Cannondale Topstone Carbon 4 CUES Bike

Carbon performance, gravel-ready from the start.

The Topstone Carbon 4 CUES 1x delivers everything that makes the Topstone platform great — KingPin rear suspension, OutFront geometry, Proportional Response carbon construction, StashPort downtube storage, and 27.2mm dropper post compatibility — at an accessible entry point. Shimano's CUES U6000 1x11-speed group brings durable, wide-range LinkGlide shifting and reliable hydraulic disc braking in a package built for the long haul. WTB ST i25 tubeless-ready rims, Shimano Centerlock hubs, and WTB Riddler 700x45c tubeless-ready tires roll confidently across gravel, backroads, and whatever else you point this thing at.
