Can't find them anywhere. There's so much niche stuff produced in China, it's almost unbelievable that nobody seems to do them.
I know the small clamp size on a drop bar would likely prove prone to failure, but surely they could use thicker tubing? I know that then makes it heavier, but it still has better ride quality than ALU.
Maybe my Google-fu is just lacking? Anybody know of or can find a source?
