Cannondale Topstone Carbon 2 AXS Smart Sense Bike Always ready The Topstone Carbon 2 AXS Smart Sense is Cannondale's do-everything gravel bike - just as comfortable chasing a fast gravel group ride as it is several days deep into a bikepacking route. King Pin rear suspension smooths out the rough without adding complexity, delivering up to 30mm of bump-softening travel through a thru-axle pivot in the seat tube. Out Front geometry keeps the handling light and lively, Proportional Response carbon construction tunes the ride by frame size, and Stash Port downtube storage means you can bring what you need without stuffing a pack. Smart Sense Gen 2 integrated lights and Garmin radar run from a single concealed downtube battery, keeping you visible and aware whenever the ride stretches past sunset.
