          Description
          Crafted from high-strength aerospace-grade aluminum alloy with one-piece forming technology, this bicycle frame features precision-butted tubing that delivers excellent lateral rigidity and impact resistance while keeping overall weight low. It effectively reduces overall bike weight for more direct power transfer, making climbs and long rides less strenuous.
          The frame adopts a standard BSA threaded bottom bracket design, compatible with most mainstream BB specifications on the market. It ensures easy installation, minimal power loss and crisp pedaling feedback. Full internal cable routing allows all cables to be hidden inside the tubes, giving the bike a clean, streamlined look while reducing aerodynamic drag and protecting cables from wear caused by water and grit.
          The surface is finished with a fine sandblasted anodized process for a premium metallic texture, excellent wear and corrosion resistance, and reliable performance in variable outdoor riding conditions. Compatible with road bikes, gravel bikes and touring bikes, it is a cost-effective core component for DIY bike builds and original frame upgrades.
