It doesn't look to me like that particular bead could pass the ESC connector housing.  You could pull the contacts from the housing and then unwind things -- but I wouldn't recommend doing that unless you already knew how or had some spare housings (the little latches on the housing tend to break unless you're very careful about holding them back when you pull the contacts).

I just cut the wire, remove the ring and join it with some heat shrink tubing. The wire is usually too long anyway and you normally end up winding it up.
