No Flats in 70,000 Miles
Been using Stan's on 10 tubeless tires from 2.25 29'ers to 28mm 700c's for years. Have been very satisfied with the ease of adding the sealant when mounting the tire and when adding additional sealant as needed. I ride tubeless year-round in Minneapolis so the tubeless set up gets a cold weather workout. In a decade of riding 7000 mi per year, I have never had a flat that the Stan's did not seal. Highly recommend Stan's sealant pump as well.
It Works - But Not Well
It works - but is fussy for road tires. I have had much better luck with other sealant brands. I would only buy again if I had no other options
Stan's is good stuff!
Tubeless tires had started leaking badly - would go flat within two days. Stan's so far has cured the problem. No air loss after a week.
Great Sealant
Great tubeless sealant. Use for training and racing and never any issues.
the bead sealed fast, i was impressed..
used approx 4oz in each tire 29er..
