BONTRAGER SUPER JUICE TUBELESS SEALANT Bontrager's Super Juice sealant does away with tubes. Running tubeless is lighter and allows lower tire pressures for better traction without worrying about pinch flats. Super Juice flows easily through Bontrager Tubeless valves with removable cores so you can set them up without removing your tire. It requires as little as an ounce to seal Bontrager Tubeless Ready tires and its long lasting formula works for months without drying out.
