Cannondale Topstone CAAD 3 CUES Flat Bar

Urban versatility and gravel spirit

The Cannondale Topstone CAAD 3 CUES Flat Bar combines the versatility of the Topstone CAAD platform with a configuration designed for riders who prefer a flat handlebar. Its more upright riding position and direct steering response make it suitable for everyday rides, commuting, cycle paths and gravel adventures.

Aluminium frame and carbon fork

The SmartForm C1 Alloy frame features custom-shaped, butted tubes, smooth welds and clean lines. The full-carbon fork helps keep weight down and provides precise handling, while also incorporating mounting points for bottle cages, bags, accessories and mudguards.

Shimano CUES drivetrain

The 10-speed Shimano CUES drivetrain features a 40-tooth chainring and an 11–48 cassette. This setup is designed to deliver precise, reliable shifting, with a gear range suited to a variety of riding conditions.

Wheels and tyres for mixed terrain

The 700c GXD 1.0 wheels are paired with WTB Riddler Comp 700 × 45c tyres, which are tubeless-ready. The frame provides clearance for tyres up to 52 mm wide, with 4 mm of clearance on each side, helping promote grip, comfort and control across different surfaces.

Practical and ready to customise

The Topstone CAAD features numerous mounting points on the frame and fork for bottle cages, bags, racks, mudguards and lights. It is also compatible with a kickstand and dynamo-powered lighting systems. Internal cable routing, a threaded BSA bottom bracket and a UDH derailleur hanger complete a design intended to simplify maintenance and customisation.

Compatibility with suspension forks, including the Lefty Oliver, further expands the platform's configuration options.

The ideal choice for riders looking for a practical, versatile bike that can handle everyday journeys and gravel rides, combining a comfortable riding position with a functional setup.
