This kit includes everything you need to replace the inner tubes in your tubeless ready rims and tires with genuine Stan’s sealant–the original, and still the best tubeless tire sealant.

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.

• 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 rim interior dry
• 200ml of sealant provides enough liquid to seal two 29” wheels with larger volume tires.
