Cannondale Synapse LAB71 Smart Sense Bike Road reimagined. Ride redefined. The Synapse LAB71 Smart Sense sits at the top of Cannondale's endurance road lineup - a bike that earns its place through genuine performance without compromise.

SRAM RED XPLR AXS 1x13 wireless shifting, an integrated power meter, Reserve 42|49 Turbulent Aero carbon wheels with DT Swiss 180 hubs, and the System Bar R-One carbon cockpit make this the rare endurance bike that's as capable and fast as it is comfortable.
