All together faster. The Sum gives you an advantage on the climbs, in the sprints and on the flat, with a rider-focused design that feels both planted and responsive.
Elite Level Layup carbon is engineered to maximise aerodynamics while keeping weight low, and the Topological Compliance System gives it a smoother ride than most aero frames can match.
