Stan's NoTubes Rim Tape 21mm (Yellow) Unicycle this Bell Mountain Bike TireStans No Tubes have been producing tubeless solutions since 2000; Stan is now the first name in tubeless products. Please note that Stan's Yellow Rim Tape by itself is not a tubeless conversion. Traditional (Non BST) rims require the use of a Stans NoTubes rim strip to achieve a secure tubeless setup. Using only Yellow Rim Tape and Stans NoTubes sealant on a conventional rim can result in difficult inflation, and catastrophic "burping" issues.
