WHAT MAKES THE ROS 9 TICK?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 headtube 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 II where it will do the most good.

Construction details abound We borrowed the unique dropout design we developed for the SIR 9 to allow 142x12mm Maxle use and house the stout alloy derailleur hanger. The dropout designs allow the chain stays and seat stays to be welded at any angle and provide far more surface area for a full weld around the tubes end. The front derailleur hanger is removable with an alloy cover. Internal dropper post routing is optional, another alloy cover closes the port if you choose not to use it. Externally routed dropper posts utilize mounts under the top tube. Tabs under the bottom bracket shell accept an proprietary MRP XCG bash guard for optional extra protection. Full-housing cable routing for front and rear derailleurs using Niners bolt-on double housing clamps along top and down tubes complete the versatility. If you dont need the guides, take them off and enjoy the clean look of the frame in singlespeed mode.

OVERSIZED HEADTUBEThe oversized headtube of the ROS 9 allows the use of tapered fork steerer tubes that measurably reduce fork deflection, which means your Niner tracks straight and true. The full spectrum of riders from xc racers to all mountain shredders benefit from these features which is why we incorporate the technology in all our new frames. The ROS 9 Lets you take full advantage of increased steering precision as you get yourself into trouble.

The hardtail for riders that dont like hardtails. No twitchy high-posting around features you would hit on your real bike. No need to back off because your XC racing head angle prevents solid roosting. The ROS 9 wont judge your lines - it lets you write checks your skills might not be able to cash, and what is more exhilarating than that? Short chainstays, slack head angle, and oversized headtube nourish these Roots of Steel - all with the ability to tweak the geometry via the BioCentric II. Run this rig singlespeed, 1x or fully geared with a front derailleur if you roll that way. Remove the cable guides and front derailleur mount if you dont. Stealth routing for the dropper post keeps the ROS 9 fresh and clean. Sorry, the ROS 9 is not compatible with heart rate monitors or training plans but it will certainly earn you some PRs when you do your part keeping the rubber side down. Ride Over S*!t The new ROS 9 injects hardtails with a huge-ass dose of fun.

BIO-CENTRIC II BOTTOM BRACKET SYSTEMThe Niner BioCentric II makes adjustments easy across a wide range of gears and eliminates the need for adjustable dropouts, giving the cleanest possible solution for singlespeed use. No bolt on hubs, no chain tensioners cluttering your ride, no brake adjust-ments with gear changes. Additionally, BB positioning allows fine-tuning of geometry. Want shorter chainstays? A lower BB? Steeper or slacker seat angle? Its all achievable with the BioCentric II.

Greater Range - The BioCentric II offsets the bottom bracket spindle 8.5mm from center, offering greater range of adjustment compared to a traditional EBB setup. More offset is a boon when changing gears without having to change chain length and it al-lows riders to make more noticeable changes to frame geometry. Reliable Function - Traditional EBB units are held in place with set screws that can become difficult to finely adjust over time, or ex-pansion wedges that can deform the bottom bracket shell of the frame. Split bottom bracket shells that clamp an EBB can stretch or ovalize. The Bio-Centric II avoids these troubles by using two bolts to apply a clamping force on the outside edges of the BB shell, eliminating the possibility of ovalizing or indexing the shell.

For riders who fall between sizes we recommend sizing down for a more maneuverable ride or sizing up for more stability. The best way to determine which size is for you is to test ride a Niner at one of our dealers or demo events.
