Following the lines and design language of the Niner SIR 9, the tubes have been beefed up to handle the abuse the ROS 9 is designed to shrug off.
ROS 9 - RIDE OVER SH*T!
The 4130 Cro-Mo tube set of the ROS 9 is the trusted standard for durability and ride quality.
Construction details abound. From the unique dropout design with 142x12mm Maxle to the sleek brake mounts, 44mm OS headtube, removable bolt-on housing guides, and removable front derailleur hanger with alloy cover, the ROS 9 is dialed.
There's something awesome about the simplicity of a hardtail...
The super-short 418mm chainstays provide a lofty front end feel while the slack 67-degree headtube angle keeps the front end composed at Mach Loony speeds.
BioCentric II enables perfect singlespeed setup and allows geometry fine-tuning. It uses two bolts to apply a clamping force on the outside edges of the BB shell, eliminating the possibility of ovalizing or indexing the shell.
The system has a 73mm BB width and is compatible with external bearing cranksets.
BioCentric II offsets the bottom bracket spindle 8.5mm from center, providing loads of adjustment.
No bolt on hubs, no chain tensioners, and no brake adjustments needed.
Tabs under the bottom bracket shell accept a proprietary MRP XCG bash guard for optional extra protection. Internal dropper post routing is optional, another alloy cover closes the port if you choose not to use it.
Fact: Zero mm of suspension is efficient in every chainring, even when you're drifting.
The new ROS 9 injects hardtails with a huge-ass dose of fun.
