huh, I just put a set of disc style on ebay... the stud extenders were stuck on the hub and by hand it felt like they would strip so I left the on the hubs lol. so rear hubs are included.. if you soak them in something it would probably be easier to remove them. I just gave up as I have a set on the front and pulled the rears to sell them. but now we're selling the whole bike so I really don't want anymore LT80 parts around lol
