Description
With something of a do-it-all mentality, the Cannondale Topstone 105 Disc Gravel Bike is ready for intrepid souls to go explore roads less travelled. Alternatively, it's no less capable of hacking through traffic and acting as a durable, robust and reliable commuting bike. Ride to the office during the week and ride to the hills when the weekend rolls around. Kitted out with trusted Shimano 105 components with plenty of gears to tackle long tough climbs and with enough space in the frame for tyres up to 42mm wide, this bike will eat up the gravel miles.
The geometry feels stable and controlled, but with a slight raciness akin to the endurance road bikes in the Cannondale range, so there's a keenness to ride fast when required. And when you need to strap on your bike packing gear there are multiple bottle cage positions plus mounts on the top tube, so that all your kit is always where you need it.
