Review on 🚲 JACO Bike Presta Valve Tire Air Chuck - 1/4'' NPT (2 Pack): Optimized for Enhanced Performance by Derrick Lowell

Just went tubeless on my mountain bike. I needed a Presta valve fitting for my supercharger to get the tire bead in place. I found these Presta valve fittings to be very limited. I ended up having to remove this product from the compressor hose and simply slide the hose over the open valve to puncture the tire bead. I then reinstalled this product and inflated the tires. Summary: They work fairly well for inflating tires with Presta valves, but you will find that this product has very restricted airflow.
