The DELTA SONIC XL allows for a rear seat position and is 0.8" longer than the standard DELTA SONIC
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.
Aerodynamic Design
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.

Instructions
Replaces frame bottle
Standard frame-mounted bottles have high aerodynamic drag, so place your bottle at the rear instead. The DELTAs are mounted on the saddle rails for no measurable drag.
Refills front drink system
Use the DELTAs to refill a front drink system. Just bring the spare bottle forward from the DELTA and refill. If you have the popular XLAB TORPEDO aerobar mounted system then simply replace the empty front bottle with the spare bottle from the DELTA.
Adds an extra bottle
These systems are also ideal for longer training rides or Century rides, where an extra bottle is necessary so you can have your favorite mix with you at all times.
