The Muc-Off Tubeless Tag Holder offers a discreet way to install a tracker inside your tubeless bicycle tire in conjunction with our Tubeless Valves, meaning you can track down your bike down in the event of theft and can locate it using the Find My iPhone App. Your tracker will be housed in a protective, 3-part silicone and rubber tubeless valve mount and supplied with our range of tubeless valve bases, so you can ensure an airtight seal is achieved against your rim when installing inside your tubeless tire. Please note: AirTag Tracker is not included with the mount, sold separately.
