I looked into buying their cantilever cross frame and couldn't ever figure out how. Never listed on their outlet page. No response to email/contact form or FB. Their USA dealer is Dean custom bikes, which also didn't respond to email, and that makes sense as there doesn't appear to be any Alan info on their site.
Oddly enough Alan does seem to do consistent business with Japanese bike shops but the runaround to get one in that manner was too much.
