Whether to use professional or home-based solutions to repair carbon bike frame damage is determined by the extent and area of the issue. Professional treatment is recommended for complex breaks near joints or areas of stress, but most cyclists try to repair carbon bike frame at home using resin and patch kits.An expert technician will examine internal damage by way of ultrasonic testing or X-ray imaging. Experts restore the structural integrity to factory standards. DIY repairs, however, are cheap but dangerous if one lacks tools and knowledge. Compare cost and safety before making a decision.
