Niner 2021 RLT 9 3-Star 650b Gravel Bike (Forge Grey/Skye Blue) (59cm)
An excellent bike that is a blast to ride. Coming from a more traditional road bike, the frame and wheels feel substantial and sturdy, able to hit bumps and slide around in gravel with confidence, but the bike still flies on pavement when you hit the gas. I added a PNW Coast dropper post, after enjoying droppers so much on my mountain bikes, and it was a great decision.
