Niner Ros 9 Plus Frameset 2015

Niner Ros 9 Plus frameset 2015

What do you get when you cross a 29er with a fat bike? The answer is the Niner ROS 9 Plus! By using the insanely popular ROS 9 long travel hardtail geometry to draft up the blueprint for the ROS 9 Plus, Niner has introduced the first trail-esque rigid 29+ shredding machine.

Many of the 29+ Bikes on the market are designed around a short-travel cross country geometry, whereas the ROS 9 Plus takes it in a different direction. Niner slackened the headtube and shortens the chainstays to make this a true fun factory of a bike. The frame is built for 29x3.0" tires which take traction and plushness to previously unknown levels. If you've never ridden 29+, you're destined to have a big grin on your face the moment to unleash this beast on the trail.

Niner built the ROS 9 Plus from 4130 ChroMoly steel, a bombproof material that will absorb the abuse inflicted by the most unforgiving of trails, offering the resilience and ride quality you want for unruly riding. Its razor sharp handling is augmented with a custom forged 142x12 Maxle compatible dropouts in the rear, the frame is further equipped to resist twist under heavy pedal loads and when cornering and descending. Up front, the matching tapered chromoly steel fork features a unique 15mm thru-axle and a 470mm axle to crown length to keep the front low so that you can get the best climbing position. Additionally, the ROS 9 Plus frame also features clever details that are a little less noticeable, such as internal and external dropper routing, removable downtube cable guides, Biocentric II Bottom Bracket and custom forged seat and chainstay bridges. With the included BioCentric II eccentric bottom bracket, the frame is easy to run as a single-speed if you so wish. If you're going to keep 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.

Although the short chainstays and 3.0 tires limit the ROS 9 Plus to a 1X only set up, Niner has kept the removable High Direct Mount on the seat tube for use with chain guides available for this standard. Additionally, Niner worked with MRP, to design unique mounts for a custom XCG Bash Guard to protect the precious chainrings from rocks, logs and other trail impacts.

The bottom line is, when a rowdy steel frame with a slackened headtube and chiseled chainstays meets the 29+ wheel, you get a bombproof bike that’s jonesin’ to be shown a good time.

What's in the box? From what I read, I think - Frame, Fork, Headset, Eccentric BB, Ream Maxle. Correct? What about the front maxle? I don't see any reference to it being included. Thanks
