Working closely with Cervélo™ and their wind tunnel testing results, XLAB developed an aerodynamic single rear system specific to Ritchey clamp seat posts found on the Cervélo™ P5, Scott Plasma™ and Kestrel™ triathlon bikes

The DELTA SONIC allows the bottle to be close to the saddle, hiding in the rider’s draft and provides clean air flow

The DELTA SONIC fits snugly into the seat post providing a sturdy non-sway bottle mount, for fast and safe access to your bottle. The DELTA SONIC rod can slide along the seat post for the best customized fit for you.

Pair the DELTA SONIC with the aerodynamic STEALTH POCKET 200. This bag mounts to the top tube on the 2 bosses. Capacity of 20.4 cu.in, this bag can hold the longest energy bars plus some gels and salt tablets.
