Cannondale Topstone Carbon 5 Bike

Features

• Shimano GRX 800/600 2 x 11-speed drivetrain uses an adjustable chain stabilizer to cut chain chatter and maintain crisp, accurate shifting over bumpy ground
• Lightweight KingPin rear 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 30 mm of travel at the saddle thanks to a thru-axle pivot joining the seatstays and seat tube
• Thru-axle pivot locks the left and right seatstays together, preventing independent rotation for a solid feel and an instantaneous response
• Comes with big 700c x 37 mm tires for grip and comfort, but fits up to 700c x 40 mm tires (not included) thanks to a roomy design with tons of clearance
• Also fits smaller 650b wheels with up to 48 mm wide tires for riders seeking maximum flotation
• Fully fender ready: A removable fender bridge on the rear stays is there when you need it and gone when you don’t
• Store gear and water with multiposition mounts on the top tube, seat tube and under the down tube—there are even mounts on the fork
• 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 cables 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 mm dropper seatpost (not included)
• Balanced riding position is upright enough for comfort over the long haul and control over 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 are custom-tuned by size using different carbon layup and tube dimensions
• Pedals not included
• Specs and images are subject to change
