Own the season: the Sum will get you ahead on the climbs, keep you there on the flats, and power you through the sprints. Featuring the same optimal balance of aero and weight as the Sum Pro, the Sum is your all-around KOM-hunter.
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.

From the classics to the centuries, the Sum is engineered to keep you in churning out the watts no matter what the course - or the competition - throws at you
