The Schwalbe Pro One TT is a high-performance tubeless road bike tire designed for competitive cycling disciplines such as triathlon and time trials. This folding tire has a size of 28 x 1 inch (700 x 25C) and an ETRTO measurement of 25-622, optimized for modern 19C rims. It features the ADDIX Race compound, developed for maximum speed and grip on various road surfaces. The EvolutionLine construction technology, combined with LiteSkin and ClassicSkin layers, results in a durable, lightweight structure that reduces rolling resistance and improves aerodynamics. Tubeless Easy (TLE) compatibility allows for lower air pressures between 5.0 and 7.5 bar (70-110 PSI) for increased riding comfort and reduced puncture risk. The tire has a 127 EPI casing with an HS 493 profile, providing reliable cornering stability and straight-line performance. With a manufacturer-specified weight of 205 grams and a measured weight of 225 grams, this tire offers a balanced combination of performance features and durability. Each tire supports a maximum load of 70 kilograms. The black design with a beige sidewall (Skinwall) provides a classic aesthetic for unisex applications across various road cycling uses. This model is a successor to previous high-performance road bike tires from Schwalbe, incorporating refined materials and construction techniques developed through the brand's specialization in bicycle tire manufacturing. The tire design focuses on practical benefits for ambitious cyclists seeking measurable improvements in speed, handling, and reliability over extended use.
