Cannondale Topstone CAAD 1 GRX 1x 2027 Wine Red

CANNONDALE TOPSTONE CAAD 1 GRX 1X 2027 WINE RED

The Topstone CAAD 1 GRX 1x 2027 pairs a SmartForm C1 aluminium frame with a carbon fork for rides that link tarmac, gravel tracks and changing terrain. Its single-chainring setup makes gear selection straightforward on long outings and mixed-surface routes.

Shimano GRX 12-speed gearing combines a 40-tooth chainring with a wide-range 10-51 cassette, providing low gears for climbs and loaded rides. WTB Vulpine 45 mm tyres and tubeless-ready WTB rims let you adapt the setup to your route. The Conceal C1 stem includes a computer mount, while frame and fork mounting points provide options for bottles, bags, racks and mudguards.

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.
