The Cannondale Topstone 1 Gravel Bike is light and lively, smooth yet snappy. It has a SmartFormC2 Alloy construction showcases Cannondale's decades of expertise in aluminum craftsmanship. A full carbon fork with tapered steerer and 12mm thru-axles delivers a light, comfortable and precise-steering front end. Keeps the steering light and agile, while positioning the wheel further in front of the rider for stability and confidence on rougher stuff. Plus it reduces the chance of toe overlap on smaller sizes. Built to accept an internally-routed 27.2 dropper seatpost, which shouldnt really be a surprise on a bike that's this off-road capable. Bolts on when you want fenders, disappears when you don't. Explore further, ride freer. The Cannondale Topstone 1 Gravel Bike is capable and versatile built for chasing horizons, exploring routes less travelled or accelerating your commute.
