cite your sources. I can't find anything about the Vic Elite 2 except an outdated roadrunner sports page (which mentions fixed pins but not carbon fiber), an outdated nike.com australia page that says "product not found", and an article from a UK running news website dated August 4th that looks like nonremovable spikes but no further word.
Are you confusing the Nike victory Elite and Nike Victory 2 as the Nike Victory Elite 2? Here's a breakdown if you're confused:
2008 Olympics: Nike Victory - shorter plastic plate. Removable spikes.
2012 Olympics: Nike Victory Elite - 3/4 length carbon fiber plate. Shortly after: Nike Victory 2 - 3/4 length plastic plate, therefore a bit cheaper. All with removable spikes.
2016 Olympics: Nike Victory 3 - NEW honeycomb 3/4 length plastic plate. Removable spikes. Only matumbo 3 and mamba 3 have non removable spikes now.
