Hello, on my 2020 trek checkpoint, there are two plastic covers on the top tube. When I removed one of them underneath is just raw exposed carbon As you can see in the photos. There are no screw holes. The bontrager adventure bag comes with screws see link below. Any insight on how to install it? Are there special screw holes that need to be installed in there as a separate piece part that needs to be bought? Or should I use these plastic pieces that were there initially? Thank you

  1. that’s carbon? Man…that frame looks compriomised. That scratch crack goes all the way around.

    I think the threads are just really dirty, you’ll want some M5x12(ish) button heads, most hardware stores should have some for pretty cheap.
