Review on 🚴 AerGun X-1000 Bike Pump – Innovative AerTight Pump Head for Effortless use with Presta and Schrader Bicycle Pump Valves – Built-in Pressure Gauge – up to 160 PSI by Edward Mcnamara

present Works very well for both types of valves, which is different from all other pumps I've tried. My old pump is being donated to charity and I feel a little guilty that someone has to endure this horrible thing. However. Slide it all the way into the Presta and it will accurately read tire pressure. I'm still using the pressure tool, but it's within 5psi, which should be enough. It could be closer, but the needle bounces around when pumping, and I'm not entirely sure it's very accurate (the same reading always gives the same reading). The ease of connection is the real winner here.
