner ROS 9 Hardtail

What makes the ROS 9 tick?

Keep It Steel, Stud. The 4130 Cro-Mo tube set of the ROS 9 is the trusted standard for durability and ride quality. Following the lines and design language of the SIR 9, these tubes have been beefed up to handle the abuse the ROS 9 is designed to shrug off. The super-short chainstays provide a lofty front end feel while the slack HT angle keeps the front end composed at Mach Loony speeds. A neutral BB height can be made low or high to slay YOUR trails by positioning the BioCentric 2 where it will do the most good.
