The 20 inch Fat Bike Inner Tube is a type of inner tube that is specifically designed for use with fat-tyre bikes. Fat-tyre bikes, also known as fat bikes, have tyres that are much wider than traditional bike tyres, typically measuring 4 inches or more in width. The wider tyres provide increased stability and traction on soft and uneven terrain, such as snow and sand.
This particular inner tube has a diameter of 20 inches and a width of 4 inches (ETRTO 100-406), making it suitable for use with fat-tyre bikes that have 20x4.00 tyres.
It comes with a schrader valve. The valve has a spring-loaded pin inside that can be depressed with a valve cap to let the air in or out.
The inner tube is made of a durable and puncture-resistant material, which can withstand the increased pressure and wear that is associated with the larger tyres of a fat bike. The inner tube is designed to be used with high-pressure, with a maximum pressure of 30 PSI.
