Global Critique
“The Cannondale Topstone Carbon 1 Lefty AXS is a superb evolution of a class-leading gravel bike — tweaks to the geometry, increased tyre clearance and practicalities like down tube storage add real comfort on rough terrain.”
“Cannondale's Kingpin rear suspension helps the bike hook up to dirt and rocks to prevent sliding out, while the Lefty Oliver fork makes big impacts feel less severe — together they make gravel less of a grind.”
“Straight out of the box, the Topstone Carbon Lefty is an exceptionally comfortable bike — vibration measurements show it comes remarkably close to highly optimised benchmark setups on the buzziest gravel surfaces.”
