Great wheelset. Comes set up for tubeless, all you have to do is add the sealant and pump it up. The tires showed up already seated. The wheelset weighed 1560 g on my scales which of course is higher than claimed weight. Mavic's UST system really is nice. No rim tape needed as there aren't any spoke holes in the rimbed. A couple rides in and I can say that I am very happy with my purchase. Supplied Yksion Pro tires are good. Not amazing but really good enough for what I'm doing with them at this point in the season. Keeping in mind I did get these on sale and I might find different options if your considering these at full retail.
