I'm running the new Shimano 7801-Sl's w/ the tubeless Hutchinson Fusion Tires. I've tried adding Stan's sealant as a precautionary measure. The instructions (quantities) seem aimed towards a mountain tubeless tire, not a road tubeless tire. Regardless, I followed the instructions and put one cup (the supplied cup - maybe 2oz) into the tires. After noticing that there was a "weight" in the tires when on the repair stand, I opened up the front and noticed a bit of a glob stuck to a spot. Some of the sealant was still liquid, but some had gummed up.
Did I put too much in? Do they all do that? Also, the sealant only seemed to work at 40psi and below, and that was on a tiny hole. Is that the way they all work? I'm trying to get this dialed in now before I get out there and get a flat agian, and don't want balls of goo in my tires while riding.
Any suggestions? Thanks in advance.
okay... did I ask a dumb question, or does nobody use these liquid sealants? Repost this in another forum?
My bike's better than me!
I don't have a worthwhile answer for you, so ... forgive me ... but many thanks for your avatar.

I've run the Stan's tubeless system in mountain bike tires for a few years, it works great for that application. Stan originally said his tubeless system was only intended for up to about 40 psi (this was more a concern about the tires coming off the rims than the sealant itself I believe). So anyway, I've only used Stan's sealant up to about 45 psi, so I don't know, personally, how well the sealant would work with high pressure tubeless road tires. I do remember a BF member who posted once, he said he worked at a bike shop very close to where Stan's company is located, and he said he routinely uses the complete Stan's system even with fairly high pressure cyclocross tires (I believe he said around 100 psi). You might go to Stan's website and email them any questions you have, they're very helpful from my experience-
