DB4 is our answer for riders who want to focus on the ride. The low maintenance Mineral Oil system uses all new lever architecture which features easy adjustment access and ergonomic comfort. The right and left specific stealth lever body design brings the hose parallel to the bar, allowing for an organized cockpit that pairs perfectly with mechanical Eagle Transmission. Consistent heavy-duty power is no surprise, as DB4 shares the same proven caliper architecture as DB8
