Bontrager's TLR Tire Sealant does away with tubes. Running tubeless is lighter and allows lower tire pressures for better traction without worrying about pinch flats. TLR Tire Sealant flows easily through Bontrager Tubeless valves (sold separately) with removable cores so you can set them up without removing your tire. Its unique formula coats the inner walls of your tire to repair punctures as soon as they occur. It requires as little as an ounce to seal tubeless tires and its long-lasting, non-corrosive, ammonia-free formula works for months and plays nicely with aluminum rims and rubber tires. Available in a 32-ounce size for your home shop or a convenient 2-ounce size that works great for topping off your sealant levels.
