ALL TOGETHER FASTER

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.

ELITE ENGINEERING

· Only slightly heavier than the SUM Pro, the SUM is our elite-level racer with a
performance-driven balance of aero and lightweight engineering.

RIDER-DESIGNED

· Ready to keep you in the saddle all day, the SUM features slender, dropped seat stays
for compliance, a refined sizing range for the perfect fit, and the latest-generation 3D headset system,
allowing you to raise the top bearing without losing any stiffness.

ALL THE BEST FEATURES

· Loaded with real-world, rider-oriented details like non-proprietary cockpit,
our updated 3D system for the widest fit window, easy adjustment - and maximum stiffness, and generous
tire clearance (30c).
