She bought a 47cm frameset and built it up with Ultegra 11-speed, Easton SLX wheels and Spyre brakes (closest to Niner's 4-Star build).
Loved the bike's ride and handling -- note the smiles in the pics.
However, the small frame gave her a bit of toe overlap due to the short front center distance (583mm). It was fine for 99+% of the riding, but her shoe hitting the front tire spooked her on tight turns, especially on sharp, steep switchbacks. (A not uncommon issue, and a result of not being able to arrange a test ride.) Not wanting to make the simple cure - shift cleats forward or wear smaller shoes - she moved the components over to a 46cm Crux with a 10mm longer front-center. She's a happy camper now -- sometimes small changes make big differences!
End result: a near new 47cm Niner RLT frameset is now for sale.
