Well, you still have to do a bit of work, like downloading the app when it finally gets approved in iTunes’ app store or the Android Marketplace, which should be within two to four weeks. Then you need to input the ID code on your model year 2013 or newer fork or shock and follow some pretty simple onscreen instructions.
The app will use the ID code to determine what fork and/or shock you have and its compression and rebound settings and help you set it up with the proper sag.
To start, open the compression and rebound all the way, enter your body weight and it’ll tell you the recommended baseline psi setting. From there, you sit on the bike and move the sag sliders down, hop off and scan the stanchion or shock canister using your smartphone’s camera. Put the camera alongside the slider as shown above and it’ll scan the image while a cool red line Knight Riders up and down the stanchion. Once it spots the o-ring and compares it with the recommended position, it’ll adjust the recommended psi.
The ID code tells the app the model and what the compression and rebound tune is for that unit.
Instruction screens guide you through the process and you can save settings for your bikes and recheck it as often as you like.
Using just the video bit, there’s really no reason (that we can see) why the app can’t be expanded to simply let you input the model and/or serial number and simply use the visual gauge to determine sag. Fox’s rep kinda sort emphasized the “for now” part about it only working with 2013 and newer bits, so we’ll see.
