JET 9 RDO Mountain Bike Frameset by Niner
Ever since the RKT stepped in to take the role of the XC full-squish whippet in the Niner lineup, the JET 9 RDO Mountain Bike Frameset has been free to, ahem fly, as the brand's quintessential trial machine. Sitting right between the aforementioned Jet and the all-mountain, enduro bruiser, the Rip 9, the Jet has 120mm of plush Continuously Varying Arc (CVA) travel on tap that possesses the ability to tame rough trails at speed with better control and has the ability to be run as a 29er or in 27. 5+ guise. And since this frameset is poised to go just as quickly downhill as it does uphill, its geometry is dialed for all-day epics with plenty of ups and downs with a slack headtube, steep seattube, and long reach. This frame is ready for you to build it up with that trusty kit off of your current ride or become the foundation of your dream build from the ground up. It took a few years for boost spacing to establish itself as the industry standard but thankfully it allows frame builders like Niner to update its geometry to what we spoke to above. Gone are 21mm off of the new frame's chainstays helping to move the rear wheel underneath the rider for better traction and responsiveness. So even though this new Jet is more capable and has more travel than the old one, it hasn't lost its nimbleness. For fork lengths, Niner recommends paring a 130mm for 29-inch wheels and a 140mm variety with 27. 5+ and despite the newer, slacker front end, the seat tube angle remains similar to the older Jet 9 despite its shorter travel fork and steeper head tube angle. That steeper seattube is responsible for keeping you on top of the pedals for more efficient pedaling, more intuitive handling, and helps keep the front end from wandering on steep uphill switchbacks. With the recommended fork lengths for 29 and 27. 5+ wheels mentioned above, the respective headtube angles sit at either 67. 5 or 67 degrees. While riding, that angle is a pretty good balance between a quick and agile trail ...
