Cannondale Topstone 3 2025 Gravel Bike

The Cannondale Topstone 3 is a versatile gravel bike built for riders who want confident performance across mixed terrain without stepping into premium price territory. Its lightweight SmartForm C2 aluminium frame delivers stable, predictable handling on everything from smooth tarmac to rough back roads, while the tapered head tube and internal cable routing add strength and long-term durability. A full carbon Topstone fork helps smooth out vibrations and improves front-end precision, making longer rides more comfortable and controlled.

Shimano’s Sora 9-speed drivetrain provides reliable, straightforward shifting across a wide gear range suited to climbing, cruising and everything in between. Mechanical disc brakes offer dependable stopping power in wet or dry conditions, while the sturdy GXD wheelset paired with Victoria Terreno tyres balances rolling efficiency with confident grip on loose surfaces. With rack and mudguard compatibility built in, the Topstone 3 is equally at home commuting, exploring country lanes or heading off on multi-day gravel adventures.
