Just got a set of Stan's Flow 29er wheels. First time I've done a tubeless setup and it was pretty easy. About 3 scoops of Stan's in each tire and the beads sealed immediately with a floor pump set to low pressure/high volume for a quick shot of air. Dropped 2 pounds off the bike with these wheels and going tubeless. I think these rims make the Purgatory 2.3 look quite plump! Quite plump indeed!
