FondTF2 Posted March 18, 2021 Share Hi Hubbers Even though I am going to get a stress test done by Carbon Bike Repairs, thought I would get hublands opinion first on whether this is indeed a crack or maybe just a paint rupture. Area of concern circled in red. BTW this is where the FD mounts. Link to comment Share on other sites More sharing options...
AdamA Posted March 18, 2021 Share Without being able to get touchy-feely with you bike I can't be certain.... but that looks cracked! Link to comment Share on other sites More sharing options...
Mars1967 Posted March 18, 2021 Share I certainly hope I am wrong but it does appear to be cracked. Link to comment Share on other sites More sharing options...
Chris_ Posted March 18, 2021 Share It looks like the diameter of the tube changes? if artificially so thats a crack vote for squeezed to death. If thats just how the frame shape goes - 1 vote paint. Link to comment Share on other sites More sharing options...
TheoG Posted March 18, 2021 Share The focus on your photo is out so difficult to see but my guess is its a crack. Best to ask the carbon specialists though. FondTF2 1 Link to comment Share on other sites More sharing options...

SwtCraigMachine Posted March 18, 2021 Share If you tap a coin (or similar) down the length of the seat-tube, the sound will likely change as you get closer to the 'crack'. If the sound doesn't change, there may be more hope of it being paint/superficial deformation. It's by no means a foolproof test, but it might provide another reference point! Good luck, regardless.

Grant G Posted March 18, 2021 Share I think you need to go on diet or stop gym sessions using a wrench!! Onky kidding, best you get it checked out by the pros. looks like damage to me though. Link to comment Share on other sites More sharing options...

Robbie Stewart Posted March 18, 2021 Share That tube looks fooked. I dunno if I would risk sitting my big ass on that post. It will likely fail at the worst possible moment. ChrisF 1 Link to comment Share on other sites More sharing options...
Martin PJ Posted March 18, 2021 Share It's cracked, fixable. There is a guy in Durban, very good and fast, if you want his details PM me. I have used him for road bike. Link to comment Share on other sites More sharing options...
love2fly Posted March 18, 2021 Share It looks (by the surrounding blkack smudge) like it took a hit? I wouldn't give CBR the time of day, find someone more reasonable. Link to comment Share on other sites More sharing options...
SwissVan Posted March 18, 2021 Share Hi Hubbers Even though I am going to get a stress test done by Carbon Bike Repairs, thought I would get hublands opinion first on whether this is indeed a crack or maybe just a paint rupture. Area of concern circled in red. BTW this is where the FD mounts.The paint is already kaput, remove the paint so you can see clearly what’s cooking underneath. I’d hazard a guess and say it’s only the paint that is cracked. Edited March 18, 2021 by SwissVan Rob K, FondTF2 and dasilvarsa 3 Link to comment Share on other sites More sharing options...
