Key Features of the Cannondale Topstone Carbon 3
The Topstone Carbon 3 shines thanks to its smart engineering and rider-focused design. Here’s what sets this gravel bike with rear suspension apart:
Lightweight Carbon Frame with KingPin Suspension
Built from high-quality Topstone Carbon with Proportional Response construction, the frame includes the unique KingPin rear suspension system. This provides approximately 30mm of rear travel for better grip and comfort on rough terrain—without pivots, linkages, or maintenance-heavy parts. The design keeps the bike lightweight (around 10-10.3 kg depending on size and build) while enhancing control and reducing fatigue on long rides.
Additional highlights include downtube StashPort internal storage (on select variants), dropper post compatibility, multiple bottle/gear mounts, removable fender bridge, and UDH rear derailleur hanger for durability.
Responsive Geometry and Huge Tire Clearance
Modern gravel geometry offers a balanced, confident ride with a slack head angle for stability and short chainstays for nimble handling. Tire clearance reaches up to 45-50mm (often with 700c x 45c WTB Riddler or similar), allowing riders to swap between fast-rolling slicks and aggressive knobbies for mixed surfaces.
Reliable Shimano GRX Drivetrain
Equipped with a Shimano GRX gravel-specific groupset (typically GRX 820/610 or blended 800/600 in 2x or 1x configurations), it delivers precise shifting and wide gearing for steep climbs or high-speed flats. Hydraulic disc brakes provide powerful, modulated stopping in all conditions.
Wheels, Tires, and Finishing Kit
Rolling on WTB ST i25 TCS tubeless-ready rims with Shimano hubs, paired with high-grip WTB Riddler or similar tires (45c x 700). The cockpit features a comfortable Cannondale alloy bar, stem, and saddle setup optimized for long-distance comfort.
