Both bikes share a top-of-the-range frame and saddle, but differ in their groupset and weight. The Ultimate, equipped with the SRAM RED eTap AXS system, is lighter than the Pro, which uses the Shimano Ultegra Di2 system. As for the wheelsets, the Zipp 858 NSW offers maximum aerodynamic efficiency and is lighter, ideal for time trials and triathlons. The Zipp 404 Firecrest, on the other hand, offers a good balance between aerodynamics and weight, making it more versatile and suitable for different types of terrain.
Are you going for the highest possible, do you want to leave nothing to chance and do you want the best of the best? Then the Ultimate is the perfect bike for you! Do you want to be on the front row for a dime? Then the Pro is a good bike for you!
