Product Description


The Cannondale Topstone Carbon Ultegra RX is a performance gravel bike with a lightweight carbon frame that can take on any challenge on or off the road. The Topstone is Cannondale’s first ever gravel bike. It is also the first gravel bike on the market to feature a rear suspension. While the Topstone aims to provide a compliant feel with that suspension, it is also incredibly fast thanks to the stiff and lightweight carbon frame as well as responsive pedaling input and power transfer. This version of the Cannondale Topstone combines outstanding performance with affordability for the adventurous rider.

The main talking point on the Cannondale Topstone is the innovative rear suspension. The 30mm KingPin suspension is a simple system with thru-axle pivot that connects the seatstays to one another. The pivot sits between a pair of bumpers in the seattube. Overall, this system allows for a total of 30mm of travel. More compliance is added to your ride with the help of a dropper post that creates 27.2mm of travel. Despite all this added shock absorption, the feel of this suspension is subtle and will not get in the way of fast riding. It is simply there to give you the confidence to tackle obstacles at high speeds without dealing with annoying vibrations.

A unique geometry is also implemented in the Cannondale Topstone to further set it apart as a step forward in gravel technology. Cannondale calls this Endurance Fit which keeps you low enough to feel like you are on a fast road bike but not without the aggression that could compromise your comfort and endurance feel. It also contains an OutFront Steering fork that places the front wheel further in front. That extra-long wheelbase gives riders extra stability through endurance terrain and around tight corners. With this diverse geometry, you will feel capable off the road and comfortable on it.

The incredibly stable Cannondale Topstone features short 415mm chainstays and clearance for tires from 700c to 650b. With these options, you will be ready to conquer anything with no compromises. It is also convenient for customization with a muti-position bottle cage that can be moved depending on where you like to keep your hydration. Fender mounts are available as well so you can protect your tires from the elements. Disc brakes are the standard on this bike for powerful and modulated stopping and heat dissipation in all conditions. This version of the Topstone is equipped with a Shimano Ultegra RX groupset for reliable mechanical all-road shifting at a great price. The Cannondale Topstone Carbon Ultegra RX Disc can do it all for a solid price.
