I couldn't believe he dropped that much weight off the bike, that is a ton! It's not all from the wheels though, it's a combination of everything: wheels, tires, and no more tubes.
Going tubeless he lost about half a pound.
The new tires dropped around half a pound (I think, that's assuming he had the heavy wire bead version of the 29-2 tires, which I'm not positive of)
I'm not sure how the centerlock brake rotors compared to the six bolt.
The wheels were the rest of the weight. And they weren't even that light! The rims and spokes are fairly light, but the hubs are heavy, but they're reliable and easily serviced if need be and a lot less expensive than some of the lighter options.
