Cannondale Topstone CAAD 1 GRX 1X

Cannondale Topstone CAAD 1 GRX 1X

When the pavement ends, the fun keeps going. The Cannondale Topstone CAAD 1 GRX 1x is made for riders who don't want their route dictated by the surface ahead. Its high-quality SmartForm C1 aluminum frame combines a direct, agile ride feel with comfortable gravel geometry, while the lightweight full-carbon fork helps absorb vibrations on rough surfaces and delivers precise handling.

Shimano GRX 1x12 – simple shifting, endless possibilities

Less complexity, plenty of range: the mechanical Shimano GRX 1x12 drivetrain is an ideal match for the versatile character of the Topstone. A 40-tooth chainring paired with a wide-range 10–51 cassette provides plenty of gearing for steep gravel climbs while retaining the speed needed for fast, flat sections. With no front derailleur to worry about, the 1x setup is simple, robust and perfectly suited to gravel riding.
Shimano GRX 410 hydraulic disc brakes with 160 mm rotors front and rear provide powerful and predictable braking performance.

45 mm as standard – clearance for up to 52 mm

The Topstone comes equipped with 45 mm WTB Vulpine TCS Light gravel tires, but there's plenty of room to go bigger. The frame accommodates tires with a measured width of up to 52 mm while maintaining 4 mm of clearance on each side. This gives you the freedom to build an even more capable setup with additional grip, comfort and control for rough gravel and more demanding terrain.

Built for more than just gravel

Multiple mounting points on the frame and fork make the Topstone a great platform for longer tours and bikepacking adventures. Fenders, luggage and additional accessories can easily be added to suit your plans. Combined with tubeless-ready WTB ST i25 TCS 2.0 wheels, the result is a gravel bike that's equally at home on a quick after-work ride or a multi-day adventure.
