CannondaleTopstone 2 Alloy 2x Gravel Bike
The Cannondale Topstone 2 Alloy 2x Gravel Bike is a reliable and fun choice for exploring, offering generous tyre capacity, ample gear mounts, stable yet agile steering, and a lightweight frame with a carbon fork for confident riding over rough terrain.
Built for bikepacking and mixed-surface adventures, it features a SmartForm C2 Alloy frame with clearance for 45 mm tyres and a Topstone Carbon fork with three mount bosses on each leg for added versatility. The Shimano 10-speed GRX RX400 gravel groupset delivers light, accurate shifting, paired with GRX RX400 hydraulic disc brakes for reliable stopping power. A 2x setup provides more gears and improved shifting precision over rolling terrain, while the GXD 1.0 tubeless-ready wheelset with Shimano TC500 hubs and WTB Riddler 700 x 37c tyres enhances grip and control. Designed to accept an internally routed 27.2 mm dropper seatpost for improved handling on descents, it also features a Cannondale 3 6061 Alloy seatpost and flared bar for a sturdy, reliable feel.
