Wheel Size
650b
Number of Gears
11 gear(s)
- Refined geometry and dialed endurance fit rider position deliver an experience that's stable, composed and comfortable without losing that spark
- The dual-suspension Topstone's Kingpin rear suspension and Lefty Oliver suspension gravel fork absorb bumps and road vibration for comfort, control and pure gravel performance
- Kingpin gives you up to 30mm of rear suspension (deflection at the seat and rear axle combined) using a thru-axle pivot in the seat to improve comfort, traction and control
- Lefty Oliver suspension fork delivers up 30mm of bump-smoothing travel for comfort, control and an unwaveringly precise ride on both the smooth stuff and the rough stuff
- Gravel-optimized Shimano GRX 600 shifter and GRX 800 Wide rear derailleur deliver smooth and stable 1 x 11-speed shifting across a wide range of gears
- Shimano GRX 400 hydraulic disc brakes provide greater control and stopping power for confident mixed-terrain riding
- 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
- With Proportional Response, the suspension, frame stiffness and ride-feel are custom tuned by size for an ultrasmooth ride and confident traction for every rider
- High-volume 650b x 47mm tires provide excellent off-road traction and run at low pressures for a smooth, comfortable ride even on rougher terrain
- 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
- Carry plenty of gear and water, thanks to a multiposition mount on the down tube, plus mounts on the top tube, on the seat tube and under the down tube
- Fully fender ready, Topstone features a removable fender bridge on the rear stays that's 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
- With DirectLine cable routing, an internal tube guides cables and housing through the frame from entry to exit for headache-free service
- Built to accept an internally routed 27.2mm dropper seatpost (not included)
- An integrated wheel sensor delivers hyperaccurate speed, route and distance info, bike registration, service reminders and more—all through the free Cannondale app
- Pedals not included
- NOTE: Specs and images are subject to change based on component availability
