Hello!

I'm on the prowl for a new bicycle frame. I ride a 50cm frame, and I wanted to have it made with a very light tubing.

I read... somewhere... (Where? I CANT FIND IT!) that a tubing manufacturer makes .6-.4-.6 tubing for the Japanese market and that it works well for a lighter, more flexible small frame. Kaisei? Ishiwata? I don't recall.

Is anyone familiar with a traditional diameter DB tubeset like this?

Thanks!
