Gravel frames are the core components of bicycles designed specifically for gravel riding, combining the speed of road bikes with the robustness and adaptability of mountain bikes. They can accommodate wide tires to adapt to different road surfaces. Our carbon fiber gravel frames can accommodate tires up to 700Cx47C, with bottom brackets available in BSA and T47 to meet the needs of different riders. We also have upgraded, newer gravel frames with UDH hangers.
