I am particular about setting the stops on the F Derailler so it cannot happen- it still does occasionally. So to protect the frame- I have put some clear plastic- like thick sellotape- around the area to be damaged.
Yes, that's the one. I am building up a carbon fiber frame and have seen what a dropped chain can do to CF. I'm thinking about using a chain guide or wrapping part of the frame around the BB in handlegrip tape. Suppose I could do a web search but what is sellotape?
