I had put off trying tubeless just due to lack of familiarity, but after one ride with three snakebite punctures in 90 minutes of riding, I finally reached my boil over point. This kit was complete and easy to use. It took me a couple of tries to get it right on the first wheel, but after that, it was very simple. And it just works in the real world. Basically, you trade a little more time in initial setup for a lot less time spent fixing flats, a tradeoff I am happy to make. I am using Clement PDX tires, and can run pressures so low that the handling suffers without burping the tire.
This conversion kit worked great! Converted a set of WTB wheels and after only a 10 mile trial ride went on a 100 mile gravel race with no issues! Wish would have done this sooner!
