Equation
Summer starts here: Maximum value to max out those long days
Gallium CS Disc
All the engineering knowledge of our pro-level bikes, in a more accessible package. The Gallium CS will let you make your mark on those long training days, or jockeying for rank in the group.
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.
