I am new to the forum and I have a very Perplexing (to me anyways) question/problem.
I currently ride my steel single speed with a chainring that is 42t. It came to me with this size ring and has not changed. This is in part because the dimple along the crank side of the frame is extremely small as you all can see.
Is it possible to extend the dimple further back to fit a larger ring or would it make the frame structurally unsound? I cannot go to a smaller rear cog and there is no room to move the chain line further out.
