The klunker is a single speed—will be. I was thinking like a 38/17 for it, within what I can usually find for bmx chainrings. For the Rincon I'll take your advice, I've never seen bigger than a 40t in general searches. I might look at fixie cranks for that one. I've seen bmx looking fixie cranks, but they all seem to be like hollowtech sets.
