Cannondale Topstone Carbon 4 Bike Meet the next generation of gravel bikes The Cannondale Topstone Carbon is more than your average gravel bike. It’s Cannondale’s no-holds-barred, no-limits, any-road, any-gravel bike. With a revolutionary suspension design, lightweight construction, and confidence-inspiring geometry, the Topstone Carbon redefines what a gravel bike can do. The Topstone Carbon features the Kingpin rear suspension design, a series of flex zones and bushings that offer up to 30mm of rear travel, for increased traction, and comfort without added weight or complexity. The Out Front steering geometry blends off-road stability with lively steering agility, while tire clearance up to 700x45c and dropper post compatibility make the Topstone Carbon supremely capable and confident on any surface. This Topstone Carbon 4 Bike features the gravel-specific GRX 400-series drivetrain. This 10-speed groupset is designed and optimized for the unique demands of riding a drop-bar bike off-pavement, including a clutch-equipped rear derailleur, an ultra-wide 2x gear range, and a brake lever design that offers more control on the gnarly stuff. The Topstone Carbon 3 L rolls on Formula hubs with WTB ST i23 TCS rims and WTB Riddler Comp 700x45c tires for confidence-inspiring grip and handling on any surface. This Topstone is also Smart Sense-ready, for compatibility with the Cannondale Smart Sense lighting and radar system, offering seamlessly integrated lighting and safety options (sold separately).
