Review on 🚴 TSI-1 Tubeless Bicycle Tire Sealant Injector by Park Tool: Boost Your Tubeless Ride! by Pauly Blake

Adding sealant to a tire can be a chore; Either remove a bead and fill it in, or pour it (slowly) through the wand with the core extended. The first option is more time consuming and usually messier. And after that you need to reinstall the bus. The second option is cleaner, but the stem is so small that you need to pour 1 ml, let it "breathe” and repeat. I've tried all sorts of things. I even have a piping bag attachment to use as a funnel on tour. So slow. Very tiring. And there's no easy way to be 100% sure how much goo you've poured into it. This Park Tool "injector" is a simple, direct and quick way. The presence of a "needle" in the tire solves the "breathing" problem. My only comment is that this is basic hardware. It's well made, but a cheaper option might be in order.
