Stan's Tubeless Kit - Montagne - 21mm

Upgrade your mountain biking experience with our comprehensive tubeless conversion kit, designed for tubeless-ready rims and tires. This all-in-one package includes 200ml of premium Stan’s sealant—recognized as the original and most effective tubeless tire sealant—along with 44mm brass valves featuring removable cores for easy sealant refills, and Stan’s Yellow Tape to ensure airtight sealing of spoke holes. Available in various tape widths to fit different rim sizes, this kit makes converting to tubeless quick and hassle-free. Stan’s Sealant effectively seals punctures up to 6.5mm (1/4) and provides durable protection, keeping your ride smooth and puncture-free. Ensure your wheels are tubeless compatible before installation—look for specific graphics or consult the manufacturer. Don’t attempt to use this system on non-tubeless rims. Everything you need to convert your mountain bike to tubeless is included, enabling a cleaner, lighter, and more reliable ride.
