I KNOW THEIR IS SOMETHING ON THESE, but I couldn't find it. But anyway if you remove an old a head tube and replace it with a pro model headtube can you put on the current SR forks?
And i'm not gonna do more posts with "yes" words in it for the same question.
IF you ride an OLD-A model and you want to ride current SR v2 forks (threaded or threadless, doesn't matter), then you have to change your OLD-A headtube to a PRO, an OLD-B or a NEW-A headtube, because they fit SR forks.
