Re:
There is a thread on here somewhere that discusses the relative weights of the SB & DB Bologna Lite forks.
I also seem to remember that they will have either SB or DB stamped onto the steerer, but it could be a false memory?
I've got a single butted fork tucked away, so I'l have to dig it out & check.
I have a double butted version on my '93 Zaskar and it rides really nicely with it.
