Crack in carbon frame

[Broker]

What is the best way to determine if a small crack that is visible at the junction of the top tube and seat tube is purely cosmic (just in paint) or a serious problem starting to develop. Its been visible for the last four months and about 2 mm long. Does not increase in size or show movement if pressure is applied from the side. Any ideas will help. I will post a picture tomorrow.

very loud cringe-like sounds (louder than BB) should be the first clue , take it to a expert painter (cars, bikes , boats ect..) they will be able to determine if its terminal or not

if under warranty both should be covered, take the bike to the LBS you purchased it from and send it back to distributors

Post a pic so that we can see.

 

Best advice is to take it back to your LBS. unless you bought it second hand
