They feature suspension to absorb impacts from rocks, roots, and drops, providing a smoother ride. Road Road bikes are designed for speed and efficiency on paved surfaces. They feature lightweight frames constructed from materials like carbon fiber or high-end aluminum. Equipped with narrow and smooth tires, road bikes minimize rolling resistance for swift longer-distance rides.
