I need to know if the Chrome Carrycot Ramble also fits the Versetrax.
Your question is not completely clear to me. The Joie Ramble carrycot DOES fit the Joie Versatrax, yes. However, the Chrome model has a DIFFERENT carrycot, not the Ramble. And that Chrome carrycot doesn't fit on the Versatrax.
So be sure to check the bassinet model and/or the attachment system - the Chrome one has a long, kind of "sharper" attachment that will NOT fit the Versatrax, however the normal Ramble has a shorter, rectangular attachment system which will fit the Versatrax.
