Working closely with Cervélo™ 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.
The DELTA SONIC XL allows for a rear seat position and is 0.8" longer than the standard DELTA SONIC
The DELTA SONIC XL allows the bottle to be close to the saddle, hiding in the rider’s draft and provides clean air flow.
Reliable & Customizable
The DELTA SONIC XL fits snug into the seat post providing a sturdy non-sway bottle mount, for fast and safe access to your bottle. The DELTA SONIC XL rod can slide along the seat post for the best customized fit for you. XLAB™ recommends a 1" insertion minimum into the seatpost.
XLAB™ has found these bikes to be compatible with the DELTA SONIC XL.
