The Full Feature Sheet

Universal Fit for 26" MTB/Road Bikes Our TPU inner tubes are specifically designed to fit 26x1.9-2.5" tires with Presta valves (45mm French length). These tubes seamlessly adapt to mountain bikes, making them an ideal solution for diverse biking needs.

Ultra-Lightweight Design Weighing only 63g per tube (70% lighter than traditional butyl rubber tubes), these TPU inner tubes significantly reduce rotational weight. Each pair reduces weight by 200g, enhancing acceleration, climbing efficiency, and overall speed for competitive riders.

Military-Grade Durability & Puncture Resistance Engineered to meet military-grade standards, our TPU walls measure 0.3mm thick, making them highly durable and puncture-resistant. Lab-tested to withstand up to 150 PSI and five times sharper impacts than standard tubes, these inner tubes ensure all-weather reliability.

Low Rolling Resistance = Pro-Level Speed With a thinner profile at 0.3mm compared to traditional butyl's 0.8mm, our TPU inner tubes minimize tire friction. Lab tests have proven they can boost speed by 1.5-2.2%, ideal for racers and endurance cyclists seeking marginal gains.
