Bike Carbon
What are vulnerable spots on a carbon frame bike?
What are vulnerable spots to pay attention to on a carbon frame bike for inspecting small cracks?
Road bike specifically.
When I design a CF frame there are specific areas I check after testing:
1. At the seat tube expansion slot... where the seatpost goes in. This area is almost always reinforced by an aluminum sleeve but it tends to crack anyway;
2. Directly below the top tube on the seat tube;
3. Downtube at head tube;
4. Downtube at bottom bracket;
5. Chainstay reinforcement, just behind the bottom bracket;
6. Head tube at top and bottom.
The best way to do this inspection is to spray the areas lightly with water, wipe it off, then look for defects with a magnifying glass in strong light.
