Two days later, I'm surprised that Sixty Fiver hasn't been by to mention Arvon Cycles. I'm pretty much only familiar with Arvon's work through Sixty Fiver, who's been doing some work with him lately. So I don't know much about his experience with mixte frames, but he's been at it a long time, I'd be shocked if there's a style that he hasn't built.

If Sixty Fiver doesn't pop in soon to comment, maybe drop him a PM.
