The sealant that has saved every single super cold fat bike race from disaster. This is MADE for fat bikes right outside Austin, formulated to work in extreme frigid temperatures, saving us when our race starts hit -30F. Absolutely necessary for winter riding, just buy it now. Yes, this can mix with your other Orange Seal products, but I recommend going whole hog and do a proper swap if you're racing in the negative temps.
Orange Seal is all we use, but make sure to check out the chart in the pictures to see which sealant works best for you.
