The Stealth Pocket 300 is designed specifically for the Cervelo P5. The Stealth Pocket 300 is essentially the same as the 200, but it sits lower to maintain an aerodynamic advantage if you run your bars low. The Stealth Pocket 300 screws into two mounts on the top tube of the P5 behind the stem to store your nutrition essentials. The Stealth Pocket even helps to reduce drag around your headset and spacers thanks to its tapered design.
The interior has plenty of room for several bars and gels and is insulated to help prevent your food from melting. For competitive triathletes who seek the solution to storage problems and want every aero edge possible, the Stealth Pocket needs to be on your P5.
