XLAB Delta Sonic XL Bottle Mount
The DELTA SONIC XL allows for a rear seat position and is 0.8" longer than the standard DELTA SONIC
Fits seat posts with 10 mm horizontal hole
The DELTA SONIC XL allows the bottle to be close to the saddle, hiding in the rider's draft and provides clean air flow
Working closely with Cervelo and their wind tunnel testing results, XLAB developed an aerodynamic single rear system specific to Ritchey clamp seat posts with a 10 mm horizontal rear hole.
