Cannondale Topstone CAAD 1 GRX 2x 2027 Platinum Bronze

CANNONDALE TOPSTONE CAAD 1 GRX 2X 2027 PLATINUM BRONZE

The Topstone CAAD 1 GRX 2x 2027 is built for rides that combine quiet roads, gravel tracks and longer journeys. Its SmartForm C1 aluminium frame and carbon fork provide a versatile platform for riding light or setting up a multi-day route.

The Shimano GRX 2x12 drivetrain pairs 46/30 chainrings with an 11-36 cassette. The double chainring gives you more ways to fine-tune cadence between fast sections and climbs. GRX hydraulic brakes, WTB Vulpine 45 mm tyres and tubeless-ready WTB rims complete the setup. Luggage mounting points and the Conceal C1 stem with an included computer mount help you prepare for each ride.

OutFront steering geometry combines a 55 mm fork offset with a relaxed head angle for stability on gravel and responsive handling. The frame uses a UDH hanger, a threaded 68 mm BSA bottom bracket and a 27.2 mm seatpost. Multiple mounting points make it easy to adapt the bike for daily journeys, gravel rides and trips with luggage. Tyre clearance accommodates a measured width of up to 52 mm, with 4 mm of clearance on each side.
