Truly all-mountain.

29ers are built for speed. That's a simple enough fact. It also stands to reason that a little bit of suspension will facilitate that hunger for speed, but too much will bog you down. Given that Niner bills the R.I.P. 9 RDO Carbon Mountain Bike Frame as the flagship chassis of its 29er-only fleet, it's not surprising that it combines 5in of enduro-grade travel with the XC tendencies of 29-inch wheels for a machine that's truly all-mountain.


The Constantly Varying Arc (CVA) suspension platform at the R.I.P. 9's heart is the key to Niner's fame. That's because the CVA suspension's lower link sits below the bottom bracket, which puts bike's virtual instant center ahead of the drivetrain and effectively isolates the drivetrain from the rear triangle. Pedal input isn't lost to compression in the suspension, and you won't suffer kickback from chainstay growth while taking advantage of the 29er's ability to push through trail furniture.


No amount of big-wheel speed or enduro-minded travel can save a shoddy frame, though, so Niner dumped every bit of its R&D nous into the material lay-up of the frame's two triangles. The frame began life as a gleam in a pixel's eye in computer modelling software before moving through exhaustive phases of virtual and then physical prototyping. The final product replicates the virtual models' precise standards with Niner's internal compaction system, which uses internal bladders for virtually perfect tube shaping with no imperfections or resin pooling. This let Niner dial the lay-up, adding stiffness through the drivetrain spine and keeping the frame light and compliant where those qualities benefit the ride most.


Compared to its alloy counterpart, the R.I.P. 9 RDO's carbon build also allows for an extra 10mm of travel while shortening the chainstay by 5mm. This combines with the moderate head tube angle for a fast climbing, sharply responsive, nimble bike that still tracks through terrain with all of the confident aggression you'd expect from the Race Day Optimized initialism in its title. The frame is finished with carbon links for a suspension system that just says no to lateral flex under input load, shuttling your power straight to the rear axle.
