Any question answered...

Not sure if I should be asking this here or in the mechanics thread but here it goes. I just bought this carbon wheel:

Arrived today, extremely excited with the apparent bargain I had scored. Upon close inpection, there is a kink on the edge of the rim on one side. It looks like it deviates out by about 2mm, like the rim has bent outwards. The kink from where it starts to where it ends is about 2 inches long. Its just on the one side so its nothing to do with truing.

What do you think it could be? No visible cracking or anything like that there, doesn't appear to be fragile. Could a tyre lever do this? Or a blow out? Should I be sending this back to the seller?

I was watching this wheel too. The earlier DT Swiss carbon clinchers were known to delaminate under the heat of prolonged heavy braking, which would manifest in a similar way to what you've described. Naughty seller, methinks.
I'm sure either Dammit or I (or me, Schick) would take the carbon specific pads off your hands if you wanted to offload them. Not all is lost, don't worry :)

The plot thickens. I noticed it has 4 unoriginal spokes too. They are round (instead of bladed) and the white paint is blobby, like it was some kind of rattle can jobby. What a cunt of a seller. I'm not even going to send it back, its a death trap for the next person they try to con.
