Cannondale Topstone 1 GRX 2X
Description
Always Game
Our highly capable aluminum gravel bike. Built for chasing horizons, exploring routes less travelled or accelerating your commute.
Smoother Ride, Swifter Pace
With room for wide 52mm tires, a comfort-focused frame design, and OutFront Steering, Topstone CAAD gives riders more confidence when the surface turns loose, broken, or chattery. Bigger tires add grip and comfort, while the geometry helps the bike hold its line without feeling dull. Add Lefty Oliver on selected models, and the front end gains even more control.
Carry More Than Speed
Designed to move and built to carry, Topstone CAAD gives riders mounts across the frame and fork for bottles, bags, fenders, racks, lights, and the good ideas that need hardware. Flush top tube bosses leave the frame clean when the gear comes off, while rack, fender, kickstand, and dynamo compatibility open up more ways to ride.
Tested For Real Use
Topstone CAAD is made for riders who actually use their bikes. Loaded rides, wet commutes, dusty backroads, repeat. We test it hard, refine it, and back it with a lifetime warranty because confidence should come standard. Light, tough, and ready for repeat days on road, dirt, and everything between.
Easy To Live With
Topstone CAAD is built around practical standards that make ownership simpler. A BSA threaded bottom bracket, UDH, standard thru-axles, 27.2mm seatpost, standard steerer compatibility, and clean internal routing all make the bike easier to service, adjust, and set up your way. Less hassle, more ride time.
Model Description
The premium 2x drop-bar build for riders who want the Topstone CAAD feel with a wider gear range and tighter cadence control. Topstone CAAD 1 GRX 2x pairs a premium aluminum frame and carbon fork with Shimano GRX 610 2x12 shifting, many smart mounts, WTB i25 wheels with WTB Vulpine 45 tires, and a clean Conceal cockpit.

Designed with purpose
- Lefty Suspension® For over 20 years, Lefty has been smoother, stiffer, and more precise than anything else out there. When it comes to suspension performance, Lefty stands alone.
- SmartSense™ SmartSense is Cannondale’s unique, discrete, and fully-integrated ecosystem of on-bike lights, rear-facing radar, sensors, and connected smartphone app. Designed to enhance visibility and awareness for you and other road-users alike, it’s the clever companion that inspires you to ride more, and with more confidence.
- HeadShok™ Urban front suspension that’s head and shoulders above the rest. HeadShok delivers more comfort and control, with less weight, less wear, and less maintenance than conventional forks.
- Delta Steerer Delta is an innovative steerer tube design that’s exclusive to Cannondale. The unique v-shape enables cables to be routed internally while minimizing the headtube’s frontal area, resulting in sleeker looks and less aero drag than other internally-routed road and gravel bikes.
- KingPin™ With lightweight, bump-taming suspension built right into the frame, KingPin turns rough terrain into smooth sailing. It’s the extra boost you need to crush rugged paths, ride faster, and go further – no second thoughts needed!
