I am moving away from my hardtail 29er and purchased a 650B SC. I have never had a bike with tubeless wheels, and these are already setup. My question is what do I do? I am uncertain how long they have been this way, what is in them, is it still liquid? I really don't want to go and break them down as I want to ride, but can I just add some new liquid to really "know" I have some protective fluids in the wheels?


I am reading up on as much information I can find on dealing with tubeless, mine appear to be the easier system. (tubeless ready rim and tire)


Can I just purchase some of this Vittoria Pit stop and add a small amount as needed? Are all of these fluids basically the same, what about slime, is that solely for tubes?


I just don't want to add something and inside my tires end up being a caked gooey mess.
