I am taking my Tarmac SL4 to the dealer on Tuesday but in the meantime wanted to get some opinions. Does this look like paint cracks or Frame cracks? You can see one in the silver one in the black.

My instinct says paint as the frame has never been dropped or wrecked.

All I see are scuffs and paint scratches.

Looks like paint but you have a 1 year paint warranty. How old is it?

This shows it better. It is 4 months old.

Well within your paint warranty.

So it looks like paint and not carbon? Would be an odd place for paint to crack.

Not really. Seat tube, right by the bottle cage inserts?

Yes. Seat tube near bottle cage. About 90 degrees from it to be exact. In a paint warranty situation would they replace the frame or repaint it?

...without an actual X-ray, unfortunately it is impossible to know. If you are original owner then you should demand a new frame. EM3

Either too brittle paint or a damaged tube, probably it´s beginning from bottle cage inserts, they are usually drilled and riveted after manufacturing, there you have stress risers.

I´ve repaired frames with cracks that begins on one point and continued all the way around the tube, regardless of layup made.

Please let the shop check it or stop riding it, it´s not worth it.
