Without the International Mountain Bicycling Association, exploring trails and honing two-wheel skills would involve shotgun-wielding landowners and ticket-issuing Rangers. Thankfully, IMBA"s existence encourages teamwork among diverse trail-user groups, preserving and expanding access for off-road cyclists. And what better way to enjoy those trails then on a Limited Edition Niner R. I. P. 9 RDO / IMBA SRAM XX1 Complete Mountain Bike?

P 9 RDO is a revolutionary monocoque frame. Using the latest computer modeling to explore every conceivable option, the RDO"s structure has a massive bottom bracket area with a direct-mount front-derailleur interface, 142mm rear spacing, titanium frame guards, and carbon linkages to boot. But, those attributes are worthless without a proven geometry, and luckily, Niner"s already sorted its mid-travel geometry with the alloy RIP 9. And while the RDO"s angles are based on its alloy stable mate, it is, for lack of a better term, no carbon copy. The RDO treatment includes a redesigned rear triangle and suspension links, ...
