The Muc-Off Secure Tag Holder 2.0 offers a secure way to install an AirTag tracker* to your bicycle frame using the bottle cage mounting holes, so you can track down your bike in the event of theft, and can locate it using the Find My iPhone App. Your AirTag tracker will be housed in a machined, aircraft-grade 6061 aluminium body, that’s supplied with 2 sets of T25 security Torx bolts and a security key for an extra level of protection against theft. Secure Tag Holder 2.0 now features slotted bottle cage mounts which are designed to work with most existing standard bottle cage mounts (64mm spacing) and offer more adjustability.
