All Mountain Bike Tubeless Kits include 200ml of sealant, 44mm brass valves, and Stan's Yellow Tape. Kits are offered in different tape widths to fit a variety of rims. If you're unsure whether your rims are tubeless-ready, look for graphics that mention it directly on the wheel or contact the manufacturer for details. Do not attempt to use a tubeless system on wheels that are not explicitly tubeless compatible. WHAT SIZE DO I NEED?: Stan's recommend tape that is 1-2mm wider than the internal width of your rim to account for the drop channel. For example, a rim featuring a 28mm internal rim width would require the 30mm kit. It is recommended to go with the wider option if your rims fall in between sizes. HOW DOES IT WORK: Their simple tubeless system begins with our Yellow Tape. Unlike some tapes that allow moisture to pass through them and into the rim cavity, creating a mess of glue and liquid that can corrode rims, Stan's Yellow Tape forms a non-permeable vapour barrier for airtight protection. Our tried-and-true tubeless valves offer simple, tool-free installation, with removable valve cores to allow for easier sealant refreshes. Stan's sealant stays liquid in your tyre, ready to seal a sudden puncture almost instantly, while letting you ride faster, and with more traction and control. Stan's sealant lets you ride further, faster, and flat-free. All kits include 44mm brass valves Everything you need to quickly and easily complete your conversion to tubeless Stan's Sealant seals punctures up to 6.5mm (1/4) quickly and offers long-lasting protection 44mm brass valves feature removable valve core for easy sealant refresh and fit most mountain rims Yellow Tape helps seal spoke holes airtight and does not allow liquid to pass, keeping the rim interior dry 200ml of sealant provides enough liquid to seal two 29inch wheels with larger volume tyres.
The Stans NoTubes Tubeless Kit - Mountain Bike (21mm Tape, 44mm Valve) is designed for mountain bikers looking to convert their tubeless-ready rims and tires to a tubeless setup. Its key benefit is providing a reliable, flat-free riding experience with improved traction and control. A potential caveat is ensuring your rims are explicitly tubeless-ready before attempting conversion. This kit includes essential components: Stan's Yellow Tape for airtight sealing, 44mm brass valves with removable cores, and 200ml of Stan's sealant, known for its puncture-sealing capabilities.

FAQs
How do I know if my rims are tubeless-ready?
Look for graphics on your rims that explicitly state 'Tubeless Ready' or 'TLR'. You can also check the manufacturer's specifications for your wheelset or contact them directly.
What size tape do I need?
Stan's recommends tape that is 1-2mm wider than the internal width of your rim. For example, a rim with a 28mm internal width would typically require 30mm tape. If your rim falls between sizes, choose the wider option.
How often should I add sealant?
It's recommended to refresh the sealant every 3-6 months. In very dry or hot climates, or with frequent punctures, you may need to do it more often. You can check the sealant's liquid state by removing the valve core.
Can I use this kit on non-tubeless-ready rims?
No, this kit is designed exclusively for rims that are explicitly tubeless-ready. Using it on non-tubeless rims will not create a reliable seal and could damage the rim.
How does the sealant work?
Stan's sealant contains micro-particles that are carried to puncture sites by escaping air. These particles, combined with the latex base, quickly form a seal over holes up to 6.5mm in diameter.
What is the benefit of running tubeless?
Tubeless setups allow you to run lower tire pressures for increased traction and comfort, reduce the risk of pinch flats, and often lead to a lighter overall wheel and tire combination.
Can I use this kit with tubeless-ready tires only?
Yes, it is essential to use tires that are specifically designed and marked as 'Tubeless Ready' (TLR) for a proper and safe tubeless setup.
Troubleshooting
Tire won't seat on the rim
Ensure the rim tape is applied smoothly and covers all spoke holes. Use a compressor or a tubeless-specific floor pump to rapidly inflate the tire. Check for any leaks around the valve or tape.
Slow leaks around the rim or tire bead
Spin and shake the wheel vigorously to help the sealant reach the leak. You may need to add more sealant. Ensure the rim tape is securely adhered to the rim.
Sealant not effectively plugging punctures
Ensure you have sufficient sealant in the tire. For larger punctures, you may need to use a tubeless plug kit in conjunction with the sealant. Refresh sealant if it has dried out.
Rim tape is peeling or not sticking
Remove the old tape, clean the rim thoroughly, and reapply new Yellow Tape, ensuring good adhesion. Avoid touching the adhesive side of the tape.

Not compatible with non-tubeless-ready wheels.
Setup, Compatibility & Care
Compatibility:
Ensure your rims are explicitly marked as tubeless-ready (TLR). Do not attempt to use this kit on non-tubeless-ready rims, as it will not seal properly and may damage the rim.
The 21mm tape is recommended for rims with an internal width of 19-20mm. For optimal performance, Stan's recommends tape that is 1-2mm wider than the internal rim width.
The 44mm brass valves fit most standard mountain bike rims.
Setup:
Clean Rims: Ensure your rim bed is clean and dry.
Apply Yellow Tape: Carefully apply Stan's Yellow Tape along the rim bed, ensuring it covers all spoke holes and extends up the rim wall. Overlap the tape by a few inches and press down firmly to create a good seal. Use a tool to puncture the tape at the valve hole.
Install Valve: Push the 44mm brass valve through the hole in the tape. Secure it with the included lockring.
Install Tire: Mount your tubeless-ready tire onto the rim. Ensure the tire bead seats properly.
Add Sealant: Remove the valve core (using a valve core tool) and inject approximately 2-4 ounces (60-120ml) of Stan's sealant through the valve stem. Reinstall the valve core.
Inflate: Inflate the tire to the recommended pressure for your tire and rim. You may need to use a compressor or a high-volume floor pump to seat the bead initially. Spin and shake the wheel to distribute the sealant.
Care:
Periodically check tire pressure before rides.
Refresh sealant every 3-6 months, or more often in dry climates, by removing the valve core and injecting fresh sealant.
Clean rim tape if it becomes excessively dirty or damaged.
