Designed for versatility and reliability, Teravail Standard Presta Valve tubes deliver unmatched adaptability for cyclists seeking precision and durability across diverse terrains and riding styles. With an extensive range of sizes tailored to modern tire profiles—spanning ISO widths from 38mm to 50mm paired with a 27.5″ diameter—these tubes cater to everything from wide trail tires to narrower road setups (1.50-1.95″ labeled width). Their robust 0.9mm wall construction ensures long-lasting performance under demanding conditions while maintaining lightweight efficiency at just 83g per tube.

Key features include a threaded Presta valve design with a removable core, simplifying inflation adjustments and enabling seamless integration with both standard and custom valve extenders up to 40mm in length. This design not only enhances user convenience but also reduces pinch flats by accommodating thicker tires without compromising valve stability.

Packaged sustainably using recycled cardboard printed with eco-friendly soy ink, each tube arrives individually boxed within inner cartons of ten—ideal for retailers or bulk users managing inventory efficiently. A single master carton contains fifty tubes in total, offering cost-effective stock solutions for shops or multi-bike households.
