While this is an old technology for cars and trucks, for bicycles it is relatively new and did not even have an internationally accepted design standard (ISO or ETRTO) until recent years. By eliminating the inner tube it is possible to lower the weight and create a softer, more comfortable, more efficient, lower rolling resistance tyre system by running lower tyre pressure. Challenge started introducing Vulcanized Tubeless Ready (VTR) tyres in recent years because the ISO and ETRTO standards for proper VTR tire and rim fit have finally been completed. These standards ensure your safety and your ability to fit and service the tyres with hand tools. Buy Challenge Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
