XLab Delta Sonic Rear Mount System

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. Strong and sturdy mount eliminates rear carrier sway and the Gorilla XT Cage has a tight 14lb grip on bottles eliminating unexpected launches. Very adjustable with up to 1.25" of adjustment to ensure carrier sits close to the saddle.  If the saddle is in the rearward position, you may want to look at the Delta Sonic XL. 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 rod can slide along the seat post for the best customized fit for you. XLAB recommends a 1" insertion minimum into the seatpost.

Quality well made product, does exactly what it says on the tin, I have had bottles 'eject 'in the past. After a few rides can`t see that happening with the XLAB.
Awesome bottle mount. They're not kidding when they say its a Gorilla's grip! No bottle launches coming from this dog. Easy installation - highly recommended.
