Standard frame-mounted bottles have high aerodynamic drag, so place your bottle at the rear instead. The Delta Sonic is mounted behind the saddle for no measurable drag. The mounting rod fits snugly into the Cervélo seat post providing a sturdy non-sway bottle mount, for fast and safe access to your bottle. With years of Aerospace engineering experience, XLab products are designed to be extremely aerodynamic, wind tunnel tested, light and dependably durable. When you get an XLab you know you’re buying quality.
