Presta vs Schrader

[eSoCal]

Other than being European elitist bullshit... what’s the advantage of Presta valves? On more than one occasion the core unscrews with the dust cap and all the air blows out

 

[papab]

Mostly tradition. Maybe easier to pump. Not sure you can even get schrader tubeless stems. Every bike I own has presta, but I wouldn't complain if the industry went to schrader

I far prefer schrader because I can put an airline on them. Presta feel very fragile

 

[eSoCal]

I run tubeless, and next time I will look into schrader stems... then I can use my air compressor without an adapter... but most if all I will never again have a core unscrew when I take off the dust cap

 

[Doomanic]

What dust caps do you use?

Don't use dust caps, they aren't necessary. Tighten up the core a little more, they make a tool for that.

When I started riding as a kid, I wasn’t aware of Presta, just Schrader. I use Presta because that’s what my 2016 bike came with. Never really gave it much thought, as they are priced the same.

Presta for bikes, Schrader for cars.

 

[All4Fun]

Presta is for weight weenies, not for us ...

Almost all the bikes here have Schrader, if not standard, i'll drill them, rims are wide and strong enough.
Why? easier and faster to inflate and add sealant (tubeless), firmer, fancy caps.

 

[Doomanic]

You can get fancy caps for Presta too;

Usefull too;

Thats exactly the kind of crap I waste money on - damn you

Nukeproof, Muc-off and Peaty's tubeless valves now come with similar* valve caps

 

[CjP]

I love these ones. Can work with Cush cores as well.

 

[urastus]

I thought the obvious logical answer is a smaller hole in your rim. A hole in the rim is a weakness. Where the rim joins is also a weakness, and not surprisingly often where there is a buckle.

 

[Gary]

all 3 of your observations depend on construction.
and not all rims are constructed the same

They're probably just a reaction against American elitist bullshit...

On more than one occasion the core unscrews with the dust cap and all the air blows out

Yeah, we read about that happening a lot.

Oh - hang on...

Seriously, if you can't tell that you're unscrewing the core - which generally takes more turns than is needed to remove a dust cap (assuming the core is properly screwed in in the first place) - you probably shouldn't be allowed near a bike.

The bike industry just likes to swap between the two, my 97 Giant has Presta, 2003 Avanti had Schrader, 2019 GT has Presta. My race BMX’s over that time period were also a mix. If I’m the only one working on all our families bikes different eras as well Presta is fine. If they work on them Schrader, as they always bend the damn core.

Stans does Schrader tubeless valves last time I looked at mtbdirect if your up to drilling your rims, Park Tool has a video on doing it.

OK @Gary let`s see a tutorial on how to make a Schrader fit through a presta hole .

And yes I think Presta valves suck . The valve can be bent and or broken if the bike falls over during inflation while the pump is attached .

The small diameter of the Presta valve requires a smaller hole in the rim, whose size is important for narrow rims where cross sectional strength of is significantly reduced by a stem hole. In narrow rims, clincher tires also leave insufficient space between tire beads for larger Schrader valves.

Bikes all seemed to have Woods valves when I was a kid. What's wrong with them ?

 

[All4Fun]

If Woods is the same as Dunlop, than you can't check the pressure, because it's a one-way valve.

I think I remember them. You had to undo a collar to remove the valve? The only gauges those days were at gas stations or those pen like gauges; the rest of us, just thumb pressure . You could pump them up at gas stations if you held a few layers of handkerchief over the valve - a trick I've surprised others with in different circumstances.

You surprise me Gary, I would have thought you would have reached for the big gun

 

[Gary]

I ain't putting any effort into "searching" for anything pre 9am.

 

[Mcharza]

Presta for bikes, Schrader for cars.

Schrader also for tractors and wheelbarrows

 

[BeBiker]

I have Schader on everything with tires I own, so quickly converted the e-bike to Schrader.

I wish I could convert the other way - I prefer the smaller hole in bike rims

You can get reducers that fit in the rim to accept presta tubes, dont think they work with tubeless valves due to the hole size, although may work with a valve/rimstrip like a stans one.

Never had a problem with Presta, i appreciate they are potentially more fragile but only if you pull and bend with the pump. You see some people fighting the pump as if they are fighting a snake, i dont get it. Schrader (at least cheap tube) will fail just as easilly if you do that as they are rubber valve stems and your bending and pulling them in a sharp hole the rim. Used to get a ton of tube failures at the valve when i worked in a bike shop (yes it was Halfords, perhaps the bike quality might have had something to do with that )

Getting a reducer does not lessen the weakness caused by the larger hole - my preference is purely functional strength or minimising the weak spot. No hole would be ideal, but not possible...yet.
