More give, more go. A gravel bike with real suspension, the Cannondale Topstone Carbon Ultegra RX 2 bike is a machine that's equally capable off-road and comfortable on-road.

  • Features

    • Shimano Ultegra RX 2 x 11 mechanical drivetrain uses a clutch design that cuts chain chatter and maintains crisp, accurate shifting over bumpy ground
    • Hydraulic disc brakes offer excellent stopping power on any terrain
    • Lightweight KingPin suspension system lets you ride harder on dirt and more smoothly on pavement, giving you better control, traction and comfort
    • KingPin system provides up to 30mm of travel at the saddle thanks to a thru-axle pivot joining the seatstays and seat tube
    • Flex zones in the chainstays, seat tube and top tube offer compliance at the saddle and added absorption at the rear axle
    • Comes with big 700C x 37mm tires for grip and comfort, but fits up to 700C x 40mm tires thanks to a roomy design with tons of clearance
    • Also fits smaller 650B wheels with up to 48mm wide tires for riders who are looking for maximum flotation
    • Store gear and water with multiposition mounts on the downtube, top tube, seat tube and under the down tube—there are even mounts on the fork
    • Fully fender ready; a removable fender bridge on the rear stays is there when you need it and gone when you don't
    • Speed Release thru axles offer the stiffness and solid feel of a thru axle with the easy use of a quick-release axle; compatible with most thru-axle wheelsets
    • Direct Line internal cable routing guides the cable and housing through the frame using an internal tube from entry to exit for headache-free service
    • Refined geometry and rider position deliver an experience that's stable, composed and comfortable without losing that spark
    • Built to accept an internally-routed 27.2 dropper seatpost
    • Balanced riding position is upright enough for comfort over the long haul and control for technical off-road terrain, yet still low and forward enough for speedy efficiency
    • OutFront steering geometry keeps the steering light and agile, while positioning the wheel farther in front of the rider for stability and confidence on rougher stuff
    • An integrated wheel sensor delivers hyperaccurate speed, route and distance info, bike registration, service reminders and more—all through the free Cannondale app
    • Suspension and overall frame ride-feel is custom-tuned by size using different carbon layup and tube dimensions
    • Pedals not included; specs and images are subject to change
