NINER TECHNOLOGY

For every model, whether it's their lightest cross country hardtail or the burliest full suspension bike, Niner considers how each angle or length will interact with big wheels to affect the finished build.

View Details >

The basic concept of the larger diameter is simple: it will keep your wheels on top of oncoming obstacles. Rather than riding IN the terrain, you'll be riding ABOVE it, gaining more control and stability on even the roughest trails.

PRODUCT DESCRIPTION

Niner ROS 9 1-Star X7 Bike

What makes the ROS 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 heat tube angle keeps the front end composed at Mach Loony speeds. A neutral bottom bracket height can be made low or high to slay YOUR trails by positioning the BioCentric 2 where it will do the most good. Construction details abound – They borrowed the unique dropout design developed for the SIR 9 to allow 142x12 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 tube’s end. The front derailleur hanger is removable with an alloy cover. Internal dropper post routing is optional, an 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 a proprietary MRP XCG bash guard for optional extra protection. Full-housing cable routing for front and rear derailleurs using Niner’s bolt-on double housing clamps along top and down tubes complete the versatility. If you don’t need the guides, take them off and enjoy the clean look of the frame in singlespeed mode.

  • 44MM OS Headtube
  • Slack and Low Geometry w/ Extra-Short Chainstays
  • BIOCENTRIC II
  • Internal Dropper Post Routing
