Mechanic's note
This bike is brand-new. There are no scratches and the components are all in perfect condition. Modern mountain bike geometry has evolved beyond traditional S/M/L sizing, with minimal differences in stack height and seat tube length. A larger frame provides a planted, stable ride feel, while a smaller frame leads to a more reactive, playful experience. Riders can now choose size based on preferred ride style rather than just height. Our recommendations reflect this modern, more flexible approach to sizing.
Additional notes
Note that dropper posts usually have a slight side-to-side play.
Certified by Upway master mechanics with a rigorous 50-point inspection for peak performance.
