I have just got a set of these from a friend that no longer wanted them after buying them.

Have just taken one of my wheels off and knocked the existing cap through like said on a previous thread, but these do not fit into the hole that is left. They are too small, nor can I disassemble the existing ones in anyway.

So my question, are these for the Irmscher alloys only (Signa etc.), and not the VX ones that are supplied on an SRi (The 11 spoke wheels)
