The 2016 Niner RKT 9 RDO XTR Di2 does one thing very well—fly. They pulled out all the stops to create the most efficient full suspension cross-country bike possible. The lightweight RDO-compacted carbon frame employs Niner’s patented Constantly Varying Arc (CVA) rear linkage, which allows pedaling forces and suspension travel to operate independent of one another, so you reap the rewards of every watt you put into the pedals while still enjoying the benefits of a fully suspended race rig.
