CannondaleTopstone Alloy

01
Origin
The Topstone Alloy is the accessible entry into Cannondale's gravel world — the aluminium counterpart to the carbon, KingPin-equipped Topstone. It trades the rear-flex suspension for an honest, tough SmartForm alloy frame with dropped seatstays for a little built-in give, big 45 mm tyre clearance, and a generous array of mounts for racks, bags and bottles. Reviewers consistently call it a strong-value gravel and fire-road bike that's still happy on light singletrack.
