All Together Faster

Quiver-killer? You want more than that. From the climbs to the crits, you’ll accept no compromises in aero performance, lightweight advantage, and flat-out, bunch sprint handling. CFD analysis shows the Sum Pro’s aero performance as equivalent to the all-aero Nitrogen and 9% faster than the Gallium Pro Disc. A lightweight layup is complemented by a minimalist candy clearcoat directly over the carbon. Design details like dropped seatstays and an indented seattube assure compliance in all the right places to keep you rooted in the saddle. An updated size range reflects our knowledge of rider fit, providing the best handling and positioning across all sizes.
