The speed and handling of our award-winning Synapse road bike, with the comfort and control of a more upright riding position, makes Synapse Flat Bar the ultimate high-performance fitness machine. Proportional Response Design of this carbon frame ensures that every rider, regardless of size, enjoys the same ride-feel and handling. Each size gets its own custom carbon layup, tube dimensions, and geometry. Cannondale even uses two different steerer diameters and fork rakes through the size run for a truly tailored feel. Micro-Suspension in the frame, fork, and seatpost keeps you protected from shocks and vibration yet connected to the feel of the ride. Hydraulic disc brakes offer better modulation and better power for complete braking control in all conditions.
