PRODUCT DESCRIPTION
Cannondale Topstone Carbon 3 GRX – 1x
Simplicity, comfort and unlimited adventure.
The Topstone Carbon 3 GRX – 1x is the perfect gravel bike for those looking for a sturdy, lightweight, and hassle-free bike. The full carbon frame with Kingpin technology provides up to 30 mm of controlled flex to absorb bumps, maintaining traction and control even on the roughest trails.
Thanks to the Shimano GRX 1×12 drivetrain with a 10–51 cassette, it offers wide gearing for tackling steep climbs and fast flats with maximum ease. Multiple mounts for water bottles and bags, along with the StashPort storage compartment with included bag, make this bike ready for any journey, from fast gravel riding to bikepacking.
With tubeless-ready WTB ST i25 wheels paired with generous WTB Riddler 700x45c tires, it's stable, smooth, and confident on any terrain. Plus, an integrated wheel sensor lets you track speed, mileage and service via the Cannondale App.
