Presta valve pumps are designed to inflate the slender, high pressure Presta valves commonly found on road bikes and many mountain bikes. To use one, you first unscrew a small captive nut at the top of the valve to open it, then attach the pump head and inflate, finally screwing the nut back down to seal the valve after removing the pump.
Shop for a bike pump from brands such as Bontrager, Lezyne, RockShox, Silca, Specialized and Topeak amoung many others.
Gravel & Road Bike Pumps
When shopping for a road bike pump, prioritise a high maximum PSI to reach the typically high pressures road tyres require, usually 80-120 PSI or more. Additionally, look for a stable base, a comfortable handle, and an accurate, easy-to-read pressure gauge to ensure efficient and precise inflation before every ride.
