Specialized Diverge 4 Sport Carbon - 2026Wild gravel, deep exploration, and 200 mile races take capabilities we only dreamed of a few years ago. We invented SWAT storage and pioneered big tires in gravel, so you know we had to take it to the next level. The Diverge 4 Sport Carbon features a FACT 9r carbon frame, Future Shock 3. 1 suspension, SWAT 4. 0 internal storage, 50mm tire clearance, and a Shimano GRX 600 12 speed drivetrain.
