Cannondale Topstone 4 Gravel Bike 2021
ALL NEW TOPSTONE - BORN TO ROLL AND ROAM
Named after a favorite dirt road loop near our headquarters in Connecticut, Topstone is pure gravel goodness.
With its high-volume tires, confident rider position and sporty handling, it is ready to smash out big miles
on the backroads, explore routes less travelled, or smooth out the chop on your morning commute.
- Big tire clearance: Built with plenty of room for tires up to 42mm wide, for comfort, grip and adventurous capability.
- Outfront steering geometry: A slack head angle paired with a long 55mm fork rake delivers great stability at speed and great agility where needed. Just what you need for mixed-surface confidence or multi-day adventures.
- Confident rider position: Topstone shares similar stack and reach measurements with our synapse Endurance bikes, for a confident and sporty riding position.
- Full carbon fork: Full carbon forks on all models, with tapered steerers and 12mm thruaxles, for a light, comfortable and precise-steering front end.
