Presta valves are common applied on high-end bikes. But they are not compatible with conventional hand pumps and gas station compressors that utilize Schrader valve connection.
When you have a leaked tire outdoor and without bringing a bike pump, the simplest way to inflate the presta valve tires is find a gas station utilizing Schrader connection compressor and install these adapters.
The package includes 5 pcs of adapters so you can carry some of them on the go and put others anywhere you want to have easy access.
