Hi guys I need some technical assistance. Please view the attached pictures... I have purchased a second hand fork, if one looks at the images, the new fork is missing "the black ring" that goes on to the base of the steerer. Is this a separate part that I need to buy or can I remove it from my current fork? Also, what is called if I need to buy a new one. The previous owner had an adapter as he used it on a bike with a tapered headset.
