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, 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 tyre.

How to fit

Fitting a tracker to Tubeless Tag Holder:

  1. Remove the Tubeless Tag Holder from the packaging then carefully remove the pink silicone top cap from the black rubber body, followed by the internal plug.
  2. Ensure the tracker is set up and connected to your iPhone app.
  3. Take your tubeless valve and remove the valve cap, locking ring and o-ring from the valve stem, then place the tubeless valve down into the hexagonal rubber slot in the black stem mount. Pull the valve through from the valve core side until the base of the valve butts up against the inner base of the mount. (Keep your o-ring and locking ring safe until you fit to your rim). 
  4. Position the internal plug over the hexagonal opening to block off the tracker storage compartment.
  5. Place the tracker into the top of the plug with the battery cover facing down towards the base of the stem mount. It’s best to push the tracker into place with both thumbs so that the sidewalls of the black rubber body come over the sides of the tracker.
  6. Then carefully fit the top silicone cover over the assembled tracker and storage compartment by flipping it upside down and stretching the cover over slowly until the entire compartment is covered. 
  7. Finally select the appropriate rubber grommet for your rim type and slide this over the valve stem until the base butts up against the bottom of the tracker mount.

Fitting into wheel:

  1. If using with an existing tubeless set up, deflate your tubeless tyre, pop your tyre off the bead and remove your tubeless valve. 
  2. Clean up the valve hole area on the inside of your rim with a clean microfibre cloth to remove any excess sealant before installing the Tubeless Tag Holder. (You can use our Glue & Sealant Remover for any stubborn sealant that needs to be cleaned off).
  3. Take your assembled Tubeless Tag Holder with the valve fitted and push the valve stem into the hole in the rim until it is all the way though. Then place the rubber o-ring onto the valve stem and slide it all the way down until it meets the rim.
  4. Screw the locking ring onto the valve stem and tighten down above the o-ring. This sandwiches between the locking ring and the rim. Push down on the top of the Tubeless Tag Holder inside the rim as you tighten the locking ring and tighten until the locking rick is hand tight and the rubber o-ring squashes out. This way you know you've created a good airtight seal. (TIP - don't overtighten as this can cause leaking. Finish by screwing on your preferred valve cap).
  5. Re fit your tyre, starting at the tracker stem, mount your tyre and ensure the bead is pushed passed the tracker stem base. 
  6. Use the valve core removal tool (integrated into spare alloy cap) to remove the core and fill with no puncture hassle tubeless sealant and inflate to your tyre manufacturers recommended PSI.  
  7. Job done, go ride! 

If using the Tubeless Tag Holder with a brand new tubeless set up and tyre, we would recommend inflating and snapping the tyre bead to the rim using your tubeless valve without the Tubeless Tag Holder fitted first. This is because the Tubeless Tag Holder may limit the larger quantity of airflow required for the initial tubeless set up. Then remove the valve and fit to the Tubeless Tag Holder using the fitting process and steps above.

NB: Periodically remove the tracker from the mount and dry off any excess tubeless sealant when replacing or topping up your sealant. 

You may need to replace the battery inside your tracker every 6 months to 1 year. 

We accept no responsibility or liability for any damage to the tracker as a result of using it with our tubeless valve mount system. 

Muc-Off Ltd and any of its group / connected companies are not liable for any loss of property or theft in relation to the use of this product. We recommend you use a high-quality lock whenever leaving your bike unattended or in your garage or home.


Will the system cause any damage to the AirTag?

Over the course of 6+ months of extensive real-world testing inside many different wheels we haven't experienced any damage to the AirTag as a result of using the Tubeless Tag Holder.  The built in sacrificial and compressive layer integrated into the system has been designed to ensure impacts are minimised to help protect your rim and the AirTag.

We do however recommend periodically removing your AirTag from the mount and dry off any excess tubeless sealant when replacing or topping up your sealant to ensure it is still working properly.

Is Tubeless Tag Holder waterproof?

No, it is not fully waterproof however we have designed the system to encapsulate the AirTag as best as possible and the AirTags being placed inside are IP67 standard meaning they are water resistant.

Will Tubeless Tag Holder work with other tracking devices?

Unfortunately not. We have designed Secure Tag holder to fit the AirTag specifically. We are looking into other devices though for both Bicycles and Motorcycles, which will work with Apple and other devices.

Can you run a tubeless insert with the tubeless tag holder?

No, unfortunately not.

Will the Tubeless Tag Holder work with my innertubes?

No, this is designed for bike wheels running a tubeless setup.

How much does it weigh?

The Stealth Tubeless Tag Holder weighs 7.5g without the AirTag & 18.7g with an AirTag.

Can I use this on either the front or back tyre?

We strongly recommend that you use this on your rear tyre.



Please note: The Stealth Tubeless Tag Holder is only compatible with tubeless setups using our All-New Tubeless Valves. Designed for use on rear wheel only.

Compatible tyre types:

  • MTB tyres (XC, Enduro Trail, Downhill, E-MTB).
  • Gravel Tyres (The narrowest recommended tyre size is 38c wide)
  • For road bikes with narrower tyres or incompatible wheel types, please use our Secure Tag Holder.

We recommend only using Stealth Tubeless Tag Holder with our No Puncture Hassle Tubeless sealant
