The weight savings result from a combination of new lamination and manufacturing techniques. The University Politecnico Milano utilized 3D-printed molds to recreate and optimize frontal aerodynamics and lateral stiffness in hard-to-control areas.
This innovation has produced a frame that improves upon something already capable of winning the Tour de France. More races today are won by riders who gain an advantage on the climbs and then extend it during descents. The Tour de France's Stage 4 and Giro di Lombardia are recent examples from 2024.
The thinner fork and headset not only contribute to overall weight savings but are also designed to provide riders with enhanced control and instantaneous reactivity during the most technical descents. To maintain internal cable routing, the fork section features a D shape. Additionally, the two bearings have different dimensions, with the top one being 1"1/8 and the bottom one 1"1/4, as seen in the V4Rs.
