Hey guys, I rode my first Stan's setup today on a demo bike. I didn't really know quite what it was when I got on it. It was inflated to a normal for me 30 psi. The rims were DT-Swiss and tires were Maxxis Minion DHFs. The tires/wheels rode fine up the climb, but could have used a bit more air since the sidewalls are thinner than a typical UST sidewall. I could occasionally feel the rim bounce off the ground. At that point I thought there were tubes in there as the Stan's valve doesn't have the telltale nut of a UST valve. What really gave it away for me was on the very first turn (for Bushwacker, this was the first spine on the top of Spear) of the downhill where it made a huge racket and the tire had the biggest burp I've ever experienced. There was a ring of dried Stan's hanging from about 150 degrees of the tires bead. This is where I feel that the ghetto solutions are a fail relative to true tubeless setups. IMHO you need to have that dedicated tubeless interface between tire and rim. On the plus side, the wheel did reseal itself at once without too much loss of air for me to continue. I kept rimming the wheels when I hit stuff, and I had to slow down for corners, but I could still ride pretty fast as long as I made sure that things were hitting the back wheel dead-on. They felt pretty bad on sidehills though even before the burp, you could feel it trying to roll. About halfway down, I caught up with some Quebecois guys and borrowed their pump (it even had a gauge) re-inflated to 35 psi and continued with no further problems. At 35 psi though, I felt that a lot of the advantage of tubeless was negated. It was bouncier for sure.
