I was riding Mavic Kysrium Elite clinchers with Vittoria Corsa tires before I switched. I was quite happy. But, then I saw a GCN video. So, I tried a rear UST. I was amazed. It felt smoother, more comfortable and seemed to roll effortlessly. Instead of 120 psi, I was running it at 95 psi. I felt like I had a new and faster bike. I know this sounds a bit crazy but that was my reaction. Here's the GCN video....
I had heard that tubeless was kind of a nightmare to inflate. Some need a compressor to inflate. But, Mavic have created a wheel/tire combo that can be inflated with your floor pump. So, I was pumped. (Pun intended) I have 3 months on them and I love them. Front and rear wheel/tire cost me a little over $400. I just checked the Competitive Cyclist site where I bought them. Best mod I've made in 40 yrs of cycling. Just my experience.
