Niner introduces the versatile ROS 9, a 4130 Cro-Mo steel frame that can be run as a single speed - using Niner's own super light BioCentric II bottom bracket - or a geared bike with a replaceable derailleur hanger. This frame is built for abuse and the downhill spec geometry makes it a blast to ride. Niner designed the ROS 9 to be a burly trail ripper with super-short chainstays and a slack head tube angle that can accommodate 120mm to 140mm travel fork. Once again, Niner's attention to detail can be seen on every aspect of this frame. The unique dropout design allows 142x12 Maxle use and accommodates a stout alloy derailleur hanger or a single speed insert for a perfectly clean look. The custom butted 4130 Cro-Mo main triangle uses size specific tubing with exceptionally clean welds and is drilled for internal dropper post routing and a proprietary MRP XCG bash guard. Other details include custom drawn S-bend chain stays and seat stays, an oversized tapered headtube and a stainless steel head badge. Essentially, the ROS 9 is the perfect all mountain hardtail machine, made to Ride Over Shit (ROS).

Master the mountain using the Fox 34 Talas 29 140 CTD-ADJ FIT 15QR 1.5T. The innovative CTD dial provides three distinct travel settings: Climb, Trail, and Descend making it easier than ever to dial in your fork for your current terrain. The Climb mode is obviously the firmest setting, offering the greatest pedaling efficiency. The Trail mode offers moderate low-speed compression setting is activated for an optimal blend of pedaling efficiency and bike control on variable terrain. Trail mode activates to full-open for maximum control and plush performance on steep, aggressive descents. If you're building a full suspension rig, this same CTD is paralleled in the rear shock, making it incredibly easy to balance the ride characteristics of the bike as a whole. CTD lever is easily in reach, at the crown of the fork. Travel adjustments are now easier and quicker with the 2-position, crown-mounted Talas lever that instantly changes travel between 140 and 110mm to improve climbing ability. The re-tooled FIT RLC damper reduces oil volume and lightens the fork, while a special head seal prevents dirt penetration for instant small bump response. 140mm travel.

For use with Sram cranksets

While other systems rely on side loading the bearings to eliminate play (which causes premature bearing wear), the SRAM GXP bottom bracket system is different. The GXP system positions the left side bearing between the spindle and the left crankarm, while allowing the drive-side bearing to float axially on the spindle, thereby eliminating the necessity to side-load bearings during adjustment. GXP's design allows greater variation in BB shell alignment, maintaining precision and performance regardless of thread and construction irregularities in the frame. Installation is simple: once it is tightened to the proper specifications you are ready to roll with a worry free bottom bracket employing two bicycle specific cartridge bearings and eight seals for a smooth and long lasting ride.
