Rider on a Cannondale Topstone Carbon on a rough gravel track

Smoother Ride, Swifter Pace

KingPin rear suspension brings rough-stuff-smoothing comfort to gravel like nothing else, taking the sting out of ruts, roots and rocks.

More confidence and more control mean getting somewhere new a whole lot quicker. If you thought suspension was just for mountain bikes, think again.

Rider on a Cannondale Topstone Carbon on a cypress-lined gravel road

Easy to Live With

Everything on Topstone Carbon is there for simplicity and compatibility: a threaded bottom bracket, a standard external seat binder and low-maintenance suspension.

Less time in the workshop, more time riding.
