Hey Matthew, Smaller wire is fine. The wire that Velo Lumino sells is perfect. Any 22 or 24gauge multistrand wire would work but the Velo Lumino wire is flexible and has very durable insulation. You could also seperate the BM dual strand wire. The insulation is thicker and less durable but works fine.
If the hole diameter is too small to pull two wires you can ground through the frame. Ground one side of the dynamo to the fork eyelet https://photos.app.goo.gl/xBqTJ575zxQkeUC49 then ground one side of the light to the mount or other hard point https://photos.app.goo.gl/wPGMviZF9n5cYycn6. Run a single wire through the fork and connect to the light. Hope that makes sense! I can draw up a diagram if thats helpful. How much wire do you need? I might have some to spare if needed. Also what light and dynamo are you using?
