Description
The Niner JET 9 RDO has now fully evolved from a cross country machine to a true fast trail bike with shorter chainstays and slacker head tube angles. With a Boost 148mm frame standard, 120mm of rear wheel Niner CVA travel, ISCG 05 tabs, new [R]Evolution geometry that handles both 29" and 27.5" Plus wheels and tires, as well as the full-on RDO carbon treatment, the Jet 9 RDO is ready to tackle aggressive XC/trail and more depending on your optimal configuration. Climbing, technical capability, nimble handling and control; with 29ers it used to be, as the saying goes, pick two. Now you don't have to.
Boost spacing for the rear triangle has been a game changer for many designs, and for the JET 9 RDO the opportunity to add tire clearance (29" to 2.5", 27.5+ to 3"), shorten the chainstays (to 434mm) and add frame stiffness from the 12/148mm rear dropout and new bottom bracket junction. Combined with the bump from 100mm to 120mm of rear wheel travel, the overall combination delivers a much more capable design. By changing the front end to accommodate a longer front center position with a shorter stem and wider handlebar, and moving to a 29er geometry optimized for a 130mm fork delivered a 67.5° headtube angle (140mm 67° with 27.5+). Now the design is much more capable on technical descents, with back-end flickability and front-end quickness pure trail riders absolutely require. No more compromises for the JET nameplate.
The RDO-level carbon frames from Niner are also no compromise. The premium quality carbon materials and advanced Niner CCS process uses rigid internal molds, which increases the level of compaction and precision in wall thickness. This reduces resin build-up from the compaction process and the end result is a frame that is internally clean and clear of excess material, and much greater control over the construction itself. The light, stiff frame features the 12/148mm Boost rear drop out, with a replaceable derailleur hanger and increased lateral stiffness from the bottom bracket to the rear axle, resulting in better power transfer. The wider bottom bracket junction and the tapered headtube also benefit greatly from CCS, creating a frame that exhibits much improved torsional stiffness. ... Read More
