there is no pinch bolt its just like one blot straight down the tube cant see anythin else n tried beatin them off n they wont budge
if zip forks are anything like mine where, they might be seized. Mine took a good few hits with a hammer as well as a jack between the forks and handlebars in an attempt to separate them.
it took me ages to get my zips handelbars off i didnt notice how they went on untill my dad said it was like a bycycle lol got them off in a jiffy when he told me lol what a dumb moment i had lol
