I've recently purchased a secondhand bike that's not in great condition but i'm broke. It is a monark hybrid of some kind. I notice the front wheel is out of alignment. Most bike tutorials they tell you to loosen the bolt at the top of the stem with and allen key. However, I seem to just have some sort of cap or different kind of bolt in the top of mine. I dont know how to open it? It may be something simple... any advice?
Ever seen a stem like this or know how to loosen it?

Like FBinNY said remove the rubber plug at the top and use a 6 MM hex or sometime a 5 MM . It might be frozen ,so turn the bike upside down and spray something like WD-40 into it , put the front wheel between your legs and twist the handbars until the stem breaks free.
