This is my one year experience with Mavic Kysirium USTs. Easy to set up...easy to pump up...lighter, faster and smoother. I have to do nothing with them but keep air topped up and ride. This video convinced me to give them a try. I was very skeptical so I just bought a rear wheel. They come with tires. I was so impressed that they now sit on my Guru steel and my CAAD 12. Never going back to clinchers.
