My LBS said they could set me up with tubeless for about $50 (cost of materials). The benefit of tubeless is lighter weight and you can run your tires at a lower pressure--no worries of a pinched flat. And if you do happen to flat, you can throw a tube in there.

My Trek Fuel had tubeless rims but the tires were not set up for it. It was a pain in the katoosh to change the tire--because of the rims. It took 3 guys in the shop 45 minutes to change the tire.

The Trek Superfly has the tubeless ready wheelset, might as well go tubeless!

My biggest concern at this point is finding the right tire for my kind of riding.
