Made specifically for Ritchey clamp seat posts found on the Cervelo P5, Scott Plasma, and Kestrel triathlon bikes, the XLAB Delta Sonic XL Rear hydration system has a .8" longer Delta Sonic carrier rod, so it'll work behind almost all types of saddles and saddles that are situated farther back. The simple stainless steel construction is quick and easy to attach. The Delta Sonic XL features a XLAB Gorilla XT cage, which will put your bottles in a choke hold so they can't go jumping out and bouncing down the road behind you. If you're looking for a rear hydration system that is simple and secure, the Delta Sonic XL is the answer.
