It looks like it’s only paint and clear coat damage, but best have your local bike shop check it out to make sure the rub is not too deep. From my limited point of view, it looks fine.
It’s unlikely that the carbon would actually rub off from the tire. A crank or chain can do serious damage, but inflated rubber is not really up to the task of taking down the CF. If it was, you’d probably be seeing some splintering or other delamination.
I had a feeling my ignorance would soon betray me yet once again.
So the set screw limiter is a TT design found on alot of tt bikes and I’m taking it because of different wheel sizes as the OP said it was his first ride with a disc wheel or just for how far the wheel sets in? I’m having trouble wrapping my head around why there is a need for set screws in other words on TT bikes.
that is a minor issue…Every TT frame with horizontal drop out need adjustement screw as depending what tire you use… 21mm, 23mm, brand, etc…they all are different size and will rub on the frame without adjustement… so it s really a simple thing to figure out when you have the frame in front of you. Will happen with any frame and it s really a none issue. Every cervelo, p2-3-4 have those little tire rub also…
