The Niner ROS 9 is a versatile 4130 Cro-Mo steel frame with aggressive geometry which brings modern technology (oversized headtube, internally routed dropper post routing, and 12x142mm rear dropouts) to a frame that will last a lifetime.
The ROS 9 borrowed the SIR 9’s rear dropout design to allow 12x142mm rear hub configurations while still supporting the replaceable alloy derailleur hanger and allowing more surface area for a full weld around the entire end of the chain and seat stays ultimately creating a stiffer rear end. With a BioCentric II bottom bracket, the frame is single-speed capable. If running this as a multi-speed, the BB height can be adjusted when using a BioCentric II bottom bracket to fit this bike to your specific needs.
The ROS 9 features super-short chainstays and a slack headtube angle to better the handling at high speeds. The front and rear derailleur mounts are removable/replaceable. The R.O.S. 9 accepts internal and externally routed dropper posts with an alloy cover to block the port and keep out any debris if you choose not to use it. The ROS 9 also features tabs under the bottom bracket shell to mount a proprietary MRP XCG bash guard (sold separately).
