Model Description
Smooth. Precise. And built to stay that way. Synapse Carbon 2 Di2 pairs an endurance-optimised carbon frame with Shimano’s peerless Ultegra Di2 shifting and the race-bred DT Swiss ERC 45 wheelset. Designed for the rider who appreciates the feel of a fast bike built to go the distance—and the silence of a drivetrain that’s always in the right gear. Add in massive tire clearance and sleek integration, and it’s clear: this thing’s more than ready.
