Standard frame-mounted bottles have high aerodynamic drag, so place your bottle at the rear instead. The Delta 300 mounts to 2-hole Cervelo seat posts and the new Quintana Roo PR6. The system includes a Gorilla XT carbon cage which provides a tight 14-pound grip on your bottle. For a complete system, purchase the optional X-Strike Inflation Kit and store up to 4 CO2 cartridges.
