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 OutFront 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 Shimano 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 SmartSense-ready, for compatibility with the Cannondale SmartSense lighting and radar system, offering seamlessly integrated lighting and safety options (sold separately).

It can be argued that tires may be the most important (and most affordable) upgrades you can put on your bike. This rings true whether you are churning out miles on pavement, grinding gravel backroads, racing your local cyclocross course, or blasting dirt trails on your mountain bike. Getting the most out of your bike by matching quality compounds, impeccable construction, and cutting-edge tire tech is firmly rooted in the ethos of Specialized. Tires were the first product that Specialized offered and continues to be a fundamental focus of research and development for the brand.
Some things are just timeless. Like red brick is to buildings, steel is to bicycles. You may have noticed that finely constructed steel frames, crafted and welded by the best builders continue to be highly sought after for their unblemished combination of form and function.
When it comes to frame materials, nothing brings the WOW factor quite like Titanium. This magical metal combines the excellent ride feel of a steel frame, but without the weight penalty. Not to mention, just the beauty of a Titanium frame will keep your riding buddies drooling while they are struggling to hold your wheel.
