I just mounted up a Mythos tire to the new Stan's Olympic 29er rim. I used the rim strip. Wow! I am impressed how tight it fits. I mounted it up (took tire lever to get it on) and it fits really tight. I followed Stan's recommendation to air it up before putting in the latex goo. It aired up quickly with just the floor pump and held air well. It was really hard to get the bead off the rim again, it took a wet tire lever to do it. I then added the stuff and did all the tricks the website video's said to do. Aired up in less time than a tube would. The tight fit really lends to confidence. I am trying this on the back first so far due to a ripped liner. After having the Dyad rims (with the loose fitting tires and having tubes blow out the sides because of the loose fit) I am happy with how well the tire fits on this rim. I will be trying these out on the trail soon.
