OK. I think I am going to show my ignorance here but I have a question about a Hope Bulb hub I just acquired. In the place of where there should be either the 6 bolt IS mounting or the centerlock thing from Shimano there is a silver threaded ring that screws on to the hub itself. What the f is it and why cant I find any info on it!?!?!
