Nice!
I found a good deal on a used Niner RLT RDO a couple of years ago. It’s been great for dirt-road and mixed-surface rides. We’ve got a lot of nice dirt roads in NH and VT.
I’m running a 46/30 front and 11-34 cassette. It came with a Shimano road compact crankset(was pre GRX), and I knew I wanted lower gearing, so I decided to experiment with the Absolute Black subcompact oval ring set. I like the ovals, especially for climbing standing — for me they seem to smooth out the dead spot at the bottom of the pedal stroke.
