These frames are super duper lightweight, strong, and offer top-notch performance in terms of stiffness.

If you've ascertained that what you are dealing with is a small crack or surface damage, here are the steps to repairing your damaged carbon bike frame:

  1. Clean the damaged area. Use a degreaser or rubbing alcohol to clean the area around the damage. This will help the repair bond better (trust us, you won't want to skip this step for sure).

  2. Apply epoxy. Use a brush to apply a small amount of epoxy to the damaged area. Make sure the epoxy covers the entire area.

  3. Insert reinforcement. Reinforce the damaged area by inserting a piece of carbon fiber. The carbon fiber should be slightly longer than the damaged area. This ensures better adhesion and a long lasting repair job.

  4. Apply more epoxy. Apply more epoxy to the area, making sure to cover the carbon fiber COMPLETELY.

  5. Let the epoxy cure. Let the epoxy cure for 24-48 hours, depending on the manufacturer's instructions. Be sure to follow the instructions provided by the manufacturer as the curing time for different brands can vary quite a abit.

  6. Sand the area. Use sandpaper to smooth out the repaired area. Remember those extra long strands? Here's where you get the extra bits off.

  7. Paint the area. Paint the repaired area to match the rest of the frame. For a guide on how to paint your bike, check out our article on How to Give Your Bicycle a Custom Paint Job.
