Dropped the fork off at Porter Customs to be straightened out a bit!

I was at the LBS yesterday to try to find info on French bottom brackets and they said to use a threadless bb. One made by sunlite I believe. Has anybody had any experience with this setup?

Still need to find inexpensive 160 mm cranks and single sprocket before deciding on the bb. Probably going with an old Sugino set.

Thank you for all the help with this.
