Familiarity: I've put it through the wringer
Can't say enough good things about the new Jet 9 RDO. I built mine up from the frame, basically a 5-star build but with Reynolds carbon wheels rather than Stans, and a RS Pike 120 fork (thanks for the recommendation Jason Sagar!) instead of the RS1. From Day one it just felt perfect. Super light (23.5 pounds in amedium, even with the burlier Pike), climbs like a madre, ripping fast downhill on flowy or technical. Niner definitely has the geometry dialed. Love their 5 year warranty for a full carbon bike. XX1 is a dream compared to double or triple rings. I was on the fence whether to go 27.5 or 29 (at 5'10") but I'm more about fast XC riding than techy downhills (not that the Jet 9 balks at any trail obstacle) so this bike was the right call.
