This 49N Presta valve inner tube is built for wide road, gravel, and adventure tires, with an internal fit spanning 700C wheels at 35–50mm tire widths. A 60mm valve stem clears deep-section rims without needing a valve extender, keeping setup simple on wider modern wheel and tire combinations.
Constructed from butyl rubber with a standard 0.9mm wall for reliable puncture resistance and everyday durability, it's a straightforward, dependable spare for gravel and adventure riders who don't want to gamble on an ultralight tube out on rough terrain.
