A4: I need to switch the nozzle at the end of my lezyne pump.
By the way have you heard of schwalbe click and whatever BBB called theirs?
More brain damage, don't thank me
@bobjonkman @CharlesSites @bikenite
@jfparis @ascentale @bobjonkman @CharlesSites @bikenite
I'm not convinced by either unless you run tubeless and need the extra flow rates they promise
@ascentale @bobjonkman @CharlesSites @bikenite A4 #BikeNite when I was younger I preferred Presta because of the easier pump head on/off, but nowadays I prefer Schrader for its durability. Presta also lost favor because my favorite portable pump (Lezyne) screwed on regardless.
@ascentale Schrader all the way. Presta needs an adapter to work with some pumps and with the typical car tyre pumps at service stations. My wheels aren't so thin to require Presta, so it's just a disadvantage. Though for some reason my fatbike of all bikes has Presta valves???
But as long as it's not Dunlop. :D
@ascentale @bobjonkman @CharlesSites @bikenite
A4. I hate Presta. I feel like they break more, are generally harder to use and I generally don't understand why they come with bikes like mine. Things I want out of a bike: sturdy, low maintenance, can refill tires easily anywhere.
Presta is not that.
@thesquirrelfish @ascentale @bobjonkman @CharlesSites @bikenite I kind of love them, but it has to be a tire with removable valve core. Very seldom problems, the seal/ mechanism appears better protected than Dunlop. But sure, you have to be careful not to bend them
@likse @ascentale @bobjonkman @CharlesSites @bikenite yeah I'm not good at being careful. My bikes have to be tough! Like they're going to be rattling around in storage under a bus, have some sort of incident where a sleeve or skirt is going to get tangled in the wheel, be thrown down on the grass as I run towards something, be in a pile of like 4 other bikes we're squeezing into one lockable thing with creative use of chains and u-locks...
And then I'm going to be hurriedly topping off a somewhat flat tire when I'm already late for work...
@thesquirrelfish @ascentale @bobjonkman @CharlesSites @bikenite yep a different use case, i like to ride long distance in just about any weather and am pretty stubborn about getting the pressure right, so pumping tires is the least of my concern, I treat the bike like a baby at home and rather rough on the road
@ascentale @bobjonkman @CharlesSites @bikenite A4: don’t much care, though I think I’ve only got one bike out of ten or so with schrader. Once I started having road bikes & similar, it made sense to mostly have one type, so when given a choice I go with presta. I do break a lot of valve cores, though. #BikeNite
@ascentale @bobjonkman @CharlesSites @bikenite A4. No thoughts on "versus", who cares, it's a technology, is all.
I use Presta, it took longer than it should to learn how not to bend the stem. I am slightly interested in Cliq but worry they will clog with tubeless sealant in new, interesting, and expensive ways.
@ascentale @bobjonkman @CharlesSites @bikenite Does anyone use Italian regina? Does anyone got experience using Schwalbe click valve?
@ascentale @bobjonkman @CharlesSites @bikenite A4. My rims take presta, the trailer takes schrader, kid's and mom's bikes take shrader. My pump can do either with minimal setup/no adapters, so it's really not something I think about.
Weak personal opinion: presta is a little easier to use since there's not a cup to fill up with road gunk when the cap inevitably disappears and the stem nut is nice to get a flat pumped up. But vavles aren't something on my mind very often.
@edd @ascentale @bobjonkman @CharlesSites @bikenite Schrader caps? I've definitely had more lights stolen – from forgetting to remove them myself – than valve caps. Which would be presta.
@thematic @ascentale @bobjonkman @CharlesSites @bikenite Not stolen, just small cheap plastic parts doing what small cheap plastic parts do: crumble or roll off into the darkness never to be seen again.
@thematic @edd @ascentale @bobjonkman @CharlesSites @bikenite Mine just kinda wander off on their own. LIke, forgetting to put them on and until one really got gunked up I didn't care. Now I've had some success in Remembering To Put Them ON. Hypothetically I shouldbe saving them when I replace a tube :P
@ascentale @bobjonkman @CharlesSites @bikenite A4. I prefer schrader. I can pump up at any gas station. The hand pump I carry with me is not that strong, but I can inflate enough to ride to a gas station to do the rest.
Presta (or French Sclaverand) is on my other bike and pretty common in Europe too. I find it pretty reliable. I use to carry an adapter with me in case I need to pump up at a gas station.
Dunlop is the valve of my childhood. I had several defects, so I don't like it anymore.
@ascentale @bobjonkman @CharlesSites @bikenite Both suck in their own ways. Clik valve is the winner.
@f09fa681 @ascentale @bobjonkman @CharlesSites @bikenite As Clik valve by Schwalbe is pretty new. What are your experiences? Why do you prefer Clik?
@realSiegfried @ascentale @bobjonkman @CharlesSites @bikenite It's the convenience factor for me. Pump head on, pump, pump head off. No need to fasten anything, no need to losen a screw, no worrying about bending the thingy. And you can use pump heads for presta valves if you don't have the clik pump head available.
The only annoying bit is that my SKS mobile pressure gauge is not compatible (the presta head doesn't push down the pin when measuring which would be necessary). If someone has a hack... I'm interested!
@f09fa681 @ascentale @bobjonkman @CharlesSites @bikenite Sounds good. Plus an adapter to fill up at gas stations (or use of existing pump at home) could become my preference.
@realSiegfried @ascentale @bobjonkman @CharlesSites @bikenite Yes, there's a kit with a pump head adapter that can be used for Schrader pump heads.
I don't have special pump heads, so I'm always using that for my stationary pumps at home but also the ones I take with me on longer tours.
@ascentale @bobjonkman @CharlesSites @bikenite
A4: Neither. I have switched all 6 bikes in my family to Clik valves.
It is just much easier to handle for everyone.
@ascentale @bobjonkman @CharlesSites @bikenite A4.
Schrader valves just feel crude & rubbish. Best left on cars & tractors. Go team Presta.
Warning. No science or objective reasoning was involved in formulating this opinion.
@ascentale @bobjonkman @CharlesSites @bikenite A4 #BikeNite I'm happy with presta, save for the odd blockage which is usually pretty easilty sorted. I am curious about the new generation of alternatives though, and we do seem to be going through a boom time for those.
@ascentale @bobjonkman @CharlesSites @bikenite Just [re]found the link I meant to include in my #BikeNite reply with a nice round up of the current state of 'alt valves': https://bikerumor.com/get-pumped-the-alt-valve-revolution-is-upon-us/
@ascentale @bobjonkman @CharlesSites @bikenite
A4 I much prefer presta. Never broken a valve core. Don't use tubeless, so works for me. I always hated the old (80s) screw on pumps for Shrader valves that let all the air out as you unscrewed them so when I discovered Presta it seemed a better design to me.
@ascentale @bobjonkman @CharlesSites @bikenite A4. I’ve had both, schradar always seemed sketchy with the rubber valve stem, presta seemed more robust. Not wanting to have two pumps, I just kept with presta on my bikes. That is no longer an issue with pumps that can handle both, if they were a thing back then maybe I wouldn’t have chosen presta.
I’ve heard of issues, but I’ve never had any with either kind of valve or stem. #BikeNight
@ascentale @bobjonkman @CharlesSites @bikenite A4. I hate Presta valves. Simply because if I want to fill up my tire at a gas station, it's going to be Schrader. #BikeNite
#BikeNite A4: I've almost always had Schrader valves. They used to have external threads on the stem right to the tube, and a skinny nut to hold it at the rim. But new tubes have rubber halfway down the stem, and I always think it'll get sliced open by the valve hole edge.
I get Schrader valves for new tubes because I can inflate them anywhere.
And after rabbitholing valve types for the last hour, I've learned that my bike in Holland had Dunlop valves.
Q4. What are your thoughts about presta vs schrader tire valves?
I use whatever came with the bike until it wears out. But for replacements, I strongly prefer Presta. I've seen videos where people had problems with them breaking but haven't experienced that myself.
The new Schwalbe Clik Valves look interesting too.
@ascentale I have both. The one advantage for the Prestas is that they don’t submarine into the rim if the tube is really low on air.
@ascentale @bobjonkman @CharlesSites @bikenite @bikenite #bikenite
A4. (1) What about the 3rd type (Woods/Dunlop), most common on Dutch and some similar old-school Indian and Chinese bikes? (I haven't used them enough to have an opinion.)
(2) I prefer Presta valves, but on my touring bikes, drilling the rims for Schrader and using Presta adapter inserts lets me use whatever tubes are locally available. Carrying adapters that fit over the Presta valves lets me use gas-station air pumps.
@ascentale @bobjonkman @CharlesSites @bikenite #bikenite
A4: p.s. One advantage of Schrader over Presta that I hope never again to need is that it's easier to put slime or similar sealant into tubes through Schrader valves:
@ehasbrouck @ascentale @bobjonkman @CharlesSites @bikenite
This
https://www.parktool.com/en-us/product/valve-core-tool-vc-1
...plus this
https://www.parktool.com/en-us/product/tubeless-sealant-injector-tsi-1
... makes it really easy to put sealant and impress the valve. I would not want to try to shove sealant pasta Schrader valve core.
@morgan @ascentale @bobjonkman @CharlesSites @bikenite - Maybe I didn;t have the right tools, but I've found it easier to remove Schrader valve cores that Presta cores. YMMV.
@ascentale @bobjonkman @CharlesSites @bikenite I have never owned a bicycle with anything but a Schrader valve, and I don't plan on ever owning a bicycle with anything but a Schrader valve. The Presta valve offers zero advantages.
@ascentale@sfba.social @bobjonkman@mastodon.sdf.org @CharlesSites@hoosier.social @bikenite@fedigroups.social A4: I use both, and I don't have a strong preference. I do think it'd be more convenient if the valve type could be standardized, though. #BikeNite
@ascentale @bobjonkman @CharlesSites @bikenite A4. #BikeNite Presta for me. My very first MTB had schrader and they would clog and get very slow leaks when the pin didn't come back out. On one long group ride I was constantly stopping to add air. I was done with shrader after that.
I like being able to screw down the presta valves. They bend if you aren't careful, but that doesn't usually cause problems. They are easily and cheaply replaced. Maybe only certain tubes allow that, but I run tubeless on my mtb and being able to remove the valve core and replace old ones is a key feature. I carry a little shrader adapter so I can use normal pumps, if needed.
I have had some issues with mtb team kids who pumped up their tires and then didn't tighten down the presta valves tight enough and ended up with a slow leak. That can be difficult to diagnose. I've also had presta valves where the screws were so tight or clogged that I needed to use pliers to loosen them. I carry a multitool with mini pliers as a result. Some rims will only accept thinner presta valves.
Some of the new valves, like Clik Valve, look interesting, but I'm not sure I need anything that fancy.
@ascentale @bobjonkman @CharlesSites @bikenite a4 #bikeNite I prefer presta, not really sure why, I wind buy a shrader tube, but won't bin one until it dies.
@ascentale @bobjonkman @CharlesSites @bikenite
A4. I prefer presta. Partly just out of habit, but since the advent of tubeless, it’s now my default.
Some of the new solutions look interesting, esp. for tubeless but I’d want to see more adoption.
@ascentale @bobjonkman @CharlesSites @bikenite
And speaking of new solutions, I find this interesting. It will need some watching to see if there is broader adoption.

@MrBirch@beige.party @ascentale@sfba.social @bobjonkman@mastodon.sdf.org @CharlesSites@hoosier.social @bikenite@fedigroups.social You got me curious. How do you add sealant to tubeless tires through schrader valves?
#BikeNite
@daihard @ascentale @bobjonkman @CharlesSites @bikenite @MrBirch Schrader valves are the standard on motor vehicles, and most motor vehicles are tubeless. You add sealant to them the exact same way as you would on a car.
@gcvsa@mstdn.plus @ascentale@sfba.social @bobjonkman@mastodon.sdf.org @CharlesSites@hoosier.social @bikenite@fedigroups.social @MrBirch@beige.party Use sealant in car tires? That's completely new to me. Is that a common practice?
@daihard @gcvsa @ascentale @bobjonkman @CharlesSites @bikenite @MrBirch a lot of cars these days come with a can of sealant instead of a spare wheel
(how you're supposed to inflate the tyre after sealing it, not sure ...)
@dan@axillae.telent.net @gcvsa@mstdn.plus @ascentale@sfba.social @bobjonkman@mastodon.sdf.org @CharlesSites@hoosier.social @bikenite@fedigroups.social @MrBirch@beige.party I had no idea. I bought my current car 5 years ago, and I've never had to look inside the trunk for a spare tire, but maybe it's not there!
1 more replies (not shown)
@dan @bikenite @daihard @gcvsa @ascentale @bobjonkman @CharlesSites @MrBirch the sealant can also inflates. It's a bigger version of the bike ones from Zefal or others. Plus cars often have pumps in the boot / trunk.
@daihard @ascentale @bobjonkman @CharlesSites @bikenite
I’ve never seen tubeless schrader valves. Until I just searched for it, I didn’t know they existed. But, judging by random searching, I’d say they are a minority.
Like presta, you can remove the core.
@MrBirch@beige.party @ascentale@sfba.social @bobjonkman@mastodon.sdf.org @CharlesSites@hoosier.social @bikenite@fedigroups.social Thanks. I'd have thought mountain bikes used schrader valves, but I must be wrong!
@daihard @bobjonkman @CharlesSites @bikenite @MrBirch Yup, one of the sealant containers I had came with a schrader core removal attachment. Made of plastic, so not durable, but it still worked.
@ascentale @bobjonkman @CharlesSites @bikenite #bikenite #biketooter I have learned to handle the Prestas on my fast bike and I appreciate the high pressure fastness.
I also learned to put those valve caps on the Schraeders so things didn't get so grungy the pump wouldn't seat :P
@ascentale @bobjonkman @CharlesSites @bikenite
#BikeNite A4:
Four of my five bikes have Presta, one has Schrader. I just prefer Presta because that's what I deal with a ride most. The one with Schrader, my Brompton, is a bit problematic as with the narrow space between spokes, I can't use my usual pump head, and the one I have that works is a pain to screw onto the valve. I need a better pump head for that bike. Suggestions?
@MartyCormack @ascentale @bobjonkman @CharlesSites @bikenite I solved this specific problem by having a couple of unusual Brompton wheels get made up and drilled for Presta tubes but I don't think that's a course of action that makes for a helpful suggestion.

@ascentale @bobjonkman @CharlesSites @bikenite #BikeNite A4. I have a lot of Presta tubes (road bikes, "higher end" MTBs of their era all Presta). Schrader seems to be more robust, especially with the dangly pin and long shafts of the Presta tubes. But I wouldn't convert them/etc. They are a lot chunkier, lol.
@ascentale @bobjonkman @CharlesSites @bikenite A4) had multiple cases of Presta valves slowly leaking air - only way to reliably fix this was to swap the valve.
Schrader valves work with gas station car tire inflation stations. At least they used to. Newer "smart" tire inflation stations can't deal with the low amount of air in bike tires and I heard storys of exploded tires and gas stations forbidding inflating bike tires.
> Presta valves slowly leaking air - only way to reliably fix this was to swap the valve.
How can you swap the valve without replacing the entire innertube?
Asked by someone who knows only Schrader valves...
@ascentale @CharlesSites @bikenite
#BikeNite A4
@bobjonkman @stereo4x4 @ascentale @CharlesSites @bikenite Just adding to others' replies: not all tubes have removeable cores.
@bobjonkman @ascentale @CharlesSites @bikenite see attached picture stolen from this website: https://bikebuildtt.com/es/producto/presta-valve-core-replacement/
Ah. A Schrader valve pin can also be removed by unscrewing. I have a handy valve cap with prongs on top to unscrew the pin.
This cap is out of my SCUBA kit. My float'n'flag has a car trailer innertube with a Schrader valve. It's much easier to deflate after a dive by unscrewing the pin than trying to hold the pin down to deflate the tube. I also have a Schrader inflator that connects to a hose on my regulator. 200psi FTW!

@bobjonkman @768kb @stereo4x4 @ascentale @CharlesSites @bikenite #bikenite
A4 I like Presta because of the nut that keeps the valve from submarining into the wheel (as someone else also mentioned).
But on the other hand, I hate that most Prestas don't have removable cores, so if you live in a goathead wasteland like I do and need Slime, you have to do a lot of tube research to make sure you buy the removable kind. With Schraeder they're all removable.
Also I wish Prestas weren't so loooong.
@akkana @bobjonkman @768kb @stereo4x4 @ascentale @CharlesSites @bikenite if you hunt, you can find Schrader tubes with threaded stems and a nut.
Ditto for Presta tubes with short stem lengths.
But yeah, you have to hunt for them, they are hard to find.
@cainmark @ascentale @CharlesSites @bikenite those "smart" inflators don't work well with car tires as well at least from my experience. They are not accurate and prone to "user error", e.g. I managed to get one into a state with the air compressor running/making noise but the tire pressure dropping more and more until there was nearly no air left in the car tire.
Some gas stations have a bike air pump behind the counter, so asking for one doesn't hurt.
@ascentale @bobjonkman @CharlesSites @bikenite
A4: if you want TPU tubes, finding one with a Schrader valve is an exercise in patience, determination, and paying lots more than the average TPU/Presta price.
@ascentale @bobjonkman @CharlesSites @bikenite #BikeNite A4: I never liked Presta valves. My G-Line had them and I replaced them after a few months.
I'm ok with Dunlop valves (were the common bicycle valve in Germany back when I was a teenager) and Schrader valves — most of my cycles of the past 2 decades had Schrader valves. Schrader valves can be filled at most gas stations.
I recently started switching to Schwalbe's Clik valves, so my 2 most common bikes are already converted, more to come.
@ascentale @bobjonkman@mastodon.sdf.org @CharlesSites @bikenite
A4. One bicycle has pasta. The other Schrader. I use presta to Schrader adapters on the presta valves. It's easier to me to inflate Schrader with my pumps and a fuel station in an emergency need air for tires situation.
@lopta @ascentale @CharlesSites @bikenite
Weird autocorrect I didn't catch.
@cainmark @ascentale @CharlesSites @bikenite I shall call them that from now on. 😄 #BikeNite
@bobjonkman @CharlesSites @bikenite A4. I have bikes with both! I don't have a big preference though I feel like I've broken more presta valves by fatiguing that little threaded part by wiggling it with a pump head.
Maybe that just happens more often because we have more tubes with presta valves. I think presta valves look better, but that's just a personal aesthetic thing.
@ascentale @bobjonkman @CharlesSites @bikenite I think presta requires a wider rim. That's why you will find Schrader (Sclaverand) on racing bikes.
@ascentale @bobjonkman @CharlesSites @bikenite S'funny, I do too. I like the thinness. But it's still "yep that's a valve" xD
I suppose it matters on particularly thin wheels too, of course. Might on mine, I dunno one way or the other.
@moira @ascentale @bobjonkman @CharlesSites @bikenite #BikeNite A4 follow-up: Funnily, Brompton has (or at least had) thicker Schrader valves for the narrow 16x1. 35" tires of the classic 16" Bromptons and thinner Presta valves for the wider 20x2.1" tires of the 20" G-Line.
@ascentale @bobjonkman @CharlesSites @bikenite
A4. Ya know, I think I'm kind of indifferent! They each have their pros and cons. I've had bent pins and related troubles with prestas, but it can certainly be easier to get a pump head seated right on them. My bikes use a mix of both.
@ascentale @bobjonkman @CharlesSites @bikenite A4: I'm on Presta because that's what my wheels use. I don't have a strong preference but I feel like the ability to tighten the valve by hand (and then put on a cap) makes slow valve leaks due to misaligned pins less likely? But I don't actually know that to be true.
It's not a big deal for me, my pumps handle both and if my wheels came in Schrader I wouldn't change it.
@moira @ascentale @bobjonkman @CharlesSites @bikenite only tighten presta valves with one finger. Too tight and you will destroy the rubber seal keeping the air in. I've had to replace many tubes because the non replaceable valves wore out and started leaking. Note that with removable cores, it is all too easy to loosen them over time with weekly unscrewing for inflation. Tighten them at least once a year!
@trouble @moira @ascentale @bobjonkman @CharlesSites @bikenite Interesting. Never seen that myself. Even with 20+ years old valves.
@realSiegfried @moira @ascentale @bobjonkman @CharlesSites @bikenite It's possible that I got some dust/grit in there, I don't know. but the rubber definitely had a "line" indentation where the rubber met the seat. #BikeNite
@moira @ascentale @bobjonkman @CharlesSites @bikenite
A4. Yes, all my rims accept Presta only. I've done bent cores on more than one occasion. I carry spares on the tourer now.
Still looking for a good frame pump option that fits easily on the valve, doesn't leak while inflating and doesn't take the core with it on removal
@oheso @moira @ascentale @bobjonkman @CharlesSites @bikenite I find pumps with short rubber tubes are easier to keep from leaking during inflation, but my current Lezyne compact pump on a 700cx28 tire only reaches 80 of my desired 100 psi, so I now carry an electric pump. #BikeNite
@oheso @bikenite @trouble @bobjonkman @CharlesSites @ascentale @moira Agree. Pumps w/ flexible tube that screws on are the way to go with presta. Rigid pumps that lock on, where the push & pull motion is orthogonal to the valve stem, is brutal on valves.
I prefer Schrader, but my workhorse have Prestas.
Would love to see TPU tires with Schrader.
@oheso @moira @ascentale @bobjonkman @CharlesSites @bikenite
A3 I use a Zefal sp3, Topeak Morphie and Topeak Rocket on my bikes. Rocket is smallest and is in a bracket attached under bottle cage. Sp3 is limited to steel frames and I've folded one up in the past. Morphie is probably the best pump but the frame mount options not great so best thrown in a pannier.
@oheso @moira @ascentale @bobjonkman @CharlesSites @bikenite
No expert here but personally I've found the adapters that you screw onto the valve work better than ones that come with the pump.
@ascentale @bobjonkman @CharlesSites @bikenite A4. I have no thoughts, other that schrader is what’s been on the tubes on my bike for a long time now! 😀🚴♀️❤️
@ascentale @bobjonkman @CharlesSites @bikenite A4 I have no strong opinions about either.
Is this like a vim/emacs, pepsi/coke, windows/mac thing? Am I going to be exiled for not taking a side?
@yantor3d @ascentale @bobjonkman @CharlesSites @bikenite well yes you will be, the answer is obviously Nano
@Pionir @yantor3d @ascentale @bobjonkman @CharlesSites @bikenite The hard guys prefer edlin valves anyway.
@Pionir @yantor3d @ascentale @bobjonkman @CharlesSites @bikenite quite right. Vi valves are only for those who enjoy self flagellation.
@ascentale @bobjonkman @CharlesSites @bikenite A4: I have bikes with Presta and with Dunlop. Both are fine with me. I kind of like the minimalism of Dunlop, where a complete overhaul of the valve involves just pushing a fresh piece of tiny tubing onto the inner stem.
#bikeNite
@fgbjr @ascentale @bobjonkman @CharlesSites @bikenite modern Dunlop have a ball bearing valve instead of the rubber so last longer but when it gets crud in, it's dead I prefer them on my city bike
@mjr @fgbjr @ascentale @bobjonkman @CharlesSites @bikenite Most of the Dunlop in my childhood used a ball. But nevertheless they also got leaky.
@realSiegfried @fgbjr @ascentale @bobjonkman @CharlesSites @bikenite yes, even the ball Dunlop valves still have at least one rubber seal that eventually perishes. Better is not perfect.
@fgbjr @ascentale @bobjonkman @CharlesSites @bikenite Dunlop seem to be more popular in Japan than elsewhere these days. (Can't swear about England.)
@oheso @fgbjr @ascentale @bobjonkman @CharlesSites @bikenite #BikeNite A4 follow-up: Yep, back in my youth there weren't Dunlop, Schrader or Presta valves. We called them the bicycle valve (Dunlop), the car valve (Schrader) and the French or the road-bike valve (Presta). I think that explains a lot about their distribution in Germany back then.
@xtaran @bikenite Today's the first day I'd even heard of Dunlop valves. I had to look it up to see a photo. https://en.wikipedia.org/wiki/Dunlop_valve #BikeNite
#BikeNite A4 follow-up: Thanks @meganL, this comment made me realise how uncommon Dunlop valves seem to be in some markets. So far they seem to be common in Germany and Japan. (Thanks @oheso for that information.)
Citing from the Wikipedia article you linked: "[The Dunlop valve] is a type of pneumatic valve stem in use in many countries, including Japan, Korea, India, Pakistan, Sri Lanka, most European countries, and a number of developing countries."
Probably not France though.

@xtaran @oheso @fgbjr @ascentale @bobjonkman @CharlesSites @bikenite I fully confirm. Dunlop was simply everywhere during my childhood in Germany. My first Peugeot in 1979 had Sclaverand, which was exceptional for a non-racing bike. The next step were when Schrader became common, because you could ride to the next gas station, although their early pumps did not go farer than 3 bar.
@xtaran @oheso @fgbjr @ascentale @bobjonkman @CharlesSites @bikenite Btw. Pump heads in Germany noawadays can handle Presta, Schrader and Dunlop.
