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 have taken on a short travel cross country geometry, whereas the ROS 9 Plus slackens the headtube and shortens the chainstays to make this a true fun factory of a bike. The tire clearance can accommodate 3.0 tires which bolster traction and plushness to previously unknown levels. The frame is constructed from 4130 ChroMoly steel which lives up to its reputation as 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.
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 fork features a 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 cable guides, Biocentric II Bottom Bracket and custom forged seat and chainstay bridges. With a BioCentric II bottom bracket, the frame is single-speed capable. If 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 chain stays and 3.0 tires limit the ROS 9 Plus to 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 mounts for a custom XCG Bash Guard to protect the precious chainrings from rocks, logs and other trail impacts.
The ROS 9 Plus NX Jenson bike features a formidable blend of components that deliver a high level of functionality and eye for substance over style. You can think of the ROS 9 as a bike with ADD whose only concern is going out and having fun and not thinking about anything else. For this reason, Niner paired it with a SRAM NX drivetrain which brings single ring living to this hyper bike, eliminating the front derailleur and a shifter to ensure the focus remains on having a blast. The Shimano SLX brakes deliver the stopping power and superior modulation of hydraulic disc, while keeping the cost minimal.
The Stan's No Tubes Hugo wheelset features a 52mm wide rim on the outside and 49.9mm wide on the inside. The wheelset weighs 630 grams and is drilled for Schrader valves for ease of inflation. It features a double wall section in the middle and it has independent drop channels on each side for easy inflation and mounting. Niner and Race Face take on the cockpit duties with an alloy seatpost, handlebar, and stem.
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 goodtime.
