Pros & Cons of presta valve vs schrader valves

[Flowrider]

A question I've wanted to ask for a while now. From a personal point of view, what have you found to be the positives and negatives of these two valves?

What would your preference be?

Schrader are easier to work with. They let out air easier also.

Presta are more troublesome to work with, but are the more secure valve.

The gold standard now is Presta because it is smaller more aero dynamic than Schrader valves in the past but there has been a lot of advancements now that make the weight issue and "air secureness " null between the two valves, I think the bike industry just stopped adopting the changes at this point and decided to stick with presta as the more premium option available to mid to high end wheel sets.
Personally I'd like to have an option to have access to gas station pumps in times of emergencies without having to screw in adapter, but until the whole industry adapts Schrader and makes it use available to even the top tier stuff, I'll stick with presto for now

Thanks for that. I agree with the fact that we can go to a garage and pump our tyres with a Schrader without a problem. My experience with a Presta is that it brakes a lot easier. I've never had an issue with either leaking from the inlet.

Car, motorbike and bicycle tyres with the same valve make sense to me. I can't see an obvious advantage of the Presta over the Schrader

My fat bike thankfully came with Schrader valve tubes and rims. When I went to buy emergency backup tubes, they only had them in Presta valves. Fortunately, these Presta tubes still fit my rims, and I just carry a Presta-to-Schrader adapter for pumping air.

That said, I’m always a bit nervous pumping air into a Presta valve because it feels flimsy, and I worry I might break it or cause a leak where it connects to the tube.

One big advantage I’ve noticed is that a Presta tube will fit a Schrader rim/hole, though I’m doubtful the reverse is true.

Plus, the fact that I can pump air into my Schrader valve almost anywhere without needing an adapter is a huge convenience compared to always having to carry one for Presta.
