Wanted to post this. Just gave my buddy my older pair of Stans Alpha 400 wheels. Theyhad Specialized Captain CXs on them but they were worn and he had a new pair of Maxxis Raze tires. Install was pretty easy and so we set out for ride. About 100 yards into the ride, the rear tire blew off suddenly with ensuing carnage. Tires were at40 psi when we left and the bead was evenly seated. Some sites say these are ok tires to run tubeless and some say not; obviously I think there are better choices
