Description
This bike is currently offered with a free set of performance HollowGram G-25, 650bs carbon wheels worth £1500, in addition to the alloy wheels supplied. Take advantage of this fantastic offer and you can have two sets of wheels set up, so you'll be ready to ride, no matter the terrain.
Supplied with 650b alloy wheels as standard and wide 47mm tyres, the Cannondale Topstone Carbon 3 Gravel Bike delivers exceptional traction, comfort and control over a range of terrain. This is a bike made for adventures, be that on poor roads, gravel or even trails, and the carbon frame incorporates rear Kingpin suspension to bring extra compliance without adding the weight of a full shock.
Mounts for gear, bottles and mudguards make the Topstone a highly capable choice when it comes to overnighters and longer tours and the gravel-specific GRX 600 components provide reliable and precise shifting and powerful, all-condition braking. A Cannondale Wheel Sensor allows you to record speed, distance and route and view this and other information, using the free app.
The upgraded HollowGram G-25 wheels will be fitted as standard.
