I am extremly pleased with this tire. I was skeptical because I had never heard of the brand. I purchased the SE3. I've riden on it once and my friend told me that I was riding harder and faster through the corners than I ever had in the past. This tire sticks in every type of terrain. We rode through wet clay, mudd, hard pack, rocky, and sandy stuff. It didn't falter once. As for installation, it was average. No harder or easier than any other tire I've done before. But I also have a friend help, 4 hands make quick work of a tire change.
