It seems like most newer dirt bike and pit bike forks have larger outer diameters than 30mm. Yeah, inverted forks would definitely not work with my set up. I'm really looking for something like this:
I just need it to work with a 12mm axel, and have 30mm OD top tubes, I could use a pipe cutter to trim if they were too long (i.e. longer than 24").
Welding is pretty much not an option, I'm building this bike in my tiny 5th floor apartment in brooklyn. I don't have any welding leads/buddies either.
