Using this Oxford Headset Spacer Tag Mount is a breeze. First, find one of the existing 10mm headset spacers on your bike's 1 1/8' steerer tube. Remove it and replace it with the tag mount. Make sure to use the supplied Torx security bolts and the Torx security tool to secure it properly. Once it's installed, place your Apple® AirTag™ in the mount. You can then track your bike's location on your iPhone or iPad. As for maintenance, since it's tested to IPX7 waterproofing standard, it can handle some water exposure. But try to avoid submerging it for long periods. If it gets dirty, just wipe it clean with a soft cloth. Remember, the Apple® AirTag™ is not included, so you'll need to get one separately.
