The heavy-duty solution for fat bike adventures. This tube is specifically engineered to fill the massive volume of fat bike tires, providing a reliable and consistent air cushion for low-pressure riding. The 33mm Presta valve is kept intentionally short to reduce the risk of bending or snagging on trail debris, and the Removable Valve Core (RVC) offers essential flexibility for winter and off-road riding.
Key Features:
-
Fat Bike Optimized: Sized for massive 4.00 to 4.80-inch tires, ensuring the butyl rubber isn't overstretched, which maintains durability and puncture resistance even at very low PSI.
-
Removable Valve Core: Allows for the easy addition of liquid sealant to automatically plug thorns and small punctures—a crucial feature for off-road fat biking.
-
Low-Profile 33mm Valve: The shorter stem is perfect for wide fat bike rims, providing enough length for pump engagement while staying tucked away from rocks and brush.
-
Premium Butyl Construction: Built with high-grade rubber to ensure uniform wall thickness, which is vital for preventing "tube squirm" and air seepage during extreme cold-weather expeditions.
