Topstone Carbon 4 Bike

What Our Gearhead® Experts Are Saying:

"This bike handles chunky roads way better than a hardtail gravel frame. The Kingpin flex system in the rear triangle makes it feel like there’s mild rear travel—without any moving parts. I’ve set mine up tubeless with 45mm tires, and it’s become my go-to for gravel centuries and lightweight bikepacking."

The Cannondale Topstone Carbon 4 Bike stands at the intersection of speed and capability, featuring an ultralight carbon frame and Cannondale’s proprietary Kingpin suspension system. This unique rear-stay design allows controlled vertical compliance, increasing traction and comfort across chunky gravel and broken backroads—without the weight or complexity of rear shocks.

Shimano GRX components anchor the drivetrain, optimized specifically for gravel with a clutch rear derailleur, secure chain retention, and smooth shifting across varied terrain. The frame accommodates wide tires for aggressive grip or comfort-oriented builds, and its internal routing, flat-mount disc brakes, and 12mm thru-axles deliver modern performance with clean aesthetics.

Mounts for racks and fenders extend the Topstone’s capabilities to bikepacking and commuter duty, while the endurance-focused geometry keeps riders stable and efficient on long-haul rides. Whether you’re training for a gravel event or plotting your next multi-day route, the Topstone Carbon 4 offers a tuned, fast, and forgiving ride across every surface.
