Streamlined integration.

XLAB's Delta Sonic ML System is a single-bottle carrier that mounts directly into seatposts with a 10mm horizontal rear hole. Attached to the Delta Sonic is the three-finger Gorilla cage, clamping down with 7 pounds of grip. This hydration system allows the bottle to sit close to the saddle, hiding in the rider’s draft without adding on drag.

XLAB has found the following bikes to be compatible with the Delta Sonic: Cervelo P5 and 2013 P3, Scott Plasma, Kestrel 4000, Fuji D6 and Norcom, and BH Aero.
