Checking tyre pressures is a part of the pre-ride ritual for each severe mountain biker. Listed below are the very best tyre stress gauges for the job.
For the reason that tyres in your bike are the one factor involved with the path, sustaining an optimum tyre stress ensures most grip, help and braking traction. Nonetheless, the tyres in your bike can leak air continuously, so that you’ll have to verify the stress earlier than each journey. You’ve got two choices – your thumb or a correctly calibrated stress gauge.

Slim and lightweight, the SKS Airchecker 2 is simple to hold on rides
Accuracy: 0.1psi | Weight: 53g | Score: 10/10
Causes to purchase: Correct to inside 0.1psi. Easy to suit on the valve with out dropping air. Small and lightweight.
Causes to keep away from: Solely measures as much as 155psi, so not appropriate for many shocks.
Reasonably than having a switchable system the SKS Airchecker 2 is a Duo headed design with Presta on one facet, and Schrader on the opposite. This gauge additionally rotates 180º, so you may connect the gauge after which rotate the physique so you may see the show. It’s much less cumbersome so you might simply carry it with you for those who’re experimenting with pressures for sure terrain or are simply bedding in a brand new set of tyres. The backlit show is simple to learn in low gentle and the mode buttons are fairly giant. On the highest is a bleed valve and it’ll show the present stress with out you needing to take away the gauge from the valve. It’s also possible to toggle between psi and Bar by urgent the On/Off button and switch the unit off by holding it for 3 seconds, though it does have a 30-second auto-off function.

Accu-Gage tyre stress gauge
Accuracy: 0.5psi | Weight: N/A | Score: 10/10
Causes to purchase: Correct. Straightforward to learn. By no means runs out of battery.
Causes to keep away from: Will get gummed up with sealant simply, so wants common cleansing.
Checking your tyre pressures earlier than each journey needs to be a ritual for each severe rider, however ultimately your digital gauge goes to expire of battery and depart you enjoying a irritating guessing recreation. Not so with the analogue Acc-Gauge, which by no means runs out of batteries as a result of it doesn’t want any – higher on your pockets and the surroundings. The big show reads out to inside 0.5psi, and a bleed button on the facet permits you to fine-tune the stress. Easy and efficient.

topeek_Tyre_pressure_gauge_on_green_background
Accuracy: 0.5psi | Weight: 68g | Score: 9/10
Causes to purchase: Reliable. Auto-off perform. Pushes on to valve simply.
Causes to keep away from: Solely reads in 0.5psi increments. Cumbersome. Straightforward to activate by mistake.
Because the title suggests, the Topeak Smartgauge D2 contains a rotating SmartHead that will help you have interaction hard-to-reach valves. It additionally has a small lever that you simply slide throughout to entry Presta and Schrader performance, that means you don’t have to drag the gauge aside and re-sequence any inside components.
The SmartGauge bleeps when it has a gradual studying (psi, bar or kg/cm2) and shows it for 25 seconds earlier than auto-shutdown kicks in to assist save the battery. The only CR2032 needs to be good for a number of thousand measurements however we discovered this gauge is vulnerable to turning on by chance in a toolbox. We’ve additionally misplaced the battery cowl on a number of samples and the SmartHead can turn out to be sticky, particularly when utilizing it with tubeless methods – a little bit of sealant can really leak into the top if you verify the tyre stress.

Topeak Shuttle Gauge
Accuracy: 0.1psi | Weight: 121g | Score: 7/10
Causes to purchase: Correct to inside 0.1psi. Easy to suit on the valve with out dropping air. Small and lightweight.
Causes to keep away from: Solely measures as much as 155psi, so not appropriate for many shocks.
The Topeak Shuttle is a digital stress gauge you can connect to an analogue monitor or mini pump. The donor pump then will get digital performance and likewise advantages from the Shuttle’s wider adjustment vary – it’s calibrated from 0 to 300psi. There are a few caveats – the pump wants to have the ability to inflate to that type of stress (most mountain bike pumps don’t) and it wants a thumb to connect to the small spigot on the physique of the Shuttle. It’s the standard of this thumb-lock that makes or breaks this machine as a result of some aren’t that tight and we discovered the Shuttle would typically wobble round. It has comparable good options Smartgauge D2, together with auto-off, a bleed valve, and so forth however the versatility does come at a worth.

Verify your tyre pressures earlier than each journey
How we take a look at
When evaluating stress gauges accuracy is essential, however in our expertise, most gauges are inside a 0.5psi tolerance, however to verify, we conduct a number of readings and work out a mean when checking tyre stress. We then take a look at performance and ease of use. For instance, if the gauge is convertible from Presta to Schrader is that fiddly to do? Does it have a swivel head to get into tight areas? Are you able to bleed air simply for those who overfill the tyre?
A stress gauge is one thing you’ll use earlier than each journey, so it additionally must be well-made and hard-wearing. Quite a lot of the plastic gauges flex extra if you connect them, and we’ve cracked screens; misplaced battery covers and dislodged buttons on some fashions.
We’ve additionally had extreme put on on the interior rubber components that create the seal on the valve stem. To check sturdiness, we frequently pull them aside a number of occasions through the testing interval. We additionally monitor battery life on the digital gauges, particularly since some activate a bit too simply when rolling round in a toolbox.
Are all stress gauges the identical?
When shopping for a stress gauge you’ve two selections – digital and analogue.
The digital gauges are barely costlier and since they’re battery-powered you’ll additionally pay extra in the long term as a result of you’ll have to substitute the battery. Most are additionally a plastic development, which is gentle, however it will probably really feel a bit flimsy within the hand.
Analogue gauges are usually not as frequent however the ones we’ve examined use steel components and are typically extra strong. They’re cheaper too and since there’s no battery, they don’t activate by chance in your toolbox.
Are digital gauges extra correct?
For measuring the stress in a mountain bike tyre, we’d say digital gauges are not any extra correct than analogue gauges, however they will measure stress in tenths of a PSI. It’s debatable whether or not you might want to be this exact however digital gauges even have a wider adjustment vary and may even measure pressures as much as 250psi making them appropriate for measuring shock and suspension fork pressures.
An analogue gauge is just as correct as the dimensions of the dial as a result of if it’s small it may be tougher to learn out the gradients. To get round this challenge a whole lot of low-pressure gauges designed for MTBs are solely rated to 35-40psi, that means it makes use of a much bigger scale, so that you may be extra exact.
Can they be transformed from Schrader to Presta if I run each sorts?
The bulk are convertible by flipping round some inside components, in the identical means as monitor or mini pump. Some gauges have a sensible head with a bit lever that you simply push a technique or one other to entry the 2 valve sorts. You additionally get two-headed gauges with a Presta on one facet and Schrader on the opposite.
If you happen to use one valve sort completely it might be value shopping for a set gauge that simply works on Presta or Schrader. In actual fact, most analogue gauges are this design.
What different options ought to I count on to see?
A bleed valve – helpful for lowering the stress for those who’ve overfilled the tyre. On the digital gauges, an auto-off perform saves the battery life. A swivel head permits you to manipulate the gauge in tight areas and likewise take readings with the valve on the prime or backside of the wheel. A carry case – this can be a precision instrument and must be protected.
