The Evoke has computer optimized cross sectional profiles and shapes throughout, for pedaling stiffness with ride compliance. The semi-sloping top tube uses less material and therefore creates less weight, but lowers the center of gravity and improves the rigidity. The fork and frame stays are ride tuned to create the perfect balance of agility and stability. Available in a full seven size range from 47-62cm. Modular Monocoque Carbon Frame All frames have Lifetime and No-Fault Warranties
