I was wondering if it's some kind of modification by a previous owner. It was where the bare cable shows on the photo, the cable went inside it (via the slot) and the item slid up, threaded end first, into the twistgrip housing as per the route of the cable. But there appears to be nothing to stop it sliding down again. I don't get it. I guess the thread is redundant anyway. Could it be a spacer of some kind? What should be where the bare cable is?
Also, see other photo, isn't this the adjuster, about eight inches down from the twistgrip? If so, do I need more than just that one?
