I will test both of these wheels on the Fantom and comment on how the Vuelta wheels compare to the XTR. I can say at this point with 82 miles now on the bike, the Vuelta wheels are GOOD wheels.
1 Pound/16 Ounces= 454 grams
1/2 Pound/8 Ounces= 227 Grams
Here is the XTR wheelset along with the weights of the parts going on.
I bought the wheels set at the end of last year on eBay when Microsoft was running their cash back program and got the wheels for $570. Great deal for a $1200 wheelset!
XTR 12-34 Cassette $235. eBay $140
XTR Rotor. Retail $140 for the pair. Bought new on eBay new for $75.00 including shipping. Yea, I know, a great deal.
I chose these Michelin XCR AT UST tires/tyes because they are tubeless, great tires, and are normally $60 per tire or $21 on eBay. I wanted to get some sweet Continental race tires but they are more expensive but much lighter than 757 grams.
Here is the final wheel weight including Stans in each wheel. 8 pounds 9 ounces
Here is the Vuelta Team SL Disc wheelset with all the parts.

Final wheelset built up. 9 ounces lighter. Keep in mind though that this has the XT cassette on it which is heavier than the XTR but the tire and tube combo is lighter than the Michelin UST tire that I chose to put on the XTR wheelset.
I think we forget how heavy tubes can be
I have ridden Hutchinson Python tires for a long time because they are light and have tall side walls offering a big tire for a 2.0
