That’s very cool! Alan is THE cross bike marque. It will assuredly have a high BB as that’s a feature to avoid pedal strikes on off camber sections and tight cornering. I have a more modern Alan cross bike that I really like although sadly gathering dust as I haven’t raced in a while.
A few years back Jan Heine raced his old Alan and of course, wrote about it.
