  1. So after the ride with the "LONG" chain, I noticed the chain was rubbing against the protective foam material on my frame. And it lightly scratched the carbon.
  2. Rode the next day with the "SHORT" chain. I put some electrical tape on in that area before the ride. After the ride I saw the electrical tape was split.
Maybe the 28T oval ring (Absolute Black) is too small for my frame. When the rotation is on the smaller section of chainring the chain seems to get too close to the frame. Is there anything I can do about it?

Here's a picture:
Glad it is looking better, I would reach out to the frame manufacturer and see what they suggest about the chain rubbing the frame and what their minimum chainring size is?
