SKS Airspy SV

If you happen to’re obsessive about tire strain, the SKS Airspy SV is your dream widget. It is a pair of digital strain sensors that match over your valves and inform your cellphone or Garmin bike laptop your tire strain to inside 0.1 psi.

The widgets themselves use Bluetooth to transmit tire strain knowledge to an app – SKS MyBike – in your cellphone and ANT+ to ship it to a Garmin machine. The readings intently match these from a standalone gauge and numerous observe pumps and inflators, however I am a bit doubtful of 0.1 psi accuracy. Appears optimistic, and even when the Airspy achieves that, does anybody really want to know their tire strain that precisely? (We have now a characteristic on how to decide on the most effective bike tire strain in case you’re unsure what would give you the results you want.)

I discovered the Airspies to be usually straightforward and fast to make use of with my iPhone, however I did see them fail to connect with my Garmin Edge 1030 Plus now and again. And it took fairly a little bit of fiddling to determine how one can arrange the Garmin app. It’s not lined in nice element by the SKS directions or movies; they really want updating.

Putting in Airspies was very straightforward. You unscrew the small lock nuts on high of your valves, screw within the Airspy valves, push the electronics pod down over the valve and maintain all of it along with a knurled lock nut. Non-compulsory “anti-theft” mounts may be fitted between the Airspy and the closest spoke, however I actually did not get the purpose. They’ll decelerate a thief by a second or two, if that, and I discovered that in the event that they pulled the Airspy to the aspect in any respect, they stopped it from working.

You then set up the SKS/Mybike cellphone app in case you do not have already got it, set it to search for Airspies to pair with and voila! your cellphone exhibits your tire strain.

If that wasn’t thrilling sufficient, there is a Join IQ knowledge discipline so you may show the tire strain on a Garmin machine that helps Join IQ, which is just about all newer Garmins.

To attach the Airspies to your Garmin machine, you employ the Garmin Join cellphone app to inform the Airspy Join IQ app what to search for by feeding it the serial numbers of the Airspy gadgets from the Airspy app.

The method is barely talked about within the guide. For an Android cellphone observe these directions and for an iPhone use these.

Must you?

Okay, I hear you ask, that is very intelligent, however what do you truly do with that data? I believed the identical factor. In fact, it is about not stopping asking your self in case you may, however in case you ought to.

I’ve give you a number of use circumstances throughout my time with Airspies.

Use case 1: Is it actually a puncture? You recognize that nagging feeling that your rear tire is comfortable, however you are unsure at first if it is dropping air or in case you’re simply having a foul day? Airspy to the rescue with a warning that your tire strain has dropped.

You set this via the Garmin Join app in your cellphone the place you may set the goal strain to your tire and the utmost distinction from what you settle for. Set the strain to 70psi and the distinction to 5psi and you will get a loud alarm in your Garmin if the strain drops under 65psi, confirming that you simply’re not only a little bit of crap, you’ve got bought a puncture, and you must cease and repair it earlier than your costly carbon rim begins bouncing off the bottom.

These settings are fairly nicely buried in Garmin Join. To search out them, go to: Extra > Join IQ Retailer > Handle machine > My knowledge fields > SKS AIRSPY > Settings.

Use case 2: Do I have to inflate my tires? You recognize, nicely, you in all probability do, except you pumped them up, like, yesterday. However in case you’re unsure, you may examine them out of your cellphone or in the event that they’ve dropped too far, you will get an alert out of your Garmin machine as nicely. I do not use latex tubes, however for individuals who do, I can see the Airspy being a helpful reminder once they’ve misplaced strain.

Use Case 3: What’s the finest tire strain for my native gravel drive? With the Airspies in place, you can begin with a ridiculously excessive strain and step by step decrease it till you discover the strain that offers you the most effective compromise of grip, consolation, velocity and never getting pinch plates. That is the place the mad scientist prospects of Airspies come into play, though I am reminded of one thing we used to say when mountain bike suspension was getting tremendous refined and adjustable: with direct adjustment, you may be positive your settings are all the time mistaken.

Rivals

The one different comparable machine I do know of is the SRAM Quarq TyreWiz. TyreWiz has built-in LED lights to inform you in case your tire is under-inflated, so it may be used with out an app or bike laptop, but it surely solely works with tubes which have detachable cores, and a pair prices £253. It makes £110 for the Airspies seem like a discount.

There have additionally been Kickstarter initiatives that intention to do a lot the identical factor. BTPS didn’t attain its funding goal, and two current ones, PSIcle and Sensible iPump have reached the goal however are but to be delivered.

Who should purchase the SKS Airspy?

Principally mad scientists and tire obsessed. The Venn diagram for these classes in all probability contains time trialists and a few ultra-distance and gravel racers who need to stability the professionals and cons of various tire pressures.
