All Together Faster

Decisions, decisions… made easy. With a bike that gives you flat-out advantage on the climbs, the sprints and the straightaways, the only decision you’ll need to make is how nice you want to be to the other guys. A rider-oriented design approach ensures a frame that is both rooted and responsive, with a ride experience most aero frames can’t match. With a layup engineered to maximise aerodynamics while keeping weight low, the design process for the Sum allowed us to strip away all unnecessary weight within the new aero profile tube shapes – all while maintaining maximum power transfer.
