Climbing performance isn't just about weight. Developed using Reserve's Turbulent Aero technology, the 34|37 TA combines a lightweight construction with a mixed-depth rim profile that maximizes aerodynamic efficiency on every ascent. Now 30 grams lighter per rim and 4 watts faster in the wind tunnel, it's built to help riders reach the summit faster. Reinforced spoke holes enhance durability and stiffness, while practical features like external nipples, standard spokes, a semi-hooked rim profile, and no rider weight limit make ownership simple. Backed by a lifetime warranty and no-fault crash replacement.
