Description

After my weekend activity setting up two wheelsets with tubeless tyres, one product I was glad to have was my BETO JetAir Tubeless Tyre Inflator. It’s seen enough use for me to value it as one of those items that makes my tubeless life that bit easier (even with my WTB ST i25 tubeless experience, seating the bead was not a problem). When it comes to getting air into the tyres, the Surge isn't overly laborious, with a 28mm tyre inflating to 60psi in 17 strokes, 80psi in 23 strokes, and 29 strokes if you are going up to 100psi. Value An air tank is a relatively inexpensive, use-first-time tool that enables you to easily and confidently run tubeless tyres on or off-road, thereby saving money over time in inner tubes, patch kits and many, many stops by the roadside in oft-poor winter weather to repair/replace inner tubes. Having struggled with difficult rims (I don't have a problem with Schwalbe tyres) I have found this to be a lifesaver! I thought about making a ghetto diy inflator however, I needed reliability and this inflator has worked every time, flawlessly.

The best thing about the Flash Charger is the Auto-select head – it fits both Presta and Schrader valves and clamps solidly to the valve stem. The Flash Charger produces a good blast of air and seated our test tyre first time. Due to the slightly smaller charging chamber the pressure in the tyre averaged around 30psi, which does mean you have to bleed off air rather than add strokes. There’s a release valve on the side but this only bleeds off air in the hose and main chamber. If you are after a tubeless inflator pump that draws attention wherever you take it, the Crank Brothers Klic Floor + Burst Tank is for you: it wouldn’t look out of place next to the flashiest superbike. The option to remove the chamber and use it as a ‘standard’ floor pump is nice, and if you can get used to the connection process it delivers good performance. The Topeak Tubibooster X is the most expensive standalone tubeless inflator in this test. It’s also rated to withstand the highest pressure, 124 bar to be exact. That’s over 1700 psi, a pressure which is impossible to reach with a floor pump. The unattainably high maximum pressure and heavy metal tank made us feel very confident charging the Tubibooster X to a ‘mere’ 160 psi for our tests. The inflator head is made of plastic and looks pretty basic. It works with both Presta and Schrader valves, providing you unscrew the end cap and flip the double-sided insert to work with its corresponding valve type. In our lab tests, the Tubibooster X scored with a great flow rate of 3.1 l/s and a one-shot pressure of 27 psi. It’s both easy to use and stable, and we were 100% confident pressurising it to 160 psi and beyond. When I set up tubeless tyres these days, they go up first time, and stay up. Mostly any cut will seal instantly with no intervention from me. Last time I recall even hearing a hiss was about 6 months ago, and that stopped within seconds. Maybe once a year there will be a 3mm+ cut that requires a rubber plug to seal - done on the roadside, no mess, no faff, not even removing the wheel. Some people swear by the ‘inflate with inner tube, leave for a period of time and then remove the tube’ approach. This has its merits but its the ‘leave for a period of time’ part which can sometimes frustrate, especially if I’m particularly enthusiastic to get riding.

There’s nothing particularly flashy about this tubeless inflator pump. It’s well-built, and even the plastic parts feel robust. The wide handle is comfortable to use, and the stroke is smooth and pretty well dampened. The large, easy-to-read gauge proved to be accurate in our tests, however, it does need a little while to settle before you can take a reading. The Presta + Schrader Smarthead is a great feature, allowing you to use the pump on both types of valves without having any faff. We also liked the twist-to-release lever, which matches the overall robust feel of the pump. The Topeak JoeBlow Booster performed averagely in our lab, recording a peak flow of 2.8 l/s in our test scenario and a one-shot pressure of 24 psi. While these numbers weren’t outstanding, we were impressed by the JoeBlow’s reliability, bomb-proof build and useful features. Tubeless tire inflators have a high-pressure cylinder that is charged with air from either an integrated floor pump or a separate pump, normally to a pressure of 140-200 psi depending on the model. The inflator is then connected to the tire and using a lever, the air is rapidly released, the rush of air forces the bead of the tire onto the rim and seals it tight. No swearing, no sweating, just an overwhelming sense of accomplishment: this is how you should feel after following our tubeless setup guide. There are a host of models for every budget, but the first decision boils down to the following two choices: “I already own a good floor pump”

If you've ever wondered how we got into mountain biking and how the MuddyMoles started, well wonder no more. There are 9 comments on ‘BETO JetAir Tubeless Tyre Tank and Inflator’ This gauge allows you to effortlessly switch between presta and schrader valves in seconds, allowing you to easily measure your tyre pressure no matter what bike it’s on, be it mountain bike or a road bike. The accuracy is great and the display lights up brightly which makes it easy to read. It also includes an air release button, which coupled with this device's accuracy, is useful in letting you know how much pressure you’ve let out in real time, ensuring you don’t let too much out at once.

How we tested the best floor pumps and tubeless tyre inflators

Mountain Biking product shot in the studio 2. Bontrager Dual Charger floor pump Best budget floor pump for mountain bikes The BETO JetAir splits the difference between cost and portability that a combined pump and charge tank provides, at the expense of a minor amount of faff in comparison. This is a question that likely would have had a very different answer 20 years ago; but as tyres and rims have got wider and common wisdom on rolling resistance and aerodynamics has involved, so has the preference on what PSI to run on road bike tyres. In the old days it was thought that tyres simply needed to be as narrow and as hard as possible, but all the evidence suggests that's simply not the case. We're talking about speed and rolling resistance here, but another great benefit of running wider tyres at lower pressures is greater comfort. Performance wise, this pump is really impressive for the money. Maxing out at just under 160 which took 49 strokes during testing on a set of road tyres, no wrestling was needed to achieve this: it simply reached a point in the downstroke and that was it. This pump also features an easy-to-read pressure gauge that is situated half way up the barrel, which gives you both psi and bar, which is useful.

He was heavily involved in the mountain bike boom of the late 1980s as a racer, team manager and race promoter, and that led to writing for Mountain Biking UK magazine shortly after its inception. He got the gig by phoning up the editor and telling him the magazine was rubbish and he could do better. Rather than telling him to get lost, MBUK editor Tym Manley called John’s bluff and the rest is history. Solid build quality is essential for surviving the rigours of a home mechanic’s garage, boot and life. Weight is less of an issue here… In fact, a heavy base keeps the pump stable A dual head that works with both Presta and Schrader valves is important The testing process so all the folks you meet use tubless? No? That my point. I get that folks into the kit or the advantages for them make more sense. At the moment inner tubes are a cheaper and simpler solution unless your using a very favourable comparison. Birzman have nailed the aesthetics of their Pump Up tubeless inflator. The sleek metal body, plastic end caps and flashy inflator head all look amazing. We are also fans of the long hose, which is neatly stored when not in use. In fact, there isn’t much to dislike about the Pump Up inflator, until you try to inflate a tire with it…

QUESTIONS & ANSWERS

There's some debate about where the pressure gauge should be. Some manufacturers put it at the top of the barrel, which makes it easier to read, others put it at the bottom because it's less likely to get damaged there if the pump falls over. If you go for pump with a high gauge, make sure it has some sort of protection against falls. It has a decent length 105cm hose and comes with a top-mounted gauge, which is close to the user but the numbers are quite small, so are not that easy to read. The handle is not the most comfortable either, when it flexes for the final few charging strokes, and there’s also a slightly cheap metallic feel to the pumping action. Mr ANDERSON This is a fantastic device, and essential for seating difficult 700c / 28 inch road tyres. I have never had any problems seating tubeless tyres on my 26" Mavic mountain bike rims however, I have recently been struggling to Schwalbe G-One tubeless easy tyres onto Alex Draw 1.9P tubeless rims.
