Niner AIR 9 RDO Frame Only
$1,999.00
For a snappy whip that caters to podium-driven racers and personal record chasers alike, the AIR 9 RDO delivers lightweight responsiveness you'll appreciate on sustained, leg-busting efforts. Refined tubing shapes and modern geometry tweaks lend the AIR 9 RDO a smooth ride with powerful acceleration capability, while Boost hub spacing keeps the chainstays short, allowing for stronger wheels that give you impressive tracking at speed over rough terrain. The frame includes headset, Maxle, derailleur hanger, and seat collar.
Niner JET 9 RDO Frame
$3,000.00
The JET lands right in the sweet spot for the all-in-one trail bike. The 120mm of roll-and-go rear suspension is nicely balanced with 29-inch wheels and a 130mm fork, and the resulting 67.5-degree head angle is ideal for all-day riding and tackling any tough spots along the way. The CVA-powered magic carpet ride suspension sends you floating up technical climbs with tons of traction and flying smoothly over everything else, and thanks to Boost rear spacing you can add to the fun with a swap to 27.5 wheels and tires up to 3-inches wide.
Niner RIP 9 RDO Frame Only Push Edition
$4,100.00
Take your all-mountain dreams to the next level with Niner's king of the trail. The RIP 9 RDO Push Edition frameset features a ride-enhancing Push Industries Eleven Six rear shock for unmatched tunability and big-hit performance. Boost hub spacing sets your stance wide for increased stability in the rough stuff and plays nice with varying wheel sizes so you can take advantage of mid-fat traction with 27.5+ wheels and tires, or faster laps with a 29-inch wheelset. Niner's CVA design delivers 150mm of just-send-it suspension to give you a new lease on any trail, and with details like the 73mm threaded bottom bracket shell, internal shifter routing, and ISCG 05 tabs, it's clear Niner succeeded in building a winner.
Niner RKT 9 RDO Frame Only
$3,000.00
Hammer away at your best times with the featherweight and efficient RKT 9 RDO. This carbon full-suspension race rig floats on 90mm of rear CVA suspension that's optimized to provide a responsive pedaling platform no matter what gear you're in, and pairs best with 120mm travel forks for rocketing across any course. Boost rear hub spacing provides clearance for up to 2.6-inch tires, and internal cable routing with Di2 compatibility keeps it looking clean. Fox Float DPS Factory shock, seat collar, headset, and rear Maxle included.
Niner SIR 9 Frame Only
$1,200.00
Take charge of your ride with this Reynolds 853 steel frame designed around Niner's [R]evolution trail geometry. Ride it hard. Ride it fast. After all, it's made from a truly time-tested material that's been air hardened and heat treated. The efficient, yet compliant ride quality of the SIR 9 hearkens back to a simpler time. A time without linkages and complicated shock settings. A time where all the energy you put into the pedals moves you forward. The PF30 bottom bracket allows you to run a standard press fit bottom bracket or, if simplicity is your thing, throw in an eccentric bottom bracket and run singlespeed. A hidden plate inside the chainstay yoke stiffens and strengthens in order to improve power transfer, and 18 mounting points allow you to pack it full of the things you need for a long weekend of mountain bike adventure.
Giant Reign Advanced Frameset
$2,625.00
The fastest, most confident Reign ever built. This enduro crusher features a lightweight composite frame that’s engineered for speed on rowdy terrain. Tested by Giant pros on extreme Enduro World Series terrain, it’s ready to rip. Updated and refined for the Giant Factory Off-Road enduro squad last year, the latest Reign Advanced features a longer, lower cockpit for fast, aggressive trail riding performance. It’s engineered with a lightweight, super-stiff Advanced-grade composite mainframe and ALUXX SL aluminum rear swingarm. The Maestro suspension system delivers 160mm of smooth, active travel with a trunnion mount shock and our Advanced Forged Composite upper rocker arm—which is lighter and stronger than the previous aluminum design. And it’s all designed around the performance benefits offered by 27.5 wheels, giving you the confidence and control to be fast and loose on hard-hammering terrain.
Giant Trance Advanced Pro 29 Frameset
$2,940.00
Amp up your trail riding adventures with this all-new, all-conquering 29er. Whether you’re gunning for faster enduro times or bagging a big backcountry loop, do it like a boss on this big-wheeled singletrack shredder. It took years for our team of engineers, product designers and pro riders to create a new mid-travel 29er that met their high standards, but the wait was worth it. The rebirth of this trail bike marks a huge step forward, offering a true advantage in all-round trail performance. It starts with a full composite frame that’s fitted with our most up-to-date Maestro suspension. The Advanced Forged composite rocker arm and trunnion-mount shock help produce 115mm of smooth rear-wheel travel that’s active and sensitive to small bumps, giving you killer traction and confident control. And the frame geometry is all new, with progressive headtube and seattube angles, shorter chainstays and a longer toptube—all engineered to balance the speed and control of its 29-inch wheels with the quickness and agility you need to rail corners, hammer through rock gardens and do it all with confidence and control.
