My previous post turned up a couple of surprises about SB1995. The first, smaller surprise, was the owner’s initials on the fork. The bigger surprise was the Imperial diameter tubing. SB1995 reinforces my belief that SBDU frames can be read like a book, but like a good book, it can come back and bite you with unexpected twists.
