We don't usually do this, but the overview of the Bontrager XXX Lite 29er wheelset as written on their official website is so spot on and concise that we're going to simply cut and paste it below. We will however add that the wheels weigh just 694 and 818 grams, and that they look even nicer in person. Honestly, we don't think we've seen a nicer looking wheelset ever. For goodness sake, they have carbon rims, red nipples, and white spokes. Nuf said. Oh, except to say that they cost $2800 for the pair. Hey, they're the best.
The official word: Bontrager's lightest, high-performance cross country wheelset, the Tubeless Ready XXX Disc features exceptionally strong, extremely lightweight High Compression Molded carbon rims mated to smooth-rolling, high-quality sealed-bearing hubs. Compatible with both Center Lock and 6-bolt rotors (with adapter--not included), the tool-free, Bontrager-engineered hubset features a 3-pawl ratchet freehub that improves stiffness, reduces torsion, and simplifies maintenance. Tubeless rims strips and valve cores included; just add Super Juice and Tubeless Ready tires.
