Review on 🚲 Bike Bits Presta Valve Adapter: Effortless Presta to Schrader Conversion + French/UK to US + Easy Inflation with Standard Pump or Air Compressor by Junior Samson

I guess the question is why are these stupid things even needed, especially for utility mountain bikes and the like. only pain. And why do bicycle tires spontaneously lose air at all? No blisters, no holes Probably from a wrong valve but apparently only at night. Well, at least they're colorful and cheap so I can hide them on my bike and next to the compressor and find them when I need them. By the way, it is the year 2020 and bicycles have been around for 200 years. Somebody figures out how to keep the air in the tires.
