Kingpin Suspension
Delivering a smooth ride without the added weight and complexity of a shock and links, Kingpin is our answer for the most demanding gravel riders. Whether you need more comfort to go long, more traction to push beyond or more give to take on the tech - Kingpin is the maintenance-free, lightweight answer to your prayers.
Engineered Simplicity
Low-friction bushings on the Kingpin thru-axle offer smooth action, maintenance-free reliability and over 100 grams of weight savings vs conventional cartridge bearings.
Clearance & Compatibiity
The new dropped chainstay design lets you run big volume tires (up to 700x45mm or 27.5x2.1", with 6mm of mud-shedding clearance on each side), all with a standard dish rear wheel for easy interchangeability.
Tuned for the rider
Our Proportional Response size-specific construction creates optimal frame stiffness and compliance for each frame size, so that every rider has the ideal ride feel and comfort of Kingpin.
SmartSense Ready
Make every ride better with enhanced visibility and awareness. The SmartSense-ready frame means it's easy to upgrade to our system of intelligent running lights and rear-facing radar.
OutFront Steering Geometry
Confident stability meets nimble agility. An extra long fork offset paired with a slack head angle keeps the steering light and lively, yet delivers unreal confidence at speed and in the rough stuff.
Connected
An integrated wheel sensor delivers hyper-accurate speed, route and distance info while you ride, registers your bike, reminds you of needed service and more, all through the free Cannondale App.
Dropper Ready
Built to accept an internally-routed 27.2mm dropper seatpost, which shouldn't really be a surprise on a bike this off-road capable.
