I have Schrader valves on my tour bikes. It makes pumping at a gas station easy and convenient. 😊👍🏻
And odds are, any time you need a pump & for some reason don't have access, whoever has one has Schraeder. Loaned my Zefal floor pump & never got it back. Frame fit Presta works ok but may drill my rims.
A hack for cleaning the inside of valve stems if there is a leak. The brushes that often come with stainless steel drinking straws fit nicely.
I always carry a Presta to Schrader adapter, if I found myself without a pump. Air pumps at gas stations use Schrader. Car drivers also might have a pump in the boot.
I like Schrader valves. They are more versatile than Presta. All of my bicycles have them. Solid and reliable and you can fill your tires at any air station. Most air stations don't go over 80-90 psi, so you won't overfill your tire. I use a Zefal frame pumps, an hpX4 on my road bike and a hpX3 on my tandem and they do a good job, but you still need to top off the tire at a local station or bike shop, if you are on the road. At home, I use a Zefal Alaskan, with the dual valve head. It pumps the tires up to full pressure quite quickly.
You can't put a Schrader valve into a deep section carbon road rim, and into a skinny aluminium one at your peril.
Schrader valve is my preference for versatility
When I built carbon wheels for my mountain bike I had them drilled for Schrader. My city clunker currently has Presta but it's just because I got those tubes for free. I prefer the Schrader design for sturdiness and simplicity.
Schrader all day.... Seen those pos Prestas snap off with hand pump.
Cack handed
I put Schrader adapters on my presta valves. I know it sounds dumb but now I have the more universal Schrader valve to fill up on, and I can easily unscrew the adapter by hand so I can basically remove the core with no tools to fix flats.
Most bike stuff I see (even the pretty expensive stuff) still seem to be made for Schrader first, and then has some kind of adapter for presta, almost like it's some kind of fad they're waiting to pass? Idk, I'm sure they are better in some way that professional roadies and other weight wienies can appreciate but for the other 99.99% of people the more universally used Schrader is just as good if not better.
Schrader is better for most of the cyclists.
Have both, prefer Schrader
Here in Brazil always is a Pain to use the presta valve because during a Bike Packing any place had the structure to save without adapter. Due to this a couple days ago I have replaced the tubeless valve to Schraider.
I have Presta Valves currently. I will be converting to Schrader. I tend to bend the Presta cores. Also airing up using an adapter is a real pain. All the air stations are set up for Schrader. 😊
It's a technique issue. Here's how you solve that problem.
Instead of wiggling the pump head back and forth to get it off, grasp the pump body about 6 inches from the head and then smack the body near the head with your other hand so it pops straight off.
For floor pumps, you can grasp the head in your fist with the stem between middle and index fingers, then wrap your other hand around and press your thumbs against the rim to pull it straight off, or smack one hand with the other like you do with the frame pump
@@jm-um1tx yup, that solves a problem that doesn't even exist with schrader valves. Hmmm
@@davemeise2192 Hmm, well maybe you should do some research on the conditions where Schrader or Presta are appropriate. Because it sounds like you think that this is one of those brand loyalty things, rather than an engineering issue. For some uses, there are clear advantages to Presta, like with narrow rims and higher pressure tires.
I understand, though you can't know what you don't know, but usually, being clever is a hint.
A Presta valve takes air far more quickly by the roadside with a flat repair using a pump... you are doing something wrong if you can bend a Presta valve - all in the technique.
You guys aren't wrong. I agree there are benefits to Presta Valves. I have more reasons that I didn't include in my comment why Schraders are a better choice for me. The bike or rather ebike I'm converting to Schraders has 4.75 x 26 Fat Tires that are set up Tubeless.
The technique you're talking about I may not be capable of. I have disabilities that also affect my hands. I've managed with the Prestas for several years but have also replaced the cores because I bent them. No doubt it was me. I'm constantly worried about losing the adapters when I need to use Schrader air stations. I do carry a pump for emergencies but I'd rather not use it if I don't have to. I've done it but it is not fun. Thanks!
In sweden we have dunlop valves on our standardbikes. I can't understand why. Schradervalves are genius.
I have schrader on my hybrid and presta on my gravelbike. But I want to have schrader on both.
I genuinely thought that a Dunlop valve could only be found in a museum. That until I saw them in wide use on the streets of Stockholm…
The only right place for them is in a museum or on vintage bikes. If I do a youtubevideo about valves part of it will be why swedish bikers should start using Schradervalves/carvalves instead.
In the old days I recall Schrader having a little round nut at the base to secure the stem. I wish they still had that. These rubber push fit bases push in when you attach the pump if the inner tube is empty.
Schwalbe schrader bicycle tubes made in Vietnam still have these "THREADED COLLARS" .
I have two Norman Of England, Western Flyer three-speed bikes, that my parents got in 1957. They have the threaded Schrader valves. I may have to look into replacements sometime in the future.
@@johnandrus3901 The Schwalbe tubes from Vietnam plant should be ideal . I have 26 x 1.9 - 2.1 inch ones on my TREK 4300 - 2009 custom build seen at Google images - Fulcher's Cyclery in Panania ,Sydney , Australia .
@@robertmcfadyen9156 Thanks, I'll check them out. I could use a few spares, even though the bikes are mostly for display.
@@johnandrus3901 What do you think of my TREK on Google images ?
I have presta valves but carry an adaptor so I can use a schrader pump and also my fairly accurate car tyre pressure gauge. A couple of times, I've been fixing a puncture outside someone's house and borrowed their car pump.
Presta requires a smaller hole in the rim, and the rim is the thing keeping me rolling down a hill. Schrader can be more convenient if using a machine to pump the tyre, but on long cycles I only have a hand pump.
Thanks for this. I really don't know why presta is still so common. Schrader FTW.
Great video
Have both, plus Dunlop "Dutch" valves, but kinda prefer Schrader. But I also prefer to not drill into my 6 mm rims, so most of my spare tubes are Presta as i bought them in bulk with both my bikes in mind. I prefer to use adapters for the 8 mm rims over drilling out the 6 mm rims.
Drill in the rim is not nice, understand you there.
for years, I thougth that presta valves are better in higher pressure road tyres. but wait. there are huge trucks out there with scrhrader valves and 8+ bars of pressure.
nowadays I prefer the schrader, it's easier to keep clean and less likely to get bent.
Also all shocks that I'm aware of use Schrader values.
Schrader has a higher leakage rate than Presta. On a truck you have a huge air volume, so the leakage rate does not really matter since it is too small to have an impact here. A road bike tire however has a tiny air volume compared to a truck tire. The difference in leakage through the valve itself is noticeable here between Schrader and Presta.
Schrader is surely not a bad valve, both valve types have their pros and cons. One reason for Presta at road bikes is the valve hole is just 6,5 mm and not 8,5.
For my utility bikes, and bikes with wide rims, I have Schrader. For bikes with narrower or deeper rims, I have Presta. Horses for courses. I even have an old Raleigh with Dunlop valves (for period correctness), but they are a PITA.
In the netherlands like almost all bikes are dunlop. Personally i find it the best. I do understand the disadvantage of not being able to read the psi.
When I was kid most bicycles had Dunlop valve. I did not like it, because floor pumps were made for schrader. I had to pump tires with small bicycle pump. Then noext bikes hat I had, had scrader valves. I did not like them, because the quality of those valves were always so bad. They always leaked and the the knob was getting stuck. You get tire inflated, remove the hose, and then must have a nail or wire ready to lift the knob at middle to unstuck the valve, before all air escapes from tire. Well I guess it was because soviet union had bad quality valve cores.
Now I have presta. In general I like them a lot, but sometime I have trouble to open the tiny nut on knob to open valve. I tend to tighten it too hard with mu finger and then it happens that when I open it I unscrew the core also just a bit. Maybe a half of turn, but that's enough to create small air leak and then after a hour of riding I get pinch flat.
But still I like presta most. Next time when I buy a floor pump I try to find such that is compatible only to presta, because dual systems are annoying. I actually hate the schrader because the stupid automatic pump hose head will switch to wrong hole. It's not working like it's supposed. Also I hate the them, because when I had my traktor. A stupid car lover stole the good cores from my tractor tires, replacing them with bad leaking ones from his car. And how much work is to inflate tractor tires with floor pump.. And beside I hate cars. I don't want my bicycle to have same valves as cars, when there is a good alternative available.
Adressing your pump problem. Sounds like you dont need a new floor pump, just a new Pump Head, assuming your pump got decent enough quality. Try the SKS E.V.A. Pump Head. I also had the same problem with the stock Pump Head on my mid range SKS Pump. The E.V.A. one is really nice for Presta valves, but you can still use it on any other valve.
Have both but like Schraeder.
Wow🤯 never heard of that 😲 new tubes need replacement
I put flat out, seal it into my tire, but how likely is it that it will gum up the valve or at least make it hard to come out back it out.?
I don't have a personal preference per se, but in my country, it's Schrader valves in like 90% of bikes, so it's convenient to go with the flow and use Schrader valves myself
I have presta valves. I have no idea why the presta valve is becoming the standard on bikes when the good old schrader valve works completely fine and is alot less finnicky then the presta valve. If the schrader valve is good enough to use on cars from a Honda Civic to a McLaren hyper car I don't see why it would be a problem on bikes.
Becoming? For bikes beyond department store and entry level bike shop bikes presta are the most common and have been since I started cycling in the late 70s.
@@GreenCurryiykyk those are exactly the bikes I'm talking about. Now Walmart bikes are getting presta valves.
Because manufacturing is braindead. They were meant for road cycles not for mtb.
@@GreenCurryiykyk "But Mom, EVERYBODY'S doing it" is not a valid argument in favor. Popularity fallacy.
It's a little harder to find Schrader valved 700c inner tubes around here. My bike uses Schrader 700c so I have to stock up on spares when I can find them.
Narrow rims require a presta valve. Otherwise there is no reason not to use a Schrader.
I don't use Schrader or Presta, I use Dunlop valve stems. They're very popular here in Amsterdam.
I have prester valve ur thats because they are with the inner tubes I have
i have one of each an a bike or two. use a hand pump with both systems and have brass adaptors for prestas when I use an air compressor. presta holds air better in my humble opinion
The Dutch have a 3rd kind of valve which I prefer most
I have schrader and prefer that. Less hassle inflating tires than presta.
Presta but I’ve seen stans do schrader for tubeless
Love you Calvin
Both - Schraders in winter wheels, Prestas in all other three sets.
PS
This is probably a kind of Midas' barber syndrome - at the first virtual meadow I come across I had to reveal I have a separate wheelset for each season!
Schrader works just fine and is less finicky, not to mention it doesn’t require you to buy special equipment. Maybe presta makes sense on narrow road wheels, but it’s a pain in the ass on mtb
Nice, concise, informative video. 2:20 before COVID, you'd test it with spit . . .
I prefer presta because they look sexier. For fonction, I don't have a preference, unless I am touring, for versatility as another person wrote below.
Schrader, presta, either is fine, but when those dutch valves show up you know I'ma be mad hahaha
My touring and road bikes are all Presta, but the cores get bent easily. The cores on the tubes I bought are not removable.
Depends on the tube. Many are replaceable.
I use usb-C
This bike. Hardtail mtb has presta, my last 2 same, had schraeder. This model is top of the range.
Dunno, had no problem with presta so far but.... schraeder is more versatile, I can even use car compressor pump if need be. I guess I 'll have to think about it.
Well most decent wheelsets nowadays that are tubesless ready come with drilling for Presta valves, because most tubeless Valves are Presta. You can always drill a bigger hole in the rim to run Schrader (tubes), but you cant run a tubeless Presta Valve in a Hole with wider drilling.
I prefer schrader as I thing easier to inflate. Sadly all my 29er wheels are presta which are delicate when pumping
I hate those valves without the lock ring, the stem dissappears into the tyre .
Schrader value is most common in all vehicles
Schrader, and Presta, and Dunlop
Maybe it's just me but when I had Schrader valves I hardly ever added air. Now with presta I have to add air weekly
Schrader!
I use schrader valves
I prefer schrader
Me also
I prefer Presta on bicycles...and i'm a 40+ years pro motorcycle mechanic used to Schrader
Me too, but a big reason is that I prefer to use heavy duty rims that are more often schrader
i prefer dunlop valves
Schrader, I can use it with car accessories, or motorcycle ones. It doesn't hold air as well as presta, but I messed up valve core due to terrible adapters on schrader car pumps.
Also I am no fan of skinny road bike rims and tires.
Previously I've wanted a Schrader valves for a harmonisation between every other applications. But now I have a Reserve Fillmore tubeless Presta valves and I would prefer it everywhere instead of Schrader because it's a completely new valve compatible with Presta.
I like bike
shrader all the way
I use both, Schrader on all bigger vehicles and Schrader and Presta on bicycles. Presta has the advantage the leakage rate of air through the valve itself over time is lower, these tubes maintain the pressure for longer. This is especially noticeable on tires with little air volume and high pressure, like on road bike tires.
On mountainbikes the air volume is bigger and the pressure is lower, in this case only the width of the rim may demand Presta, since not all rims can have 8,5 mm valve holes.
Presta, presta, presta!
I have presta..but i prefer schrader.
Schrader valves all the way! Other than for racing and the so called advantages of a skinny presta valve reducing rotational mass and aerodynamic friction the Schrader valve does everything a normal cyclist needs. And a schrader valve type of pump and or tube is cheaper too.
I've used Schrader and I've used presta valves I honestly prefer Schrader
Schrader valves are much more durable. Even high pressure AC systems use them. Too many small flimsy parts in presta.
Question: What advantages, if any, do Presta valves have? Why aren't all valves Shrader, just for the sake of standardization?
I'm fairly sure I know this one...
Old road bikes used to have skinnier tyres, therefore a skinnier rim, So drilling an 8mm hole would be difficult on the thin rims (Thin in profile and thin in terms of the thickness of the metal).
They have also been seen on mountain bikes which I believe has come from DH bikes trying to maintain as much strength in the wheels as possible.
Either that's the reason or it could come down to cost, access to the valves, manufacturing location and place of invention... I read that presta was made by a Frenchman
The idea of a new valve called 'presta' may have resulted in a misnomer of it being superior too - Similar to new bike tech today. Presta has many different translations which may have made it more appealing.
I am join your assistant 😟💪
Prominent
Well im European, so I guess I go with Dunlop. Jokes aside, my Tubeless Setups run Presta and on my commuter Bikes I run a mix of Dunlop and Schrader.
Schrader valves seem way better, what's the advantage of Presta?
Hello Bonjour , moi je préfère le système presta 😊 Merci Calvin 😊❤
Me too.
Schrader! Presta is a pain in the b*tt.
I like my Dunlop valves.
NO LOVE for Dunlop 😆
That needs its own show!
I will stick to Presta,thanx.Never had any issues
I haven’t got 10 minutes to watch a video about Schrader valves
This is under 3 minutes.... so you're in luck?
have both, prefer Schrader - its just easier all round. (no, i wont be arguing with fanboys of either type)
Dunlop if I can choose. Presta on my roadbike, Schrader on my car and on the heat pump, but thats one size bigger😃
I have Presta on my current bike, but I prefer Schrader. Still not quite sure what the value is of Presta, honestly.
Presta. Except, no, Fillmore.
I am not exactly a fan of drilling presta valve holes out to schader size due to the risk of sharp edges or burrs . Sometimes people had done this so that they can fit a budget tube in leiu of the more costly correct one .
You just need to deburr the hole after drilling.
I thought you'd tell us who invented it and his name was Schrader.
Не вижу никакой принципиальной разницы в использовании Престы или Шрёдера.
schader all day - wish the presta was ditched ne even banned from cycling only use is stupidly thin wheels when they didn't know better that it wasn't the way to speed.
It's not the Schrader valve
I converted all my bikes to shrader. Presta sucks.
There's adapters available for presta (simple ones are not convenient). Mr stubby (good for as internal thread adapter) and covertair (only for threaded surface). I wanted to buy but shipping is way too expensive for me. I had to make my own permanent adapter. Overall i advice drilling the rim and using Schrader tubeless or tubed. I just have procore. Presta is just bad for multiple reasons. Yes manufactures can use it but thry must include adapters, but nobody bothers.
Another thing. If you into aesthetics, even on a 29er, Schrader just look crap on a bicycle....
Presta valves are an abomination. Weight gain with Presta is less than a drink of water. On most rims drilling out does not compromise strength. Prestas are still needed on some high performance deep rims (think carbon) because Schraders don’t come long enough. Carbon rims should not be drilled out because of the fragility of the carbon. Schrader. Would like to know why someone decided to reinvent the wheel with Presta valves.
Prestas are stone-age crap.
Presta is gay, Schrader all the way.
Homophobia is the gayest thing of all.
I actually use a bicycle pump to keep my CAR tires inflated (I check them monthly, so only a few strokes are needed). So Schrader for car, hand truck tires (an expensive but nice Magliner), and yes, I've drilled out all my bicycle rims for Schrader! Sorry, Presta is just a pain in my opinion.
Presta is happy and carefree?!
@@mattgies No, presta likes to take it in the butt
I have schrader valves on the bike I use most. I have yet to see any real reasons for using presta, except perhaps if the rim is extremely narrow.
