Chips in carbon frame - how worried should I be? I am looking for a second hand road bike. This is to be my first mid-range bike, and my first introduction to carbon frames. I have done a bit of research, and am aware of the potential risks of damaged carbon frames.
However, knowing about the risks and knowing how to spot a more than superficially damaged frame are two different things.
Here are three pictures of the visible damage: scratches on the front wheel, and chips in the paint. Based on these pictures, how much of a hazard would you judge this to be?
These appear to be paint chips in areas of the bike where rock strikes are common.  I don't see any evidence of delamination--a separation of the carbon fiber weave and thus carbon fiber damage. However, no amount of photo inspection can replace a hands on one.  Were I to purchase a carbon fiber second hand, I would have a second opinion of the carbon fiber integrity done by my local bike shop or equivalent expert.
Paint chips can be covered with a similar colored nail polish or other suitable paint. There are many companies in the U.S. that offer carbon fiber frame repair if it is determined the actual carbon fiber is damaged and you already own the bike.
