The Stan's No Tube Tape - 27 mm is designed to work with most tubeless-ready rims and wheels. A single layer in the bed of your rim is needed when inflating to 45 psi or less. Road Tubeless and like tires requiring more than 45 psi require a double wrap. This tape also creates a durable airtight seal over spoke holes so you'll never have to worry about flats and it can also help the bead slip into place more easily. It sticks where you want it, when you want it but won't leave a sticky residue. The Stan's No Tube Tape - 27 mm is ready for your next adventure. | Stan's No Tubes Rim Tape 27 mm
