100% toast.
In the shop, when we get new bikes in, if the bars are already set up and taped, we back the tape off and check the bars here for indentations. If we find them, we immediately warranty the bar before assembling the bike for the shop floor or the customer. Damage like this is a non starter.
Damage here is super not that chill at all. The way these bars are constructed, the tops are molded separately from the drops, then to finish the bar, the drops are bonded into the tops. Why? Well, this way, its way cheaper for brands to make multiple sizes. They can make 38-46cm tops, and then *one* set of drops. This reduces the costs of the molds. Also, they can produce a wider variety of bars this way. Look at Whiskey bars. They have the 6, 12, and 24 degree flair. All those tops? They are the same mold, but its the drops that change. So, with like 6 different molds, they can make like 3 different bars with 3 different widths. It saves them from making 3+ more molds.
So, right at this junction you’ve pictured, there is a bond. And, that bond, is the weakest point of the bar. Its the most likely section of a carbon bar to fail. Any damage here is bad. Don’t ride bars that show this damage.
