While a newcomer to making frame bags, it is well within my ability. I am located in Seattle, and can teach you how to make a pattern for your bag by phone if you would like. I could scan Seattle to see if anyone is carrying this bike yet, and presumably you could as well?

I recently had a little press about the type of work I do:http://gomeansgo.org/2012/04/10/high-above/#more-7171

if you decide you are interested.
