TLR is a small bottle of sealant designed for tubeless tire systems. Going tubeless can be fun and a pain in the ass, however, it’s beauty is that you don’t have as much flat trouble typically.
But now most tubes have a removable valve core whether they’re schrader or presta. When that valve core is removed you can take a bottle of TLR, put it inside your tube and then reinstall the valve core. Be sure to shake the bottle well, you want to ensure all the sand looking stuff made it inside.
Time and time again it has worked and has saved me from changing a tube while out riding. There is no sense in not investing in this product to make your rides more enjoyable and safer.
