AndyMwrote a review of Stan's NoTubes Standard Tubeless System on August 21, 2014
Familiarity: I've used it several times
This is a great kit to get you switched over to tubeless like most people are running these days. The benefits were noticeable to me the first ride after dropping down to 30psi from 35... it smoothed out my ride over rocks and roots, and improved traction in turns.
Installation was really painless... I omitted drilling out my rims, since the rim strips seemed to fit pretty flush already. I did supplement this kit with the Stan's Injector, which saves the hassle of trying to pour the fluid into your tire, then not spilling while you reseat the tire. A high volume floor pump was adequate for getting a bead for me.
As the other reviewer mentioned, I also have had a harder time with a Kenda tire. My front tire is some Specialized S-Works that holds steady pressure, but the rear is a Kenda Small Block, which bleeds off about 10 psi over the course of a week. Kenda apparently doesn't support tubeless fluids, so perhaps there is some sort of issue with their rubber & the fluid.
