Sort of a short update here since I've got something of a magnum opus brewing in the background.
Testing of the new FSW 23 (pictured here) continues. Used in a mountain bike setup, the FSW 23 rims are working brilliantly set up tubeless. One layer of Stan's Yellow Tape, a 29er rim strip, and a scoop and a half of Stan's sealant. At 27psi, the Geax tire feels incredible and DOES NOT BURP. I've got more confidence in this setup than I've ever had in a mountain bike wheel.
A little hint for the folks at home - the pressure gauge on your pump is probably lying its ass off to you. Of the four pumps I've tried, none even came close. All were high, by around 5 to 8 psi in the CX/MTB pressure ranges. The Topeak digital pressure gauge is a bit fidgety to work with but I think it or something really similar is absolutely mandatory if you want to really know where your pressure is.
Next week I'll be out on an actual CX bike with actual CX tires and will be putting the tubeless setup to the test in its real configuration. Pretty confident that this is going to work out great.
