Cannondale Topstine Carbon 2 Left Gravel Bike
Discover the ultimate dual-suspension gravel bike engineered for conquering rugged dirt roads and singletrack trails effortlessly. Equipped with the innovative Kingpin system and Lefty fork, this bike breaks boundaries, making no terrain impassable. Designed to thrive on gravel and dirt roads, rough pavement, and trails, it's built for gravel riding, back road exploration, bike packing, and off-road adventures. Featuring a lightweight Topstone Carbon frame with Kingpin suspension and Lefty Oliver gravel suspension fork offering 30mm travel, this bike ensures a smooth, agile ride. With WTB KOM Light rims, it combines durability with performance. Kingpin Suspension delivers unparalleled comfort, traction, and agility without the added weight and complexity of traditional shocks, making it ideal for demanding gravel riders. Meanwhile, Lefty Oliver provides the smoothest, most precise handling with 30mm of bob-free travel and ample tire room. Loaded with gear and waterbottle mounts on the frame and fork, the Topstone Carbon is ready for extended adventures. Its OutFront steering geometry ensures stability through rough terrain while maintaining lightness and agility elsewhere, allowing you to corner like a boss and emerge with a smile. Don't just ride, conquer every path with confidence and ease.
