A New Take on the Road Bike Smoother Than Ever The Synapse is incredibly comfortable thanks to the integrated flex zones in the rear triangle, seat tube, and seat post. These zones absorb vibrations and bumps without negatively impacting the frame's weight or riding characteristics. Super Fast The sleek, aerodynamically optimized shapes of the frame and fork make the Synapse even faster than its predecessors. Additionally, your proportions are perfectly accounted for with Proportional Response, ensuring you sit perfectly on the bike and can really put the pedal to the metal.
