I run stans in all my tubes here in CO for the same goathead nemesis. My experience has been that I will get about 6-8 months out of each tube before they stop sealing. At that point the little latex bits have clumped together into a space-spore looking thing and will either just tumble around in the tube, or be big enough that it's stuck in place. Even though you can still hear liquid sloshing around, the sealing bits have quit their job. When this happens, the tube is basically toast. I tried adding more sealant, but the spore was so big it was either impeding the flow or gather up the latex. When I remove tubes in this condition they look like snakes with a belly full of mouse.
For me replacing both tubes even twice a year is faster, more economical, and less hassle than dealing with the constant flats. Here's a picture of a stans monster I cut out of a tube.<http://statigr.am/viewer.php#/detail/434216101358959711_3889190>For reference, this came out of a tube run in a 700x32 cross tire. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
