DESCRIPTION:This kit includes everything you need to replace the inner tubes in your tubeless ready rims and tyres with genuine Stans sealant--the original, and still the best tubeless tyre sealant. All Road and Gravel Bike Tubeless Kits include 118ml of sealant, 55mm brass valves, and Stans 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 23mm internal rim width would require the 25mm kit. We recommend going 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, Stans 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. Stans 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. Stans sealant lets you ride further, faster, and flat-free. All kits include 55mm brass valves
