Orange Seal - Subzero Formula Tubeless Bike Tire Sealant | Effective Down to -20 Fahrenheit | for Fat Bike, MTB, Road, CX and Gravel Bicycle Tires | 16oz Refill

Our local bike shop ran out and we ended up needing to get some before our next outing on the MTBs. Quick delivery of a known good product.We've even used this to extent the life of basketballs, footballs, etc. anything that has a small-to-medium leak gets a much longer life now = good stuff helping us to avoid landfill.

Poduct is great, amazon is terrible

I prefer Orange over other brands. Has always worked well on my Road and MTBs. I tend to use about 1oz over recommended amount as I run 32 road and 2.3 / 2.5 mtb

Last ride out rode over what turned out to be a thorn bush. Picked up a 1/8 th inch thorn in the tire with the brush. Snapped off the brush and finished the ride with the thorn. Pulled out the thorn when I got home and rotated tire and leak sealed right up. Been sitting for a few days and still holding air.
