I could be tempted to try the cores as the full valve kit seems a bit steep.
They do claim to increase flow by "1.5x" which TBH it's a huge amount Vs taking the core out entirely to seat a tyre...
The thing that appeals for me is avoiding sticky/bent valve stems, and they don’t seem that dear (though there might be hidden costs eg. replacing tubes with ones where I can swap the valve cores).
But I don’t know about real world use.
Berm peak express recent review might be of interest:
I've recently installed some on one of my bikes,all good so far .On paper they seemed like a good idea to me .They worked with my non screw on presta pumps which is nice and the clik valve adapter that came with the kit I got works with my little Lezyne pump I have which is a screw on type and makes the pump much easier to use now. Only a few ides with them so far so time will tell.They are very easy to use.
Is there a UK distributor or only direct from the US? If so, is the postage expensive?
@tthew As this is a Schwalbe/SKS benefit, it’s Germany (or more realistically China).
Ison distributing in the UK- looks like they've got the valve cores but not the pump heads, helpfully
As this is a Schwalbe/SKS benefit, it’s Germany (or more realistically China).
Ah, OK. OP's link goes to a US site. I'll look for a European supplier. I'd like to get a couple of pairs of cores and a pump head as I have two track pumps, convert one.
I posted on here and got a bollocking as I sell them. They are fab imo!
Oh damn, sorry pal, I just ordered some from Tredz. 17 quid for a pump head and cores, 6 quid for a pair of cores.
That BPE video title & thumb is 1000x too clik baity so dismissed it as 'not interested'.
The cores, maybe, if they become standard and widely adopted.
do presta pressure gauges still work with the clik valves?

Apparently you can inflate with a Presta head pump (as long as it’s not a screw-on head) but the gauge isn’t accurate.
Interesting.... you don't actually have to use the adapter.
I'll reword it, will a stand alone gauge such as the Topeak smart D2 gauge work?
@ogden Is it really just a modified Woods/Dunlop valve?

I assume unless you’ve put an adaptor on it, no?
I also assume that SKS will expand their range of pumps etc as at the moment it’s floor pumps or adaptors.
Had a play with them, my one issue is that they can still clog as there's still a core in there (it hasn't happened yet so the jury's out but there's potential) when you compare to muc-off s big bore valves which has no core, just a tap. Been using those for longer and not clogged yet
No the Topeak pressure gauge doesn't work with them .
Do pumps and gauges work correctly if you use the adaptor? Not keen to use anything that messes with that functionality otherwise, everyone ends up borrowing a pump sooner or later, but if you can just throw the adaptor in your bag and keep 100% compatibility then that's pretty cool.
Can't help but be a wee bit skeptical of their breezy assurances about the head's compatibility with "legacy" pumps, my experience is that there's loads of different variations on fitment out there, I can't see any way a single head is universal. But they don't really lay out any requirements.

It's basically showing how mechanically inept some people are.
Dunno how they manage to change gears or get saddles/bars/stems installed without destroying them.

Presta are indisputably; definitely, unquestionably $hit. The industry has spend 20 years dancing around the subject but because roadies and "tradition" we just don't seem to be able to shake the damn things. Now even road bikes have evolved to rims wider than 20mm can't we all just start using schrader valves on bikes?
So many new standards trying to solve a problem that shouldn't exist.
Is it a pride thing?
Aaaah, another one who can't tighten a thread or pull a press fit off in a straight line. 😉
Swoon.
Add me to the list of incompetents as well then. I bow down to the superiority of our mechanical infallibles

I stand by my comment last time this was discussed. It doesn't matter how mechanically competent you perceive yourself to be, presta valves are breakable in multiple different ways and it's a simple matter of entropy as to when the end snaps off or comes off with a pump.
There's no reason for the industry to be sticking with presta other than that a schrader valve doesn't fit through a 100year old roadies rim.
Reasons I'm still running presta:
- tubeless means actually having to inflate an MTB tyre with anything other than a decent track pump is a very rare occurrence in the last 20 years.
- you can't get quality tubes with schrader valves
- quality rims aren't drilled for schrader valves
- however breakable the valves are, they're at least cheap to replace. Except Shimano tubeless valves, which are stupidly expensive, required to fit their rims, and lack replaceable cores!
There are no benefits to presta valves, they're just the lowest common denominator (thinnest) and therefore get used everywhere.
Seems like they are pushing these all of a sudden....
+1 for Presta being shitter than Schrader with essentially no redeeming features in the modern world. I don't care if you've never broken or bent one, neither have I but it happens and you don't have to be stupid to have it happen, you can have a moment's inattention or have someone else "help" with your bike. And even if that never happens, they clog, they're more delicate, they're more restrictive for tubeless, they work on less pumps and fittings than schrader does.
The only real world advantage is that it's easier to spell. Oh and I guess it enables people to sell £20 valves and £50 inflators.

These are always the arguments and I do agree, however, if DT Swiss made wheelset A with a presta hole and also made it with a schrader diameter hole people are still going to buy the presta one purely down to the stigma that only cheap bike products come with schrader valves or worrying about resale value etc.
Wow never really knew people got so disproportionately cross about presta valves. Add me to your list of superior beings 🤣
Easy to drill out a rim to fit a Schrader valve, come from the outside in (Presta = 6mm to Schrader = 8mm). I too dislike Presta.
Speak for yourself! Given my ineptitude I’d probably snap the rim.
Use a small round 8mm file.

Yep, but that's not the stumbling block, although I'm only ever one faffy tubeless setup away from doing my MTB's. But Shrader tubeless valves exist and are easy to get hold of.
On the road, for starters I'd have to drill the expensive carbon rims. I think a tapered grinding bit on a Dremel might be safer so that's not insurmountable. It's then the lack of products which is what annoys me. Why are Schwalbe pushing these click valves when they could just release a 60mm Schrader tubeless valve stem that everyone already has a pump for!

Mavic rims used to come with a little plastic shim that clipped into the hole.
I agree though, it's just fashion and inertia.
If Lachlan Morton went out and did a round the world record Schrader valves so he could re-seat them if necessary in a remote petrol station in northern Azerbaijan, then they'd suddenly be acceptable and people would question why they do still use those silly presta valves.
And another 9 months later (and a 27th thread) and i still haven't broken (or bent) a presta valve.why are Presta valves so rubbish? – Bike Forum – Singletrack World Magazine Forum
Aaaah, another one who can't tighten a thread or pull a press fit off in a straight line.
Must be 40 years now.
TBH if mechanical skills are not sufficient to stop the plunger bending then I’m not sure that same person should be taking a drill to a rim

I'm sure Stan's did them 15 y ago when I started with tubeless.

Plenty of brands still do, even fancy insert compatible high-flow ones.
All we need is some decent 60mm ones for modern road rims 😂
I had this happen in a minor crash, I guess it just caught a stick. Course, anything can happen in a crash but presta is definitely weaker than schrader. Stick this in your pipe "oh it's only if you're mechanically incompetent" people.
The broken valve is the least of your problems - that wheel looks toast!

Those Ultimate Schrader Valves - Miles Wide Industries valves look great - some nice innovations in there. This is the kind of $hit the industry should be doing, evolving good design with neat features. I love the 4mm Hex in the bottom so you can easily stop it spinning as you tighten it up.
Would also love to run dice caps again. That's not been a thing since my Schwinn or CW in the 80s.
Wasn't there some issue with metal caps seizing onto the valve stem?

Same 'issue' would apply to most expensive Shrader options. You know, the ones that come with an anodized cap with built in valve core remover.
Not that anyone ever need to remove a broken or clogged valve core, that never happens obviously .................
But yea, I had some Chinese TPMS valve caps (it had a succession of nails and my OPH is really bad at noticing a low tyre) seize onto the car which was a PITA. But dice valve caps are cool so I'd happily remember to put some anti seize on them 😂
Wasn't there some issue with metal caps seizing onto the valve stem?
Definitely happens on cars. Those aftermarket alloy caps can seize on, just stick with plastic. Seems less likely on a MTB (less road salt, more frequent removal) but still something to be wary of.
