Specialized has released the Diverge Pro 4, a human-powered gravel bike priced at $8,249, positioned as a single machine capable of handling racing, adventure riding and long-distance touring. Reviewed on rough Colorado trails, the bike is built to excel on technical, rutted terrain while remaining competent on smoother roads, distinguishing it from the brand's electric Turbo Creo 2 model reviewed previously.

The standout feature is Future Shock 3.3, an updated suspension system housed between the head tube and stem that allows the handlebars to move vertically while the fork and front wheel stay rigid, using hydraulic damping to absorb high-frequency impacts without altering steering geometry. Specialized claims laboratory tests showed up to a 53 percent reduction in peak impact at the handlebars compared with rival setups, and the reviewer reported noticeably less arm and upper-body fatigue on long rides. The system's 20mm of travel can be adjusted on the fly via a stem-mounted dial, and the bike also gains a reworked FACT 9r carbon frame with longer reach for improved weight distribution compared with the previous Diverge Pro 3.
