yes, I know I'm resurecting a 3 year old thread, but it is dealing with the tubeless question. I got a pinch flat on my ST2s today and noticed the rim tape said "tubeless ready". I'm convinced that the pinch flatwould not have happened running tubeless. The impact was mild and the rim was undamaged, but the impact was just enough to snakebite the tube. I'm going to run tubeless in my occasional ST2s called "Sunday" and perhaps more logically in my summer commuter "Utica" and see how it goes. One concern is that the bike does need to be ridden regularly or the tubeless sealant will flow to the bottom and settle. I'll report back here with findings.
