Cannondale Topstone CAAD 1 GRX 1x - Platinum Bronze

Ready for everything

Our high-performance aluminium gravel bike is built on the long-standing tradition of CAAD and brings together everything we learned when making the best aluminium frames on the market. Ready to explore new horizons, discover remote roads, or get you to work faster.

A Topstone bike
It’s first and foremost a Topstone. Like the entire model range, this bike stands out for its perfect fit, confident handling and playful ride feel, all combined in a premium aluminium frame of the highest CAAD quality. Ready for rallies, races and long rides out – just like its carbon twin brother.

CAAD, by conviction
Cannondale Advanced Aluminium Design is a continuously developed aluminium tradition. Light, responsive, durable and easy to use: the Topstone CAAD embodies the quality we’ve refined for decades through the construction of world-class aluminium frames.

Ready for every day
Gravel racing on Saturday. Discovery ride on Sunday. City traffic on Monday. The Topstone CAAD offers generous tyre clearance, lots of mounting options and huge everyday usability – a gravel bike ready for everything.

CAAD
The manufacturing technology behind the light, robust and refined frame of the Topstone CAAD is Cannondale Advanced Aluminium Design. Precisely shaped and end-reinforced tubes, smoothed weld seams and clean lines deliver the high-quality ride feel and solid stiffness that CAAD is known for.

Full carbon up front
The full-carbon fork of the Topstone CAAD ensures light, precise steering, but it also features threaded bottle bosses for water bottles, panniers, gear and lights. It provides extra comfort where it’s needed and gives the gravel bike a precise, high-performance ride feel – on the road and off-road.

OutFront steering geometry
By combining a longer fork offset with a shallow steering angle, the OutFront steering geometry delivers confident stability and, at the same time, sharp handling. As a result, the front of the bike feels calm even at high speed, is responsive in tight spaces and also gives more confidence with smaller frame sizes.

Ready for suspension forks
The Topstone CAAD is designed for the fitment of a suspension fork, including our Lefty Oliver, so you can ride with even more off-road control on the same Topstone platform when needed. Same bike family. More performance up front.

Tyre clearance
Space for tyres with a measured width of up to 52 mm with 4 mm clearance on each side for more grip, comfort and control on a wide range of surfaces. The Lefty Oliver models are optimised for 700x47 mm tyres; in this case, tyre height is the key measurement for tyre clearance.

Endless mounting points
Bottles? Panniers? Mudguards? Racks? The Topstone CAAD has so many mounting points on the frame and fork that we stopped counting. Just fit everything – and a bit more.

Ready for a kickstand
A low-profile 18 mm kickstand mount with two threaded bolts makes the Topstone CAAD ready for everyday use in no time. Fit it when you need it. Leave it off when you can do without.

All sorted
The internal cable/rod routing and the Conceal stem create a tidy, integrated cockpit. No cable clutter, cleaner lines – and a gravel bike that looks as good as it rides.

Ready for a dynamo
All models except the Lefty and the EQ feature internal dynamo cable routing through the carbon fork, making the switch to integrated lighting easier. Developed for cyclists who want to make their gravel bike ready for longer days and starts in the dark.

BSA bottom bracket
The screwed 68 mm BSA bottom bracket with thread on the Topstone CAAD is simple, proven and easy to maintain. Less time spent on maintenance. More time for gravel riding.
