The Muc-Off Tubeless Tag Holder offers a discreet way to install a tracker inside your rear tubeless bicycle tyre in conjunction with our All-New Tubeless Valves (will also work with our V1 presta valves), meaning you can track down your bike 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 tyre. Please note: AirTag Tracker & All-New Tubeless Valves are not included with the mount, sold separately. Only compatible with our All-New Tubeless Valves.
