Product Description
Get dirty and go. The 2021 Cannondale Topstone NEO SL 2 is a pedal assist all-road bike that will move you over the river, through the woods and to the office on your morning commute.
With a powerful eBikemotion pedal-assist motor and battery, the Cannondale Topstone NEO SL 2 delivers more dirt and much less hurt. As gravel, or all-road, bikes go, you’ll enjoy a long-lasting powertrain that helps you climb mountains for hours and have plenty of juice left in the tank for a great night on the town - or around the campfire.
Built with a lightweight but strong alloy frame with a carbon fiber fork, the Cannondale Topstone NEO SL 2 features a Shimano GRX drivetrain and efficient hydraulic disc brakes to ensure quality stopping power and handling on any road or trail you’ll explore.
The eBikemotion powertrain by Mahle offers a range of almost 50 miles with an optional range-extender battery that can help you push rides from around the mountain to around the range, The Cannondale Topstone NEO SL 2 is an adventure cyclist’s dream rig with extra mounting locations on the top tube to facilitate frame bags to enable epic back-country bike-packing trips off the grid.
Wide tire clearance allows for tires up to 42mm on the 700c rims so you can run chunky gravel and dirt setups or downsize to a more traditional road tire width and enjoy long rides with the bike club.
