The Topstone Alloy 1 is Cannondale's most powerful gravel bike in the Alloy line, designed for those who want to make no compromises between asphalt, gravel, and dirt paths while riding with serious component quality. The lightweight SmartForm C2 Alloy frame combined with a full carbon fork absorbs vibrations on long gravel sections and keeps the weight low. Shifting is done with the Shimano GRX 820/600 group in 2x12-speed, designed for precise and reliable shifting even under load. Braking is handled by Shimano GRX 600/400 hydraulic disc brakes. The WTB Riddler 700x37c tires on tubeless-ready WTB ST i23 rims are ready to go right away, but offer enough tire clearance for up to 45 mm if you want even more volume. For those looking for a versatile gravel bike with a high-quality shifting group that performs well both on Sunday rides and on multi-day bikepacking tours.
