Niner has dominated the big wheeled bike market since the dawn of the 29'er craze. Now, they've opened the possibilities with the new RIP 9 RDO Boost frame. This frame can accomodate either 27.5"+ or 29" wheels and tires making it possible for you to custom your bike to your particular style of brap. To them, it's not about a larger wheel size, or more accommodating geometry, it's about sharing an entirely unique experience on two wheels. Since they began in a humble Fort Collins, Co office, Niner has focused intently on building the rowdiest and most innovative big-wheeled bikes on the market. Their RIP 9 RDO series prides itself on a meticulously designed carbon fiber frame. In the process of designing this frame, Niner has revolutionized the way a long-travel, large-wheeled bike performs. The CVA rear suspension is remarkably versatile, counteracting squat and bob to absorb shock without stealing from your pedal stroke. With short chainstays and a low bottom bracket, this bike is remarkably fun.
The RIP 9 RDO is designed with modern geometry built with roomy cockpits, and a slack and low demeanor. This long-legged machine not only uses big tires to eat up the trail, but can be paired with a 160mm 29er or a 170mm 27.5+ fork allowing you to take on some of the gnarliest terrain the mountains can offer. With 150mm of rear travel coming from the Fox Float Evol rear shock, this frame is ready for some seriously rowdy fun. Meanwhile, the CVA Suspension keeps pedal performance and efficiency light and tight. This is the ultimate Niner bike for big trail day adventures, or hot laps at the local bike park.
