Stealth Tubeless Tag Holder & 44mm Valve Kit

The Muc-Off Tubeless Tag Holder offers a discreet way to install a tracker inside your tubeless bicycle rear tyre in conjunction with our Tubeless Valves, meaning you can track your bike in the event of theft and 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 array of tubeless valve bases, so you can ensure an airtight seal against your rim when installing it inside your tubeless tyre.

HOW TO USE

Assembling a tracker to the Tubeless Tag Holder: Remove the Tubeless Tag Holder from the packaging, then carefully peel the pink silicone top cap from the black rubber body, then the internal cap.
Ensure the tracker is set up and connected to your iPhone app.
Take your Tubeless valve and remove the valve cap, lock ring and o-ring from the valve stem, then insert the Tubeless valve into the black holder rubber hex housing for the stem. Pull the valve through from the valve body side until the base of the valve sits against the internal base of the holder. (Keep the o-ring and lock ring safe until you fit them to the rim). 
Fit the internal cap over the hex opening to close off the tracker storage chamber.
Insert the tracker into the top of the cap with the battery cover facing down, towards the stem holder base. It is best to push the tracker into position with both thumbs, so the side walls of the black rubber body overlap the sides of the tracker.
Then carefully fit the silicone top cover over the assembled tracker and storage chamber, turning it inside out and slowly stretching the cover until the entire chamber is covered. 
Finally, Select the appropriate rubber bung for your rim type and slide it onto the valve stem until the base sits against the bottom of the tracker holder.

Fitting into the wheel: If using with an existing Tubeless setup, deflate your Tubeless tyre, unseat the tyre bead and remove your Tubeless valve. 
Clean the valve hole area inside 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 cleaning off).
Take your assembled Tubeless Tag Holder with valve fitted and push the valve stem into the rim hole until it is fully through. Then place the rubber o-ring onto the valve stem and slide it all the way down until it meets the rim.
Screw the lock ring onto the valve stem and tighten it down over the o-ring. This sandwiches between the lock ring and the rim. Push down on the top of the Tubeless Tag Holder inside the rim whilst tightening the lock ring and tighten until the lock ring is hand tight and the rubber o-ring compresses. This way you know you have created a good airtight seal. (TIP – do not overtighten, this could cause leaks. Finish by screwing on your preferred valve cap).
Remount your tyre, starting at the tracker stem, mount your tyre and ensure the bead is pushed over the base of the tracker stem. 
Use the valve core removal tool (built into the spare alloy cap) to remove your valve core and fill with No Puncture Hassle Tubeless Tyre Sealant and inflate to your tyre manufacturer’s recommended PSI.  
Done, go ride! 
If using the Tubeless Tag Holder with a brand new Tubeless setup and tyre, we recommend inflating and seating the tyre on the rim using your Tubeless valve without the Tubeless Tag Holder fitted first. This is because the Tubeless Tag Holder may restrict the higher amount of airflow needed for initial Tubeless setup. Then remove the valve and fit it to the Tubeless Tag Holder using the assembly process and steps above.

NB: Periodically remove the tracker from the holder and wipe away 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 take no responsibility for any damage to the tracker arising from use with our Tubeless valve mounting system.
