Niner is short for 29er, where Niner began; the first offering was a Scandium aluminum 29” single-speed MTB built for having fun on the trails of Los Angeles. Currently located in Fort Collins, Colorado, their mission remains #committedtodirt. 

Niner's line has expanded considerably, but the goal is the same, more people out riding and having more fun. Their rear suspension is a patented design Niner came up with to maximize the benefits of 29” wheels without the pitfalls. Niner calls their suspension platform (CVA) Constantly Varying Arc. CVA features pivots below the bottom bracket to keep the stays and wheelbase short and separate the suspension from the drivetrain.

It’s impossible not to notice that many of their models are bequeathed the RDO moniker, short for Race Day Optimized. This means the frame is maximized to be stiff, light, and strong, all qualities a racing bike requires. While Niner does not expect everyone to race their bikes, they figure people like riding hard and getting the most out of their bikes. Niner likes to point to their SIR 9 (Steal Is Real) XC bike as one that deserves far more attention than it gets. The Reynolds 853 metal tubes bring exceptional ride quality to a proven geometry.
