XLAB Delta 200

The Xlab Delta 200 is a rail-mounted hydration system that stores your spare bottle the aero way: tucked behind you. Frame-mounted bottles have high aerodynamic drag, which adds up when you're on the course for a tri or time trial. The Delta system mounts securely to the saddle rails using vibration-resistant hardware. Included is XLAB's Gorilla Cage, a lightweight carbon fiber bottle cage that grips your bottle with 7 pounds of grip.
