Single Bakcou Heavy Duty Fat Tire Tube

• Military-grade butyl rubber stands up to punctures far better than a standard tube
• Variable wall thickness (3.5mm at the base tapering to 1.8mm at the rim) reinforces the high-wear zone while keeping weight in check
• Thicker than a standard fat-tire tube (1.8mm vs. the typical 1.7mm) for extra puncture resistance where it counts
• Extra-long Schrader valve makes one-way inflation and pressure checks easy, even through a thick rim
• Fits electric and traditional fat-tire bikes for broad compatibility from one tube

• Sizes available: 26"x4", 24"x4", 20"x4"
