different jerseys and gear suddenly available todifferent users?

I’ve noticed there are a lot more kits on the game than are available through level promotion or special ride promotion… today i saw a level 15 rider with a sweet rear disc wheel which I’ve never had access to up to level 24… is there a different unlock kit for different riders. also i’ve noticed a lot of different jerseys on the game that are not a part of any special event or level unlocki including the world bicycle relief jersey being worn by some on game despite zwift and world bicycle relief saying it was only available for 48 hours in oct/nov. anyone have any thoughts? just curious more than anything else. 

Here is a site for some promo codes for Jerseys: http://www.titaniumgeek.com/cycling/zwift-promo-code-2/

I think the disk wheels were a limited offering: https://support.zwift.com/hc/en-us/community/posts/203328753-Missing-Disk-wheel


Cheers Paul. I’d seen this before but just seems like there are many more jerseys out there now which look to be in the site above … thanks. J
