| Presta valves on both my Hard Rock and Rachel. |
Over the past twenty years, Presta became the default on most new adult-sized bicycles. Because Presta valves are narrower and longer than their Schrader counterpart, the evolution began with skinny racing tires - a smaller rim hole equalled stronger wheels. The longer Presta valve can also accommodate different wheel depths. The Presta standard eventually carried over to bikes of all styles, in my opinion, because of marketing hype, not strictly for the select ridership where it made the most sense.
Presta valves are valuable for those seeking a tubeless setup, primarily for modern-day mountain and gravel bikes, and the rugged terrain where punctures are more prevalent. Tubeless requires constant monitoring, ensuring enough sealant, and often constant inflation/deflation, depending on preferred pressure. Tubeless also allows single-digit PSI. Adventurous riders swear by tubeless. But most often, they carry a spare tube as backup.
On top of that, there's a movement towards the Clik Valve, essentially an adapter for the Presta valve for easier one-handed inflation.
In otherwords, users are tired of the finicky Presta valve. While I've had a lot of experience with Presta, I've always had a love/hate relationship with the system. There's a fine line with how much to unscrew the nut vs. seating the pump for optimal inflation without the risk of bending the top screw. The washer-type screw that locks the valve against the rim periodically loosens - necessitating tightness checks. And when a tube replacement is necessary, it's harder to remove/insert a tube with a 2" valve, plus keep track of the removable cap and screw!
Here's a simple explanation of the differences between both valves.
While Schrader has faded from the limelight, I've found it a better system for general use: commuter bikes, kids bikes, touring bikes, and for recreational riding, because a stronger valve stem is easier to deal with. Bike touring is a good example, nessecitating use of a small hand-type pump.
Araya rims, popular on early touring bikes and mountain bikes, were ubiquitous. All were equipped with Schrader valves. Those rims are still going strong today.
I asked our son why he built Presta rims on my bikes. It's because the rims came with pre-drilled Presta openings. That further explains their prevalent use. In the past, I've had bike shops drill out Presta rims to accommodate Schrader (back when I had one Presta rimmed bike), and there wasn't any loss of structural integrity.

| Pleasantly surprised to have Schrader valves on my newest bike, the Downtube Dyan! Go figure, on the narrowest, curviest rim of the bunch. |
The good news is there's plenty of Schrader tubes available, even in the older 27" x 1.25 size, because as everyone knows, it's fashionable to restore old bikes!
