So Smooth
With Synapse, comfort is built in. Discreet flex zones in the rear triangle, seat tube and seatpost absorb road chatter and bumps without adding weight or isolating you from the ride experience.

So Fast
Lightweight carbon construction. Subtle aerodynamic shaping of the frame and fork. Size-specific design for perfectly tuned stiffness. It all adds up to a machine that loves to fly.

So Capable
With a comfortably balanced riding position, confidence-inspiring handling, room for 35mm wide tires for cushion and grip, and plenty of gear/bottle mounts, Synapse is ready to rock on any road, anywhere.

So Brilliant
Ride assured, with increased visibility and enhance awareness out on the road. Our SmartSense system of intelligent lights (and optional rear-facing radar) makes it easy to ride smart.
