The Cannondale Topstone Carbon LTD Di2 2025 delivers the same smooth shifts and rides as the top-end rigid fork model in the lineup. Equipped with Shimano's GRX825 Di2 group, known for its flawless electronic precision, and paired with Reserve's carbon 40|44 GR rims and DT-Swiss 270 hubs, this bike brings speed and versatility to the gravel game.

Kingpin is a lightweight, rear suspension system that allows for longer rides. It requires minimal maintenance and is designed for simplicity, providing the Topstone frame with legitimate rear-wheel travel while maintaining stiffness for sprints. Kingpin results in a smoother ride, improved traction for a more powerful push, and increased flexibility to handle rough terrain. It's unobtrusive, but its presence will greatly enhance your riding experience.

The newly-added StashPort storage system, located in the downtube, is thoughtfully integrated and easily accessible. With the complementary StashBag, you can conveniently bring your necessary supplies on any excursion, with the reassurance that they will be securely stored. In addition, the frame's numerous mounting options invite you to explore and carry even more gear.

Optimize your ride with Proportional Response Construction on the Topstone, where the carbon layup and geometry are tailored to each frame size. This includes KingPin suspension for a ride that is truly customized to your needs and body measurements.
