The Cannondale Topstone CAAD Lefty is the most aggressive version of the Topstone CAAD family: an aluminium gravel bike with a 40 mm Lefty Oliver suspension fork, made for riders seeking challenging dirt roads, fast descents and long off-road adventures. The Shimano GRX 1x12 groupset with a 10-51 cassette and 45 mm WTB Vulpine tires complete a package ready to go further. Model year 2027.
The Topstone CAAD frame in SmartForm C1 aluminium is designed from the outset with suspension-ready geometry: the Lefty Oliver integrates naturally, soaks up bumps and keeps the front wheel planted, for more control, more traction and less fatigue on long rides.
