Muc-Off Stealth Tubeless Valve Tag Holder Kit Description: The Muc-Off Stealth Tubeless Valve Tag Holder Kit discreetly carries an Apple AirTag GPS tracker within tubeless bicycle tires. Muc-Off Stealth Tag holders combine with tubeless valves to stash away AirTags where thieves won't easily find them: within the cavity of a tubeless tire filled with sealant. Three silicone pieces totally encase the tracker, holding it securely to tubeless valves and sparing the device from exposure to sealant while allowing signal communication for proper function. Features: Discreet mount for Apple AirTag trackers within tubeless bicycle tires Airtag is housed in a protective 3-part silicone mount and attaches to tubeless valves Rubber stem mount design allows sealant to flow freely Rubber valve mount design spares damage to AirTag during impact Intended for use with rear wheels Note: Does not include AirTag tracker
