Cannondale Topstone Carbon 2 GRX 2x 2025 - Gravel Bike
Carbon Frame
The Topstone is built on a lightweight carbon frame featuring Cannondale’s proportional response geometry delivering a fast and responsive ride. An extra long fork offset paired with a slack head angle is designed for lively steering while offering confidence on technical terrain. The frame also features internal cable routing throughout, combined with a concealed stem offering a tidy and integrated look.
Stash Port
All models now includes a StashPort downtube storage system, which can be easily accessed under the bottle cage, to allow you to carry all your essentials with you on shorter rides or offering more storage for bike packing trips.
Kingpin Suspension
The frame features Cannondale’s Kingpin gravel rear suspension. A thru axle pivot in the seat tube allows for the rear triangle and seatpost to flex vertically offering up to 30mm travel for additional compliance and will smooth out any bumps.
The Cannondale Topstone Carbon 2 GRX 2x is built for those who refuse to limit their riding to a single surface. Its lightweight carbon frame is enhanced by the Kingpin suspension system, which provides 30mm of rear travel without the weight and complexity of traditional suspension. This innovative design absorbs shocks and vibrations, ensuring a smoother ride on rugged paths while maintaining stiffness for efficient power transfer on the road.

Cannondale’s Proportional Response construction tailors the frame’s stiffness and compliance to each frame size, ensuring every rider experiences optimal handling and comfort. The integrated StashPort in the downtube allows you to carry essentials without additional bags, keeping the bike clean and efficient for long-distance adventures.
The Topstone's geometry strikes a balance between stability and agility, making it just as capable on fast descents as it is on technical climbs. Paired with a full carbon fork featuring internal routing and multiple mounting points for bottles or gear, it’s ready for bikepacking adventures or long gravel races.
Shimano’s top-tier mechanical gravel groupset, the GRX 820 2x12-speed, offers smooth and reliable shifting even under pressure. The wide gear range, featuring a 48/31 chainset and an 11-34 cassette, ensures you’re prepared for steep climbs and rapid descents alike. The GRX 820 hydraulic disc brakes deliver confident stopping power, with 160mm MT800 rotors ensuring precise control in all conditions.
The WTB KOM Team wheels and Riddler 700x45c tyres strike an ideal balance between low rolling resistance and off-road grip. Their tubeless-ready design reduces the risk of flats, letting you run lower pressures for improved traction and comfort.
Cannondale’s 2 carbon seatpost and the 2 ShortDrop flared bars contribute to a comfortable and controlled cockpit. The Cannondale Wheel Sensor syncs with the Cannondale App, providing hyper-accurate speed, distance, and route data, as well as service reminders, ensuring you stay on top of your bike's maintenance.
