This is a good thread, and a very worthy project.

There is a guy who is doing some amazing machine work. He's currently doing hubs. See this review! http://wheelfanatyk.blogspot.com/201...b-is-born.html

He sent a note saying that when he's done with this run of hubs, he's moving onto cranks and would consider a prototype triplizer for 122bcd.

I'm still hunting for a 37t 122bcd ring, should anyone discover one!!!
