Named after a favourite gravel road near Cannondale’s main office, the geometry of the Topstone is based closely on the Synapse — its endurance road platform — and is being pitched as “an ideal weekend tourer, an all-weather commuter, or simply a supremely comfortable all-around road bike”.
Officially, the bike has clearances for 700x42mm tyres, but we suspect you’ll be able to fit 45s into the cavernous fork crown and chainstays. There is no word on whether the bike will play nicely with 650b wheels.
As has become Cannondale’s signature, the bike is built around its ‘Out Front’ geometry, which pairs a slacker-than-average head angle (71 degrees in most sizes) with a 55mm offset fork in a bid to improve high-speed handling.
As is becoming increasingly common in the world of gravel bikes, the Topstone includes provisions for fitting a stealth-routed dropper. The top-spec Topstone Apex1 bike comes with a dropper post operated by a lever that attaches to the clamping area of the bars.
Cannondale isn’t the only large OEM to include provisions to run a dropper on a gravel bike. This makes me think that it can only be a matter of time till SRAM or Shimano comes out with an official solution for operating a dropper with drop bars. This is pure speculation, at this stage… but watch this space.
The bike also has mounts for up to three bottles, a top-tube bag, mudguards and racks, making it a very adaptable platform to build upon.

Why is this bike important?
The keenly priced CAADX — a more traditional, cyclocross-focused model — is a hugely important bike for Cannondale, and in the UK at least, is supposedly its best-selling bike.
I suspect the Topstone, with its more all-round geometry, improved clearances and increased versatility could dethrone the CAADX as number one, so this is one we’ll be watching very, very closely.
