At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Topeak TubiHead Upgrade Kit is an upgrade for pretty much any pump using a 10mm hose. It cleverly removes the valve core, allows maximum airflow for inflation, then lets you reinstall the valve core without losing pressure. Pretty nifty if you have a tricky tubeless setup.

It's an age-old truism that air flows faster when nothing's in the way, or at least it would be if anyone thought it was worth pointing out in the first place. Your Presta valve's brass centre takes up pretty much all of the actual valve, hampering the properly rapid airflow you need during tubeless setup.

If you're really lucky your tyres may seat without removing the core, but for most people it needs outing. That means when you've seated the tyre sans valve core, you then need to pull the pump head off and get the core threaded in fully before all the air falls out again. This might not be an issue if your rim design and tyre bead co-operate to hold the bead in place, allowing a leisurely addition of core whilst the tyre is flat before reinflation.

But from time to time you strike a tubeless combo where as soon as the air escapes, the tyre bead moves away from the rim wall and all bets are off. That's the problem the Topeak TubiHead Upgrade Kit was made to solve. That, and having to re-inflate a tyre you just inflated, of course. Marginal gains, less work, etc.

This upgrade kit comprises a head, hose and a fitting to thread onto various (but not all) Topeak floorpumps – both chambered and standard. It's worth noting you'll really be wanting a charger-chamber pump for tubeless work, though.

The 108cm rubber hose is 10mm in diameter and is very similar to other pumps, which makes this kit of interest to more than just Topeak pump owners.

The Blackburn Chamber Tubeless Floor Pump connector is a different size to that of the Topeak, for example, but I had no issues swapping the head between hoses (via careful use of some lockjaw pliers and a cloth to protect the connector). As the internal and external hose diameters are the same, the fit on the Blackburn hose was just as tight and I can't see any issues with this mod.

Just blow

This Topeak works like any other Presta pump head – you just put it on and pump away – and there's a brass Schrader valve adapter which threads into a little keeper on the hose when not in use. For the party trick of unthreading a valve core you need at least 16mm of valve body visible, not including any locknuts. If you don't have 16mm free, Topeak suggests using one of its valve extenders. Of course to get the benefit of not having to lose all the air you'd have to leave the extender in place once seated.

The feel and fit of the head is premium. The body is clear to allow you to see what's going on inside, and the ends are machined metal. There's also a spring-loaded pressure release valve for easy head removal once inflated. This isn't a gimmick – with mucho psi inside there's a lot of pressure against the seal, which makes it harder to release and slide off the threaded sides of the valve body.

Twist of the knob

To use you first unthread the Presta locknut, then slide the head over the valve until it bottoms out. That puts the 'valve core knob' in contact with the core. A short twist aligns the indented sides of the core with the knob, so then you can unthread the core. There's a rubber ring that holds the core captive, letting it be drawn back clear of the valve body – you're then free to release the stored air into the tyre, hopefully seating in one go. You can always follow up with more air if needed.

Once you're happy, you then push the knob in and thread it back up, lightly finger-tight. You really don't need much effort here, and it's a very good idea to only ever do cores up finger-tight so you can remove them in the wild if needed.

With the core back in place you can add more air if needed, then equalise the pressure and remove the head, locking the core again. To assist removal straight out from the valve body there's a tab on the front of the head – you don't want to be removing it at an angle, lest you stress or fracture the alloy valve body.

No spare rubber

In practice it all works swimmingly. Every core I tried unthreaded and reinstalled just fine, and the thick rubber seal the valve body inserts into looks like it will last ages. There's no mention on Topeak's website that the rubber (or any other part) is available as a spare, however. The Topeak 2-year warranty isn't bad though.

Overall

The TubiHead Upgrade Kit is a well-executed solution to a fairly common problem. Tubeless rim and tyre designs are improving to the point that, with correct taping, a newly seated tyre often stays thus, but if yours don't – and your pump has a 10mm hose – the TubiHead should be high on your shopping list.

I got myself a set of reserve Fillmore valves that simply do away with the valve core.  Didn't really expect them to live up to the hype but so far I'm pleasantly surprised.  Prior to that I carried a couple of spare presta cores after once removing my pump after laborioiusly inflating a tubeless tire that had lost too much pressure only to see the core stuck to the pump head.  That is, during the second before it released and *plink* fell down a drain.  25 miles from home, pouring rain.  Good thing I was carrying a spare inner tube.

"it's a very good idea to only ever do cores up finger-tight so you can remove them in the wild if needed" - unless your on-bike pump is a Lezyne in which case do the valve core up tight or removal of the Lezyne hose will take the core with it. No need to ask me how I know.

I've never entered the world of pain which is tubeless, but I have wondered whether a judicious wrap of PTFE tape around the valve core threads would give enough resistance to prevent it unscrewing unwanted.

The trouble with Lezyne is that they attach my screwing onto the valve core and the two threads, one that attaches to the valve pipe and the thread that attaches to the pump are very similar so the friction is about the same. So it is 50/50 whether unscrewing the pump will unscrew from the valve core or the core will unscrew from the valve pipe.

I have their excellent track pump and also use their mini-pumps for roadside repairs (it's actually a couple of years since I've used it having gone tubeless 5 years ago). The advantage is that normally you get a good attachment and you don't risk bending the valve top which is delicate - most clip on pumps don't attach firmly enough to protect that without careful pumping technique (especially when you have to work hard to get pressure in a panic with 10 other riders glaring and timing you!). So swings and roundabouts.

The problem with my on-bike pumps is that they can pick up dirt and grime, even with the rubber cap, so are more prone to gripping the valve core.

I still prefer the system though. Whether PTFE would help or hinder, I'm not sure, as I thought the main point was you could get a better seal with less torque.

PTFE tape, for all it's friction-free prowess, adds a little stiction, a bit like nylok but not as aggressive. So just maybe it would make the pipe (valve stem) grip the core more than the pump attachment does. Or maybe try light thread-lock. Like I said, I'm not equipped to try it out.

Is there any reason (other than that they made it that way) that a pump could not screw on to the main stem of the valve, instead of onto the core? Am I missing something? I guess the attachment would have to be that much longer to swallow the entire valve core and reach the valve stem. But I keep seeing this about (only Lezyne?) pumps unscrewing the valve core, so it's clearly an issue.

I suspect that not all valves have an external thread and I'm not sure they are a standard thread size, especially on non-removable cored inner tubes. So I guess Lezyne had to go with the core thread.

I did wonder about the stiction and had considered thread lock but my usage of such is so rare now that I suspect it would end up being like my super-glue usage, a very expensive single application.

I'll give the PTFE a test run.

There is that little button to press on the Lezyne hose to relieve the pressure before unscrewing. Not sure if it actually helps matters or is just psychological, but I don't think I've had a core unscrew when I've remembered the little button press first...
