I’ve been using Stan’s sealant on my tubeless tires for years! I have been having issues with a new tire for a while. It was like the bead wouldn’t seal on a specific spot and my tire was constantly leaking air. The local bike shop couldn’t fix it. I bought this product because it claimed to help seal bead leaks. So far so good! I really didn’t want all the doo-dads for the schrader valves. It took me a minute to figure out how to get the presta valve stem out but once I did- it was super easy to install the injector thing and add the sealant. After inflating my tires- I went for a 20 minute bike ride to get the sealant all around my tires. I’m going to take this bike out to pima-dynamite trailhead next weekend in Scottsdale AZ to see if the sealant holds up!!

Works like a charm!

Size: 8oz MTB Tire Sealant Kit

I’ve used TireJect before. I used it on my golf scooter to eliminate a slow leak. They only hold 14 psi, but over 4 weeks it was down to 10. The TireJect fixed that immediately. Very easy to use.

This stuff is amazing

Size: 8oz MTB Tire Sealant Kit

I have tried several tire sealants available for my tubeless mountain bike tires. TireJect far out performed all of them. The sealant is holding up well and definitely seals up punctures quicker. I've been stranded miles from the trailhead before and never again with TireJect. Carrying your bike back to the car is a walk of shame nobody wants face. I also liked the included injector better than the others I've had and like that's it's part of a complete kit.
