Equation
Summer starts here: Maximum value to max out those long days
Sum
Own the season: the Sum will get you ahead on the climbs, keep you there on the flats, and power you through the sprints.
Sum Pro
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.
