Race-tuned. Adventure-approved. The Diverge 4 gravel bike is built for full-gas race days and off-grid epics. With Future Shock 3.0, our most responsive frame ever, massive tire clearance, and the biggest internal storage in gravel, the best gravel bike in the world just got better. Chase the horizon—or your rivals—it’s built for both.
The Diverge 4 Expert pairs a FACT 9r carbon frame and Future Shock 3.2 front suspension with Shimano’s new GRX Di2 1x12-speed electronic groupset, Roval Terra C carbon wheels, and SWAT 4.0 internal downtube storage.
