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 Road and Gravel Bike Tubeless Kits include 118ml of sealant, 55mm 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. Why convert to tubeless? Check out our Tubeless Tire Guide here.Features:- 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- 55mm brass valves feature removable valve core for easy sealant refresh and are compatible with road and gravel rims up to 45mm deep- Yellow Tape helps seal spoke holes airtight and does not allow liquid to pass, keeping rim interior dry- 118ml of sealant provides enough liquid to seal two tires- Core Remover Tool removes presta and schrader valve cores, allowing for easy sealant installation and replenishment.How does it work:- Our 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 vapor 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 tire, 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.
