Lachlan Morton riding a Cannondale Synapse through the Australian bush

Far Meets Fast

Synapse has the comfort and compliance to go far, and the stiffness and aerodynamics to get there faster.

It's the bike Lachlan Morton rode on his record-breaking 30-day lap of Australia – engineered to go long and smooth at a WorldTour-level pace.

Performance, Guaranteed

Cannondale developed Synapse alongside its pro riders, who used, abused and refined it until it met their exacting standards.

Built on decades of experience and backed by Cannondale's lifetime frame warranty, it's ready for whatever you throw at it.

StashPort downtube storage on the Cannondale Synapse Carbon 2

Stash It

An integrated StashPort in the down tube gives secure, hidden storage for a spare tube, tools and snacks.

Your essentials stay out of the way and out of the wind, and your jersey pockets stay free for the long days.

Paved or Unpaved

Generous tyre clearance lets Synapse run wide, supple tyres for extra comfort and grip.

Broken tarmac, rough lanes and the occasional gravel shortcut are all fair game, without giving up the speed of a true road bike.
