So, I've got a 1992 Cdale that I'm trying to freshen up and make my own. I've removed the cateye reflector from the front. It was held on by acting as a washer between the headset and the locknut. Now that I've removed the reflector I've got a gap between the locknut and the headset. Seems likely that the headset will eventually work its way loose this way. What's the deal? Do I need a locknut with more threads? Am I missing something here?
