Cannondale Topstone Carbon Ultegra Disc RX2 Gravel Road Bike 2020
With the Topstone Carbon Ultegra Disc RX2 Gravel Road Bike Cannondale have pushed the boundaries of comfort, compliance and handling to deliver a ride that will help you ride further on roads that would otherwise not have been possible on a fast drop bar setup. The Ultegra groupset features the RX rear derailleur that keeps the drivetrain tighter, reducing chain slap, and that in turn helps to reduce noise and improve performance over tough surfaces.
Innovative KingPin engineering in the frame delivers up to 30mm of suspension that smooths out the road, for a silky ride feel that helps you stay stronger for longer. Add to this the LockR Pivot that secures the seatstays and the bike is responsive, predictable and stable. Thanks to Endurance Fit geometry you are placed into a position that feels planted and secure, inspiring confidence when the terrain becomes technical, yet there's also a feeling of speed that still lets you get low and fast if needed.
When it comes to hills the 11-34t cassette and 46/30T chainset will have plenty of gears for easy climbing, even when you've made full use of the ample mounting points for water bottles, bags and accessories, and the bike is fully laden for a big adventure.
